Spatiotemporal expression of alternatively spliced IGF-I mRNA in the rat costochondral growth plate. (1/822)

IGF-I acts as a local proliferation and maturation factor for chondrocytes in the growth plate. However, the expression of different alternative IGF-I mRNA classes in the growth plate has not been characterized. Using quantitative reverse transcription PCR, the abundance of each alternative IGF-I mRNA class in resting, proliferative and hypertrophic chondrocytes was measured in rat costochondral growth plates. Class 1Ea mRNA was the most abundant IGF-I transcript overall and was highly expressed in proliferative chondrocytes at 2 and 4 weeks of age; by 6 weeks, the majority of 1Ea mRNA expression had shifted to hypertrophic chondrocytes. Class 1Eb mRNA was the second most abundant transcript and its distribution was uniform across all the cell types at 2 weeks of age. The expression pattern changed with increasing age such that at 6 weeks a gradient existed with hypertrophic chondrocytes expressing higher levels of 1Eb than resting chondrocytes. Class 2Ea mRNA was constitutively expressed at low levels across the growth plate at all ages, while class 2Eb mRNA expression was negligible. The distribution of total IGF-I mRNA also shifted across growth plate cell types as the animals aged from 2 to 6 weeks. These findings suggest that IGF-I class 1 mRNA plays the predominant role in the maturation of the growth plate.  (+info)

The bcl-2 knockout mouse exhibits marked changes in osteoblast phenotype and collagen deposition in bone as well as a mild growth plate phenotype. (2/822)

Histological examination of long bones from 1-day-old bcl-2 knockout and age-matched control mice revealed no obvious differences in length of bone, growth plate architecture or stage of endochondral ossification. In 35-day-old bcl-2 knockout mice that are growth retarded or 'dwarfed'. the proliferative zone of the growth plate appeared slightly thinner and the secondary centres of ossification less well developed than their age-matched wild-type controls. The most marked histological effects of bcl-2 ablation were on osteoblasts and bone. 35-day-old knockout mouse bones exhibited far greater numbers of osteoblasts than controls and the osteoblasts had a cuboidal phenotype in comparison with the normal flattened cell appearance. In addition, the collagen deposited by the osteoblasts in the bcl-2 knockout mouse bone was disorganized in comparison with control tissue and had a pseudo-woven appearance. The results suggest an important role for Bcl-2 in controlling osteoblast phenotype and bone deposition in vivo.  (+info)

A mouse model for achondroplasia produced by targeting fibroblast growth factor receptor 3. (3/822)

Achondroplasia, the most common form of dwarfism in man, is a dominant genetic disorder caused by a point mutation (G380R) in the transmembrane region of fibroblast growth factor receptor 3 (FGFR3). We used gene targeting to introduce the human achondroplasia mutation into the murine FGFR3 gene. Heterozygotes for this point mutation that carried the neo cassette were normal whereas neo+ homozygotes had a phenotype similar to FGFR3-deficient mice, exhibiting bone overgrowth. This was because of interference with mRNA processing in the presence of the neo cassette. Removal of the neo selection marker by Cre/loxP recombination yielded a dominant dwarf phenotype. These mice are distinguished by their small size, shortened craniofacial area, hypoplasia of the midface with protruding incisors, distorted brain case with anteriorly shifted foramen magnum, kyphosis, and narrowed and distorted growth plates in the long bones, vertebrae, and ribs. These experiments demonstrate that achondroplasia results from a gain-of-FGFR3-function leading to inhibition of chondrocyte proliferation. These achondroplastic dwarf mice represent a reliable and useful model for developing drugs for potential treatment of the human disease.  (+info)

Aberrant death in dark chondrocytes of the avian growth plate. (4/822)

Growth plate chondrocytes of embryonic chick femurs were examined by electron microscopy, cytophotometry and autoradiography. Apart from the well-described 'light' chondrocyte, a different 'dark' type of chondrocyte was present, comprising 10 - 35% of the cell population. They were found at all stages of chondrocyte differentiation and in all ages of the femurs studied. Well developed rough endoplasmatic reticulum and Golgi complex, many secretory vesicles, energetically active mitochondria and a lot of glycogen, indicating high activity of the cytoplasm, were combined with low RNA synthesis, gentle margination and scattered compaction of the chromatin. DNA cytometry revealed that most of dark cells were diploid, but 15 - 30% were tetraploid, with the absence of an S-phase. Substantial loss of DNA was found in about 10% of dark chondrocytes. The TUNEL reaction demonstrated a limited number of DNA strand breaks. Advanced dark cells possessed the nuclear features of both apoptosis and necrosis. Besides chromomeric-chromonemic compaction, a chromatin arrangement similar to that of prometaphase and metaphase, as well as amitotic nuclear segregation, all of them degenerative, were found. Our interpretation is that the dark chondrocytes undergo an aberrant type of cell death which may be combined with aberrant cell cycle. Cell death of dark chondrocytes is preceded by a pre-mortal burst of secretion.  (+info)

Growth plate cartilage formation and resorption are differentially depressed in growth retarded uremic rats. (5/822)

To characterize the modifications of growth plate in individuals with growth impairment secondary to chronic renal failure, young rats were made uremic by subtotal nephrectomy (NX) and, after 14 d, their tibial growth plates were studied and compared with those of sham-operated rats fed ad libitum (SAL) or pair-fed with NX (SPF). NX rats were growth retarded and severely uremic. Growth plate height (mean +/- SD) was much greater (P<0.05) in NX (868.4+/-85.4 microm) than SAL (570.1+/-93.5 microm) and SPF (551.9+/-99.7 microm) rats as a result of a higher (P<0.05) hypertrophic zone (661.0+/-89.7 versus 362.8+/-71.6 and 353.0+/-93.9 microm, respectively). The increased size of the growth plate was associated with a greater number of chondrocytes and modifications in their structure, particularly in the hypertrophic zone adjacent to bone. In this zone, chondrocytes of NX animals were significantly (P<0.05) smaller (12080.4+/-1158.3 microm3) and shorter (34.1+/-2.5 microm) than those of SAL (16302.8+/-1483.4 microm3 and 37.8+/-2.0 microm) and SPF (14465.8+/-1521.0 microm3 and 36.3+/-1.8 microm). The interface between the growth plate cartilage and the metaphyseal bone appeared markedly irregular in NX rats. Kinetics of chondrocytes was also modified (P<0.05) in the NX rats, which had lower cell turnover per column per day (5.4+/-0.9), longer duration of hypertrophic phase (89.0+/-15.2 h), and reduced cellular advance velocity (7.4+/-2.2 microm/h) compared with SAL (8.0+/-1.6, 32.1+/-6.7 h, and 11.3+/-2.7 microm/h) and SPF (7.2+/-1.1, 34.8+/-5.1 h, and 10.1+/-2.5 microm/h). Cell proliferation was no different among the three groups. Because the growth plates of SPF and SAL rats were substantially not different, modifications observed in the NX rats cannot be attributed to the nutritional deficit associated with renal failure. These findings indicate that chronic renal failure depresses both the activity of the growth plate cartilage by altering chondrocyte hypertrophy and the replacement of cartilage by bone at the metaphyseal end. The two processes are differentially depressed since cartilage resorption is more severely lowered than cartilage enlargement and this leads to an accumulation of cartilage at the hypertrophic zone.  (+info)

Measurement of biological activity of somatotropin in hypophysectomized rats. (6/822)

AIM: To develop a method for measurement of biological activity of recombinant DNA-derived somatotropin (rhGH). METHODS: The effects of varying the route, frequency and period of administration of GH, the sex of test animals on the biological responses, body weight gain (BWG), and tibial epiphyseal width (TEW), of hypophysectomized (Hypox) rats were compared, respectively. 4-d BWG, 6-d BWG, and 6-d TEW tests were carried out simultaneously in the same group of Hypox rats to determine the biopotency of GH preparations according to a parallel line bioassay (6-point assay). The final result was chosen from the test which had smaller values for the index of precision (lambda) and the average rate of fiducial limits (ARFL) than other tests. RESULTS: No significant differences in the responses between male and female rats, between sc and im, once daily and twice daily injections of bGH were found. But the BWG and TEW of Hypox rats injected with 0.045 and 0.135 IU.d-1 of bGH for 6 d were significantly greater than that for 4 d. Both 4-d BWG test and 6-d BWG test in the range from 0.020 to 0.500 IU.d-1 had values for lambda = 0.0660 and 0.1747, and for r = 0.9000 and 0.9237, respectively. Three estimates of rhGH preparation compared with the International Standard for somatotropin (IShGH), 4.6132, 3.9829, and 4.8023 IU/ampoule, were obtained separately from 4-d BWG test, 6-d BWG test and 6-d TEW test. And the result from 6-d BWG test was reported finally because it had smaller values for lambda and ARFL (0.0608 and 37.907%) than other two tests. CONCLUSION: Both BWG test and TEW test can be carried out simultaneously in the same group of Hypox rats. 6-d BWG test seemed to be more suitable for potency determination of GH preparations than 4-d BWG test and 6-d TEW test.  (+info)

Immunohistochemical observations on the initial disorders of the epiphyseal growth plate in rats induced by high dose of vitamin A. (7/822)

The initial disorders of the epiphyseal growth plate cartilage were immunohistochemically examined in the proximal tibia of rats administered a high dose of vitamin A. Male Wistar rats were given 100,000 IU/100 g body weight/day of vitamin A for administration periods of 1 to 5 days (Day 1 to 5) from 4 weeks after birth or were given deionized water and used as control. They were sacrificed after 5-bromo-2'-deoxyuridine (BrdU) injection on Day 1 to Day 5 to remove the tibiae. The tibiae were processed for immunohistochemical examinations using antibodies against type I, II, X collagens and BrdU. BrdU-incorporated chondrocytes and type X collagen-negative area were reduced since Day 2 and type X collagen-positive area was reduced since Day 4. The cartilage matrix partially lost type II collagen and deposited type I collagen in the epiphyseal growth plate near the periosteum on Day 5. These findings suggest that a high dose of vitamin A initially disturbed the differentiation from resting to proliferating chondrocytes, subsequently inhibited the differentiation from proliferating to hypertrophic chondrocytes, caused the chondrocytes to deviate from the process of normal differentiation, and finally resulted in the deformation of the epiphyseal growth plate.  (+info)

Cathepsin expression during skeletal development. (8/822)

Cysteine proteinases, cathepsins B, H, K, L and S, have been implicated in several proteolytic processes during development, growth, remodeling and aging, as well as in a variety of pathological processes. For systematic analysis of cathepsin gene expression we have produced cDNA clones for mouse and human cysteine cathepsins. Northern analysis of a panel of total RNAs isolated from 16-19 different human and mouse tissues revealed the presence of mRNAs for cathepsin B, H, K, L and S in most tissues, but each with a distinct profile. Of the different cathepsin mRNAs, those for cathepsin K were clearly the highest in bone and cartilage. However, relatively high mRNA levels for the other cathepsins were also present in these tissues. To better understand the roles of different cathepsins during endochondral ossification in mouse long bones, cathepsin mRNAs were localized by in situ hybridization. Cathepsin K mRNAs were predominantly seen in multinucleated chondroclastic and osteoclastic cells at the osteochondral junction and on the surface of bone spicules. The other cathepsin mRNAs were also seen in osteoclasts, and in hypertrophic and proliferating chondrocytes. These observations were confirmed by immunohistochemistry and suggest that all cysteine cathepsins are involved in matrix degradation during endochondral ossification.  (+info)

7.1. Insulin-like growth factors (IGF-I & IGF-II). Of the growth factors, those with the most potent effects on growing skeletal tissue are the IGFs, previously known as somatomedins. IGFs are synthesised in the liver and circulate bound to carrier proteins (Froesch et al., 1985). The major factors regulating IGF concentrations in serum are growth hormone, nutritional intake and thyroid hormones, the latter being necessary for growth hormone secretion. The traditional view was that growth hormone acted indirectly on the growth plate via IGF-I, a potent mitogen for growth plate chondrocytes. However, there is increasing evidence that growth hormone has direct effects on the growth plate (Tripper et al., 1989). (This close relationship between circulating IGFs and growth hormone will be discussed in more detail in the chapter covering the hormonal regulation of growth.). In addition to having effects on the growth plate chondrocytes, locally synthesised and circulating IGFs retained in bone matrix ...
Every one of the long skeletal bones in the body has a growth plate that governs its rate of the bone growth and development. This growth plate, or physis, is located near the end of each long bone, adjoining the head of the bone, called the epiphysis. The release of growth hormone, somatotropin, interacts with the cells of the growth plate during periods of cellular creation. As a child grows, the growth plates harden by a process known as ossification of the bone cells, eventually disappearing when the body reaches maturity. Thus, growth plate injuries are, by definition, damage sustained by a child or an adolescent.. Bones such as the tibia and fibula (lower leg), the radius (forearm), and the femur (thigh) are structures that commonly sustain growth plate damage. The growth plate in a child or adolescent is often softer than the supporting ligaments and connective tissues, because bones form more slowly, rendering the growth plate more vulnerable to fracture.. The period in physical ...

T1 - 24R,25-Dihydroxyvitamin D3 [24R,25(OH)2D3] controls growth plate development by inhibiting apoptosis in the reserve zone and stimulating response to 1α,25(OH)2D3 in hypertrophic cells. AU - Boyan, B. D.. AU - Hurst-Kennedy, J.. AU - Denison, T. A.. AU - Schwartz, Z.. PY - 2010/7/1. Y1 - 2010/7/1. N2 - Previously we showed that costochondral growth plate resting zone (RC) chondrocytes response primarily to 24R,25(OH)2D3 whereas prehypertrophic and hypertrophic (GC) cells respond to 1α,25(OH)2D3. 24R,25(OH)2D3 increases RC cell proliferation and inhibits activity of matrix processing enzymes, suggesting it stabilizes cells in the reserve zone, possibly by inhibiting the matrix degradation characteristic of apoptotic hypertrophic GC cells. To test this, apoptosis was induced in rat RC cells by treatment with exogenous inorganic phosphate (Pi). 24R,25(OH)2D3 blocked apoptotic effects in a dose-dependent manner. Similarly, apoptosis was induced in ATDC5 cell cultures and ...

When grown separately in monolayer culture, they continue to express their zone-specific phenotype, providing a model for assessing cell-maturation-dependent expression of molecules associated with differentiation.

The von Hippel Lindau tumor suppressor protein (pVHL) is a component of a ubiquitin ligase that promotes proteolysis of the transcription factor hypoxia-inducible-factor 1alpha (HIF1alpha), the key molecule in the hypoxic response. We have used conditional inactivation of murine VHL (Vhlh) in all cartilaginous elements to investigate its role in endochondral bone development. Mice lacking Vhlh in cartilage are viable, but grow slower than control littermates and develop a severe dwarfism. Morphologically, Vhlh null growth plates display a significantly reduced chondrocyte proliferation rate, increased extracellular matrix, and presence of atypical large cells within the resting zone. Furthermore, stabilization of the transcription factor HIF1alpha leads to increased expression levels of HIF1alpha target genes in Vhlh null growth plates. Lastly, newborns lacking both Vhlh and Hif1a genes in growth plate chondrocytes display essentially the same phenotype as Hif1a null single mutant mice suggesting that

The growth plate, which is also known by the name of epiphyseal plate, is an area of growing tissues along the end of the long bones in a child. The growth plate determines how the length and shape of the bone will be once the child attains puberty. Normally, the growth plate closes once the child has attained puberty. Thus for females, the normal age at which time the growth plate should close is between 12-14 years and for males it is between 14-16 years.

Herein, we review the regulation of differentiation of the growth plate chondrocytes by G-proteins. In connection with this, we summarize the current knowledge regarding each family of G-protein α subunit, specifically, Gα(s), Gα(q/11), Gα(12/13), and Gα(i/o). We discuss different mechanisms involved in chondrocyte differentiation downstream of G-proteins and different G-protein-coupled receptors (GPCRs) activating G-proteins in the epiphyseal chondrocytes. We conclude that among all G-proteins and GPCRs expressed by chondrocytes, Gα(s) has the most important role and prevents premature chondrocyte differentiation. Receptor for parathyroid hormone (PTHR1) appears to be the major activator of Gα(s) in chondrocytes and ablation of either one leads to accelerated chondrocyte differentiation, premature fusion of the postnatal growth plate, and ultimately short stature.

The growth plates are much softer than other regions of the bones, therefore are more prone to injury. Since most of the longitudinal growth of bones occurs up to eight months of age, growth plate injuries that occur after this point are not as devastating. A portion of the damaged growth plate may remain functional (open) and thus the bone and limb becomes twisted. Surgery is generally done as soon as possible after this type of injury occurs. Anatomy. ...
Growth plates are areas of cartilage at the ends of the bodys long bones. Because the growth plates are the last portion of a childs bones to harden (ossify), they are particularly vulnerable to fracture.

The goal of our investigation was to explore the mechanism by which hypoxia regulates growth plate chondrocyte survival. At low O2 tension, chondrocytes were refractory to a staurosporine (i.e., apoptosis-inducing) challenge. To determine whether hypoxic survival was due to the expression of HIF-1, we evaluated the response of HIF silenced cells to staurosporine. Both, silenced cells and control chondrocytes were equally sensitive to the apoptogen challenge. To learn if resistance was mediated by the proteins of the autophagic pathway, we examined the expression of Beclin 1 and LC3. Both proteins were present in the growth plate as well as in N1511 chondrocytes. Moreover, silencing of Beclin 1 resulted in enhanced chondrocyte death. Thus, this gene served to maintain chondrocyte survival activity. Besides serving a cytoprotective role, it is known that autophagy can function in cell death. Accordingly, to ascertain if autophagy might also sensitize cells to apoptosis, we activated autophagy and examined
GH has physiological functions in many tissues, but the cellular targets for direct effects of GH remain ill defined in complex tissues such as the growth plate in which the contribution of direct vs. indirect actions of GH remains controversial. The Janus kinase (Jak)-signal transducer and activator of transcription (STAT)-5 pathway is activated by GH, so we developed a method to visualize nuclear Stat5b and phosphorylated Stat5 in single cells in response to a pulse of GH. Hep2 cells did not show a Stat5 phosphorylation (pY-Stat5) response to GH except in cells transfected to express GH receptors. ATDC5 cells express GH receptors and showed GH-induced pY-Stat5 responses, which varied with their state of chondrocyte differentiation. In vivo, Stat5b+ve nuclei were seen in the resting and prehypertrophic chondrocytes of the growth plate. After a single ip pulse of human GH or mouse GH, but not prolactin, pY-Stat5 responses were visible in cells in the resting zone and groove of Ranvier, 10-45 min ...
Growth plates are the areas of new bone growth, usually near the ends of long bones. A growth plate is weaker than solid bone. This makes it more likely to get injured.
Author(s): Wang, Weiguang; Rigueur, Diana; Lyons, Karen M | Abstract: The ligands that comprise the Transforming Growth Factor β superfamily highly govern the development of the embryonic growth plate. Members of this superfamily activate canonical TGFβ and/or BMP (Bone Morphogenetic Protein) signaling pathways. How these pathways interact with one another is an area of active investigation. These two signaling pathways have been described to negatively regulate one another through crosstalk involving Smad proteins, the primary intracellular effectors of canonical signaling. More recently, a mechanism for regulation of the BMP pathway through TGFβ and BMP receptor interactions has been described. Here in this review, we demonstrate examples of how TGFβ is a gatekeeper of BMP action in the developing growth plate at both the receptor and transcriptional levels.
Histone deacetylase (HDAC) inhibitors are efficacious epigenetic-based therapies for some cancers and neurological disorders; however, each of these drugs inhibits multiple HDACs and has detrimental effects on the skeleton. To better understand how HDAC inhibitors affect endochondral bone formation, we conditionally deleted one of their targets, Hdac3, pre- and postnatally in type II collagen α1 (Col2α1)-expressing chondrocytes. Embryonic deletion was lethal, but postnatal deletion of Hdac3 delayed secondary ossification center formation, altered maturation of growth plate chondrocytes, and increased osteoclast activity in the primary spongiosa. HDAC3-deficient chondrocytes exhibited increased expression of cytokine and matrix-degrading genes (Il-6, Mmp3, Mmp13, and Saa3) and a reduced abundance of genes related to extracellular matrix production, bone development, and ossification (Acan, Col2a1, Ihh, and Col10a1). Histone acetylation increased at and near genes that had increased expression. ...
What are growth plate injuries? The growth plate is the area of tissue near the ends of long bones in children and teens that determines what length and shape the bone will be once it is done growing. Each long bone- the thigh bone, the bones in the forearm, and the bones in the hands and fingers-has at least two growth plates, one at each end. Once your child has finished growing, the growth plates close and are replaced by solid bone. The growth plates are weak areas of your childs growing skeleton, making it easier to injure them. ...

TY - JOUR. T1 - Expression of the Ellis-van Creveld (Evc) gene in the rat tibial growth plate. AU - Tsuji, Takehito. AU - Nakamura, Hiroaki. AU - Hirata, Azumi. AU - Yamamoto, Toshio. PY - 2004/8. Y1 - 2004/8. N2 - Ellis-van Creveld (EvC) syndrome is an autosomal recessive chondrodysplasia characterized by short limbs, postaxial polydactyly, natal teeth, and dysplastic nails. The Ellis-van Creveld (EVC) gene, which is mutated in patients with EvC syndrome, has been identified by positional cloning. However, the physiological roles of the EVC gene have not been elucidated. Histopathological analyses of EvC syndrome have shown disturbed chondrocytic phenotypes during cartilage development. We therefore postulated that the EVC gene is a critical factor for chondrocytes during endochondral ossification. The present study focuses on the relationship between the Evc gene and chondrocytes, and examines Evc gene expression in the rat tibial growth plate at the mRNA and protein levels. Evc mRNA in tibial ...
Rickets is a condition of growing children in which there is failure of normal mineralisation of the epiphyseal growth plate. Normal growth plate development is dependent upon a cascade of events that consists of resting chondrocytes becoming preproliferative, proliferative, hypertrophic and finally apoptotic, which is a signal for the invasion of the growth plate by bone-forming cell precursors that replace the apoptosed cartilage cells with bone cells that mineralise the epiphyseal growth plate into true bone. Eventually, the growth plate is obliterated as the metaphyseal and epiphyseal ends of the bones fuse. It is therefore evident that rickets can only occur in growing children in whom the growth plate is still not fused.. The final step of apoptosis is promoted by phosphate which has to be present in sufficient concentration to facilitate apoptosis1. In the absence of enough phosphate, apoptosis does not proceed correctly, the growth plate widens and there is failure of normal invasion of ...

Tibial dyschondroplasia (TD) is a metabolic cartilage disease of young poultry in which endochondral bone formation is disrupted leading to the retention of a non-calcified, avascular plug of cartilage in the tibial growth plate. Chicks aged 7 days were fed either a control diet or one containing thiram 100 ppm for 48 h to induce TD. Cell multiplication in the growth plate was determined thereafter with bromodeoxyuridine (BrdU) labelling, and metabolic changes by measuring alkaline phosphatase (ALP), tartrate-resistant acid phosphatase (TRAP), and glutathione (GSH) activities. The effect on chondrocyte maturation was examined. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) and DNA fragmentation were used to determine the effects of thiram on cell survival. Thiram-induced TD was not due to the multiplication of cells in the post-proliferative zones. Thiram did not affect ALP activity, which would have indicated a loss of calcification potential, but it reduced both ...
Extracellular inorganic phosphate (P(i)) concentrations are the highest in the growth plate just before the onset of mineralization. P(i) not only is required for hydroxyapatite mineral formation but also modulates terminal differentiation and apoptosis of growth plate chondrocytes. Extracellular P(i) stimulated terminal differentiation marker gene expression, including the progressive ankylosis gene (ank), alkaline phosphatase (APase), matrix metalloproteinase-13 (MMP-13), osteocalcin, and runx2, mineralization, and apoptosis of growth plate chondrocytes. The stimulatory effect of extracellular P(i) on terminal differentiation and apoptosis events of growth plate chondrocytes was dependent on the concentration, the expression levels of type III Na(+)/P(i) cotransporters, and ultimately P(i) uptake. A high extracellular P(i) concentration was required for the stimulation of apoptosis, whereas lower P(i) concentrations were required for the most effective stimulation of terminal differentiation ...
I was reading an article today about how a person was able to edit Wikipedia articles to help with his online niche websites and I wanted to try to test this idea.. I have been using Wikipedia as a resource to do research since I was in college and it has been amazingly helpful and useful. It seems that anyone in the world can edit the Wikipedia articles as long as they are really being helpful and trying to create a better resource.. So I created my own Wikipedia account under the username Height_Analyst and did a slight edit on the articles for Low Intensity Pulsed Ultrasound and Epiphyseal Plate. Right after the sentence where it states that Dr. Chen of the University of Alberta thinks that LIPUS can possibly lead to grow taller by stimulating bone growth I added the sentence However it has not been shown to be able to help in bone longitudinal growth when combined with bioengineered cartilage pellets for growth plate induced fractures. I referenced this study from a university in Hong ...
Hypertrophic chondrocytes contained the highest numerical abundance of peroxisomes compared to proliferative chondrocytes as examples for endochondral ossification.
Chondrocytes of the epiphyseal growth zone are regulated by the Indian hedgehog (IHH)-parathyroid hormone-related protein (PTHrP) axis. In weight-bearing joints, this growth zone comes to be subdivided by the secondary ossification center into distinct articular and growth cartilage structures. The purpose of this study was to explore the cells of origin, localization, regulation of expression, and putative functions of IHH and PTHrP in articular cartilage in the mouse. We assessed IHH and PTHrP expression in an allelic PTHrP-LacZ-knockin mouse and several versions of PTHrP-null mice. Selected joints were unloaded surgically to examine load-induction of PTHrP and IHH. The embryonic growth zone appears to serve as the source of PTHrP-expressing proliferative chondrocytes that populate both the forming articular cartilage and growth plate structures. In articular cartilage, these cells take the form of articular chondrocytes in the midzone. In PTHrP
Discussion. Pathologic conditions affecting growth plates can result in severe orthopaedic problems. This case report demonstrates traumatic displacement of an ununited medial condylar ossification centre of the distal humerus in a mature cat. The bilateral symmetry and precise location of the bone fragments suggest a failure of physeal closure of the medial aspect of the distal humeral epiphyseal growth plate with nonunion of the medial condylar ossification centre. ►Fig. 5 demonstrates the radiographic appearance of the medial condylar ossification centre in a normal 8-week-old kitten. The humeral condyle arises from two separate ossification centres. The lateral ossification centre is the first to form, and in the cat it is radiographically apparent from 2 weeks of age and themedial centre from3 weeks of age.12 Physeal closure with union of the lateral and medial condylar centres is expected by 18weeks of age.2 A failure of physeal closure and nonunion of the medial condylar ossification ...
The above photo is of the heel bone in a 12 year old boy. The heel bone is called the calcaneus and has an important growth plate at the base. Boys from 8 to 14 and Girls 7 to 13 can have pain develop in this area either from the pull of the achilles tendon, or the pull of the plantar fascia. After those ages, the growth plates fuse and there can no longer be a source of pain. With my 2 boys growing up, and playing tons of sports, both had this problem. Ice soaking (see separate post) for 20 minutes twice daily really minimizes the soreness, but you must start as soon as the soreness begins. At least they could just dip their heel into the ice water, not the entire foot. We always joked as they iced that they were now guaranteed to grow more ...

Chondrogenesis occurs via three steps: (a) commitment to chondrocyte differentiation by mesenchymal cells, seen as mesenchymal condensation; (b) chondrocyte proliferation in the growth plate to facilitate longitudinal development; and (c) differentiation of proliferating chondrocytes to hypertrophic chondrocytes (for review see references 1, 2). During endochondral ossification, chondrocyte hypertrophy is critical, because cells alter the extracellular matrix and induce vascular invasion. Extrinsic factors such as bone morphogenetic proteins, Indian hedgehog, and modulators such as Sox9, Runx2, Smads, and histone deacetylase 4 are reportedly essential for chondrogenesis (1, 2). Loss of histone deacetylase 4 causes early onset of hypertrophy, followed by growth retardation (6). Overexpression of Runx2 under the control of a type II collagen promoter/enhancer induces dwarfism because of precocious endochondral ossification and accelerated chondrocyte differentiation (4, 5). Thus, regulation of ...
Treatment revolves around decreasing activity. Usual treatment has been putting children in a boot in slight equinus, or a cast with the foot in slight equinus, thereby decreasing the tension on the heel cord, which in turn pulls on the growth plate at the heel. As the pain resolves, children are allowed to go back to full activities. Complete resolution may be delayed until growth of the foot is complete (when the growth plate fuses to the rest of the bone of the heel). A soft cushioning heel raise is really important (this reduces the pull from the calf muscles on the growth plate and increases the shock absorption, so the growth plate is not knocked around as much). The use of an ice pack after activity for 20mins is often useful for calcaneal apophysitis, this should be repeated 2 to 3 times a day. As a pronated foot is common in children with this problem, a discussion regarding the use of long term foot orthotics may be important. If the symptoms are bad enough and are not responding to ...
Estrogen is essential for the development and maintenance of optimal bone mass in women and men, and acts through activation of estrogen receptors (ER). We have examined the pathways of estrogen action on the skeleton by seeking to localize the classical estrogen receptor, ER alpha, to particular cells to test the hypotheses that 1) estrogen directly influences growth plate chondrocytes; and 2) estrogen has a principal action on bone tissue via osteoblasts. ER alpha messenger ribonucleic acid (mRNA) was localized by in situ hybridization in human specimens from five males (11-15 yr old), two females (9 and 11 yr old), and three growing rabbits. In all of the human material examined, ER alpha mRNA was consistently identified in chondrocytes. In all of the rabbit tissue studied, ER alpha mRNA was localized in chondrocytes of the growth plate and the subarticular epiphyseal growth center. ER alpha mRNA signals were readily observed in both active osteoblasts and lining cells on trabecular surfaces of all

Limitations associated with demineralised bone matrix and other grafting materials have motivated the development of alternative strategies to enhance the repair of large bone defects. The growth plate (GP) of developing limbs contain a plethora of growth factors and matrix cues which contribute to long bone growth, suggesting that biomaterials derived from its extracellular matrix (ECM) may be uniquely suited to promoting bone regeneration. The goal of this study was to generate porous scaffolds from decellularised GP ECM and to evaluate their ability to enhance host mediated bone regeneration following their implantation into critically-sized rat cranial defects. The scaffolds were first assessed by culturing with primary human macrophages, which demonstrated that decellularisation resulted in reduced IL-1β and IL-8 production. In vitro, GP derived scaffolds were found capable of supporting osteogenesis of mesenchymal stem cells via either an intramembranous or an endochondral pathway, demonstrating
Medial Epicondyle Apophyseal Injuries: The growth plate in the bone on the inside aspect of the elbow (that is, the part of the elbow near the hip when your arm is by your side) can be a significant source of pain in the baseball thrower. The growth plate injury may involve isolated pain with no fracture (epiphysiolysis) or fracture with or without displacement.. Epiphysiolysis (i.e., Youth Throwing Elbow Syndrome): When the arm is overworked and/or over-stressed, the growth plate may become painful. This pain can be a warning sign for possible future fracture. In this situation, non-surgical treatment with rest from throwing and a guided physical therapy plan can be critical in preventing more significant injury and allow for eventual return to play.. Medial Epicondyle Avulsion Fracture: When the growth plate is overworked or overstressed, the growth plate may eventually fracture. Depending upon the displacement of the fracture, non-surgical or surgical treatment will be required.. Ulnar ...

NOS isoform expression and NO adducts in chick growth cartilage were detected by immunohistochemistry and Western blot analysis. All NOS isoforms were expressed in chick growth plate chondrocytes with the highest levels present in the hypertrophic region. The enzymes were active since nitrosocysteine and nitrotyrosine residues were detected in regions of the epiphysis with the highest levels of NOS expression. Maturing chick sternal chondrocytes evidenced an increase in NO release and a rise in NOS protein levels. When treated with NOS inhibitors, there was a ...
Anatomically, Eusthenopteron shares many unique features in common with the earliest known tetrapods. It shares a similar pattern of skull roofing bones with forms such as Ichthyostega and Acanthostega. Eusthenopteron, like other tetrapodomorph fishes, had internal nostrils, (or a choana) which are one of the defining traits of tetrapodomorphs (including tetrapods). It also had labyrinthodont teeth, characterized by infolded enamel, which characterizes all of the earliest known tetrapods as well. Like other fish-like sarcopterygians, Eusthenopteron possessed a two-part cranium, which hinged at mid-length along an intracranial joint. Eusthenopterons notoriety comes from the pattern of its fin endoskeleton, which bears a distinct humerus, ulna, and radius (in the fore-fin) and femur, tibia, and fibula (in the pelvic fin). These appendicular long bones had epiphyseal growth plates that allowed substantial longitudinal growth through endochondral ossification, as in tetrapod long bones.[4] These ...
2) microscopic appearance. Early microscopic lesions are those of acute inflammation in which the intertrabecular tissue of the primary spongiosa is infiltrated with large numbers of neutrophils (fig. Ic-45). Inflammation results in necrosis of osteoblast and osteoclasts lining trabeculae of the primary spongiosa, and necrosis of osteoblasts leads to failure of ossifications of mineralized cartilaginous trabeculae. Some of these mineralized cartilaginous trabeculae that are thin and elongated may fracture and cause an infraction (incomplete fracture) beneath the physeal plate (figs. Ic-46, Ic-47). Damage to the metaphyseal vessels prevents normal physeal plate cartilage resorption and leads to increased depth of the zone of mineralized hypertrophic cartilage. Inflammation of osteochondral junctions (osteochondritis) may be present despite the absence of gross or radiographic lesions. Osteomyelitis may be evident in the mandible, particularly in the dental sac, and the incisor and molar teeth may ...

Although the name might sound pretty frightening, Severs disease is really a common heel injury that occurs in kids. It can be painful, but is only temporary and has no long-term effects. Severs disease, also called calcaneal apophysitis, is a painful bone disorder that results from inflammation (swelling) of the growth plate in the heel. A growth plate, also called an epiphyseal plate, is an area at the end of a developing bone where cartilage cells change over time into bone cells. As this occurs, the growth plates expand and unite, which is how bones grow. Severs disease is a common cause of heel pain in growing kids, especially those who are physically active. It usually occurs during the growth spurt of adolescence, the approximately 2-year period in early puberty when kids grow most rapidly. This growth spurt can begin any time between the ages of 8 and 13 for girls and 10 and 15 for boys. Severs disease rarely occurs in older teens because the back of the heel usually finishes growing ...

Growth hormone is secreted in pulses, with an average interpulse interval of 2-3 hours, with the most reproducible peak occurring at the onset of sleep. Complete absence of GH slows the rate of growth to only one third to one half of normal. Abnormally elevated levels lead to gigantism. In the adult patient with GH excess, no effects are seen in the long bones after the epiphyseal growth plates have fused. Instead, GH excess gradually produces acromegaly, a coarse thickening of the bones of the skull, hands and feet over the course of years to decades ...
Epiphyseal fractures are fractures that involve the epiphyseal growth plate in children and teenagers. Classificaton by Salter and Harris that was published in 1963 divides them into five types. It is a modification of previous classifications by Poland (1898) and Aitken (1936). Later, several other rare types of epiphyseal fractures were appended by other authors. Epiphyseal fractures may result in growth disturbances. A mnemonic SALTR can aid in memorizing the types for the purporses of examination.. ...

Citation: N/A Interpretive Summary: Technical Abstract: The effect of continuous vs pulsatile cGH administration on tissue IGF-1 protein and IGF-1 mRNA levels were examined in 8 wk old meat-type chickens. Birds were infused via infusion pumps with either cGH or saline. In both regimes the birds received 123 ug/kg bwt/day. IGF-1 protein concentration (pg/mg protein) were determined by RIA and the relative levels of IGF-1 mRNA by a solution hybridization nuclease protection assay in liver, kidney, spleen, heart, muscle (gastrocnemius and pectoralis major) and growth plate cartilage. Continuous infusion elicited a two fold increase in IGF-1 concentrations in the kidney, while all other tissue concentrations were not altered. Pulsatile infusion caused a two-fold increase in IGF-1 concentrations in the liver, gastrocnemius and pectoralis muscles. IGF-1 levels in other tissues surveyed remained unchanged. With continuous infusion there was a 2-fold increase in the levels of IGF-1 mRNA in the liver and ...

To test the hypothesis that Lmx1 genes have overlapping functions in the development of the hindbrain roof plate, we compared the embryonic roof plate phenotypes of Lmx1a−/−, Lmx1b−/−, and Lmx1a−/−; Lmx1b−/− mice. We showed that roof plate development is largely normal in Lmx1b−/− mutants, indicating no unique role for Lmx1b in hindbrain roof plate development. However, we observed complete deletion of the hindbrain roof plate in Lmx1a−/−; Lmx1b−/− double-null mutants. This conclusion is based not only on loss of all roof plate markers in double-null embryos, but also our demonstration that there is complete loss of roof plate function in these embryos. No induction of Math1, a marker of rhombic lip, occurs. Our data therefore provides genetic proof that Lmx1b function is overlapping to Lmx1a in roof plate development.. Lmx1b is expressed in the IsO, where it is required to maintain the IsO, an important anterior-posterior signaling center at the mid/hindbrain ...
