Oral sensory papillae, chemo- and mechano-receptors, in the snake, Elaphe quadrivirgata. A light and electron microscopic study. (1/52)

The oral sensory papillae of the snake (Elaphe quadrivirgata), comprising a compound sensory system located along the tooth rows, were studied by light microscopy, immunohistochemistry for neuron specific enolase and S 100 protein, and scanning and transmission electron microscopy. Each sensory papilla exhibited a single taste bud and free nerve endings in the epithelium, and Meissner-like corpuscles, branched coiled terminals, and lamellated corpuscles in the connective tissue. The taste buds consisted of four types of cells; the type III cells, exclusively synapsing onto intragemmal nerves, were identified as gustatory in function. The gustatory cells included dense-cored and clear vesicles in the cytoplasm. These vesicles were accumulated both in the presynaptic and infranuclear regions, suggesting dual functions: the synaptocrine and paracrine/endocrine release of signal substances. The free nerve endings constantly contained mitochondria and frequent clear vesicles. The Meissner-like corpuscles were located in the uppermost zone of the connective tissue. These corpuscles consisted of nerve fibers and lamellar cells. The nerve fibers, rich in mitochondria, were folded and layered on each other. The branched coiled terminals were localized in the connective tissue along the side wall of the papillae. Nerve fibers, free from a Schwann-cell covering, swelled up to make terminals which accumulated mitochondria and glycogen particles. The lamellated corpuscles were associated with the nerve-fiber bundles in the connective tissue. Consisting of a central nerve axon and lamellar cells encircling it, these corpuscles resembled mammalian Vater-Pacini corpuscles, except that they lacked a capsule. These findings demonstrated that the snake sensory papilla represents one of the most specialized, compound sensory systems among vertebrates, which may play an important role in receiving chemical and mechanical information on prey.  (+info)

Widespread expression of tartrate-resistant acid phosphatase (Acp 5) in the mouse embryo. (2/52)

Tartrate-resistant acid phosphatase (TRAP, Acp 5) is considered to be a marker of the osteoclast and studies using 'knockout' mice have demonstrated that TRAP is critical for normal development of the skeleton. To investigate the distribution of TRAP in the mammalian embryo, cryostat sections of 18 d murine fetuses were examined by in situ hybridisation, immunohistochemistry and histochemical reactions in situ. Abundant expression of TRAP mRNA was observed in the skin and epithelial surfaces of the tongue, oropharynx and gastrointestinal tract including the colon, as well as the thymus, ossifying skeleton and dental papillae. TRAP protein was identified at the same sites, but the level of expression in the different tissues did not always correlate with apparent enzyme activity. The findings indicate that abundant TRAP expression is not confined to osteoclasts in bone, but occurs in diverse tissues harbouring cells of bone marrow origin, including dendritic cells and other cells belonging to the osteoclast/macrophage lineage.  (+info)

Dissection of the odontoblast differentiation process in vitro by a combination of FGF1, FGF2, and TGFbeta1. (3/52)

Dental papillae (DP) isolated from first lower molars of 17-day-old mouse embryos were cultured in the presence of combinations of the following growth factors: FGF1, FGF2, and TGFbeta1. After 6 days in culture, only the DP treated with FGF1+TGFbeta1 contained differentiated odontoblast-like cells at the periphery of the explants, and these cells secreted extracellular matrix similar to predentin. Surprisingly, treatments with FGF2+TGFbeta1 induced cell polarization at the surface of the explants but no matrix secretion was observed. Electron microscopy and histochemical analysis of odontoblast markers showed that differentiated cells induced by FGF1+TGFbeta1 exhibited cytological features of functional odontoblasts with matrix vesicle secretion and mineral formation, positive alkaline-phosphatase activity, and type-I collagen production. DP cultured in the presence of FGF2+TGFbeta1 showed cell polarization and long and thin cell processes containing matrix vesicles; however, type-I collagen secretion was not detected and alkaline-phosphatase activity was completely inhibited. Our results indicate that, in our culture system, exogenous combinations of FGF1, FGF2, and TGFbeta1 interact with preodontoblasts and induce cell polarization or differentiation, which can be studied separately in vitro. Thus, FGF1 and TGFbeta1 do have a synergic effect to promote morphological and functional features of differentiated odontoblasts whereas FGF2 seems to modulate TGFbeta1 action, causing morphological polarization of preodontoblasts but limiting the functional activity of these cells in terms of type-I collagen secretion and alkaline-phosphatase activity.  (+info)

Development and maturation of taste buds of the palatal epithelium of the rat: histological and immunohistochemical study. (4/52)

Palatal taste buds are intriguing partners in the mediation of taste behavior and their spatial distribution is functionally important for suckling behavior, especially in the neonatal life. Their prenatal development has not been previously elucidated in the rat, and the onset of their maturation remains rather controversial. We delineated the development and frequency distribution of the taste buds as well as the immunohistochemical expression of alpha-gustducin, a G protein closely related to the transduction of taste stimuli, in the nasoincisor papilla (NIP) and soft palate (SP) from the embryonic day 17 (E17) till the postnatal day 70 (PN70). The main findings in the present study were the development of a substantial number of taste pores in the SP of fetal rats (60.3 +/- 1.7 out of 122.8 +/- 5.5; mean +/- SD/animal at E19) and NIP of neonatal rats (9.8 +/- 1.0 out of 44.8 +/- 2.2 at PN4). alpha-gustducin-like immunoreactivity (-LI) was not expressed in the pored taste buds of either prenatal or newborn rats. The earliest expression of alpha-gustducin-LI was demonstrated at PN1 in the SP (1.5 +/- 0.5 cells/taste bud; mean +/- SD) and at PN4 in the NIP (1.4 +/- 0.5). By age the total counts of pored taste buds continuously increased and their morphological features became quite discernible. They became pear in shape, characterized by distinct pores, long subporal space, and longitudinally oriented cells. Around the second week, a remarkable transient decrease in the total number of taste buds was recorded in the oral epithelium of NIP and SP, which might be correlated with the changes of ingestive behaviors. The total counts of cells showing alpha-gustducin-LI per taste bud gradually increased till the end of our investigation (14.1 +/- 2.7 in NIP and 12.4 +/- 2.5 in SP at PN70). We conclude that substantial development of taste buds began prenatally in the SP, whereas most developed entirely postnatal in the NIP. The present study provides evidence that the existence of a taste pore which is considered an important criterion for the morphological maturation of taste buds is not enough for the onset of the taste transduction, which necessitates also mature taste cells. Moreover, the earlier maturation of palatal taste buds compared with the contiguous populations in the oral cavity evokes an evidence of their significant role in the transmission of gustatory information, especially in the early life of rat.  (+info)

The whereabouts of a morphogen: direct evidence for short- and graded long-range activity of hedgehog signaling peptides. (5/52)

Sonic Hedgehog (Shh) and Indian Hedgehog (Ihh) are members of the Hedgehog (Hh) family of signaling molecules known to be involved in embryonic patterning and morphogenesis. The Hh proteins undergo an autocatalytic cleavage to yield an N-terminal and a C-terminal peptide, with the signaling capacities confined to the N peptide. Drosophila Hh-N has been shown to act via both short- and long-range signaling. In vertebrates, however, attempts to directly demonstrate Shh (SHH) or Ihh (IHH) proteins at a distance from producing cells have been largely unsuccessful. Furthermore, the fact that the Hh N peptides occur in a cholesterol-modified, membrane-tethered form is not easily reconciled with long-range signaling. This study used optimized immunohistochemistry combined with tissue separation and biochemical analyses in vivo and in vitro to determine the range of action of SHH and IHH in the mouse embryo. In all embryonic structures studied, we detect signaling peptides in producing cells, but we also find that ligands move over considerable distances depending on the tissue. These data provide direct evidence for the presence of Hedgehog signaling peptides in target compartments, suggesting a direct long-range action without a need for secondary mediators. Visualization of Hedgehog proteins in target tissues was achieved only under conditions that allowed proteoglycan/glycosaminoglycan (PG/GAG) preservation. Furthermore, we show that induced changes of the composition of PG/GAG in the tooth alter SHH signaling. These data suggest a crucial role for PG/GAGs in Hedgehog movement.  (+info)

Slit1 is specifically expressed in the primary and secondary enamel knots during molar tooth cusp formation. (6/52)

The shape and diversity of the mammalian molar teeth is suggested to be regulated by the primary and secondary enamel knots, which are putative epithelial signaling centers of the tooth. In search of novel molecules involved in tooth morphogenesis, we analyzed mRNA expression of Slit1, -2 and -3, earlier characterized as secreted signals needed for axonal pathfinding and their two receptors Robo1 and -2 (Roundabout1 and -2) in the developing mouse first molar. In situ hybridization analysis showed that Slit1 mRNAs were expressed in the primary enamel knot of the bud and cap stage tooth germ and later the expression continued in the secondary enamel knots of the late cap and bell stage tooth. In contrast, expression of Slit2 and -3 as well Robo1, and -2 was largely restricted to mesenchymal tissue components of the tooth until the bell stage. At the late bud stage, however, Robo1 transcripts were evident in the primary enamel knot, and at the cap stage a pronounced expression was noted in the middle of the tooth germ covering the primary enamel knot and dental papilla mesenchyme. During the bell stage, Robo1 and Slit2 expression became restricted to the dental epithelia, while Slit3 continued in the dental mesenchyme. Prior to birth, Robo1 and -2 were co-localized in the predontoblasts. These results indicate that Slits and Robos display distinct, developmentally regulated expression patterns during tooth morphogenesis. In addition, our results show that Slit1 is the second known gene specifically located in the primary and secondary enamel knots.  (+info)

Induction and regulation of crown dentinogenesis: embryonic events as a template for dental tissue repair? (7/52)

Close regulation of odontoblast differentiation and subsequent secretory activity is critical for dentinogenesis during both embryogenesis and tissue repair. Some dental papilla cells achieve commitment and specific competence, allowing them to respond to epithelially derived inductive signals during the process of odontoblast differentiation. Temporo-spatial regulation of odontoblast differentiation is dependent on matrix-mediated interactions involving the basement membrane (BM). Experimental studies have highlighted the possible roles of growth factors in these processes. Regulation of functional activity of odontoblasts allows for both ordered secretion of the primary dentin matrix and maintenance of vitality and down-regulation of secretory activity throughout secondary dentinogenesis. After injury to the mature tooth, the fate of the odontoblast can vary according to the intensity of the injury. Milder injury can result in up-regulation of functional activity leading to focal secretion of a reactionary dentin matrix, while greater injury can lead to odontoblast cell death. Induction of differentiation of a new generation of odontoblast-like cells can then lead to reparative dentinogenesis. Many similarities exist between development and repair, including matrix-mediation of the cellular processes and the apparent involvement of growth factors as signaling molecules despite the absence of epithelium during repair. While some of the molecular mediators appear to be common to these processes, the close regulation of primary dentinogenesis may be less ordered during tertiary dentinogenic responses.  (+info)

The influence of the distance from the contact point to the crest of bone on the presence of the interproximal dental papilla. (8/52)

BACKGROUND: Loss of the interproximal dental papilla may cause functional and, especially in the maxillary anterior region, phonetic and severe esthetic problems. The purpose of this study was to investigate whether the distance from the contact point to the bone crest on standardized periapical radiographs of the maxillary anterior teeth could be correlated with the presence of the interproximal papilla in Taiwanese patients. METHODS: In total, 200 interproximal sites of maxillary anterior teeth in 45 randomly selected patients were examined. Selected subjects were adult Taiwanese with fully erupted permanent dentition. The presence of the interproximal papilla was determined visually. If there was no visible space apical to the contact area, the papilla was recorded as being present. The distance from the contact point to the crest of bone was measured on standardized periapical radiographs using a paralleling technique with a RinnXCP holder. RESULTS: Data revealed that when the distance from the contact point to the bone crest on standardized periapical radiographs was 5 mm or less, the papillae were almost 100% present. When the distance was 6 mm, 51% of the papillae were present, and when the distance was 7 mm or greater, only 23% of the papillae were present. CONCLUSION: The distance from the contact point to the bone crest on standardized periapical radiographs of the maxillary anterior teeth is highly associated with the presence or absence of the interproximal papilla in Taiwanese patients, and is a useful guide for clinical evaluation.  (+info)

Cells of the inner enamel epithelium located adjacent to the dental papilla mesenchymal cells, differentiate into early ameloblasts during the bell stage. Early ameloblasts differentiate into mature cells through pre-secretory and secretory stages. During the pre-secretory stage, the early ameloblasts differentiate and initiate synthesis of the enamel-related proteins. In the secretory stage, the matrix proteins accumulate extracellularly and the tooth crown is formed ...
Full papillae serve both esthetic and functional roles. Black triangles have perplexed clinicians by interrupting the harmony of the smile. Several studies in the past have attempted to understand the appearance of black triangles. Bone to contact distance is the most discussed factor involved in black triangle appearance, but there seems to be countless others. Newer research has focused on systemic as well as local anatomical factors such as age, interdental width, and tissue thickness. The aim of this study was to evaluate papilla fullness with regards to bone to contact distance, interdental width, periodontal biotype, tooth type, and age. ❧ 333 papillae from 50 patients of the dental hygiene department of the Herman Ostrow School of Dentistry of the University of Southern California were examined. The age of each patient was recorded. After adequate anesthesia, each sextant was examined for papilla fullness. Periodontal sounding was used to measure both the bone to contact distance and ...
Gingival squamous cell carcinoma (GSCC) is mainly observed as an exophytic mass with a verrucous or papillary surface with red or mixed red and white color (32). GSCC can sometimes mimic severe periodontal disease with symptoms such as swelling, gingival bleeding, tooth mobility, deep pocket depth and bone loss (33). Some manifestations of GSCC which are sometimes similar to periodontal inflammatory lesions are introduced:. 1- A single red epulis-like lesion in dental papilla of the tooth #22. It bled with minor provocation and the probing depth reached seven millimeters. There was no bone invasion radiographically. Dental papilla is a rare site for GSCC (34).. 2- There were some case reports of GSCC mimicking dento-alveolar abscess. It was reported as an erythematous papule located within the attached gingiva of the teeth #9 and #10 near mucogingival junction. It had a soft spongy texture. Oozing was observed from a little hole on the lesion. No periodontal pocket, no mobility, bone loss, root ...
Two studies in this issue demonstrate how data from emergency care can be used to inform public health interventions. Acute and chronic alcohol intoxication, a worrying global public health issue, is the cause of many health and social problems. Reunion Island in the South West Indian ocean is no exception. Reunion Island is among the four French regions where premature mortality due to alcoholism and cirrhosis is the highest and foetal alcohol syndrome is seven times higher than that of metropolitan France. Vilain and colleagues undertook an exploratory analysis based on syndromic surveillance data to describe the emergency department visits for alcohol intoxication and factors associated with their variation. Alcohol intoxication attendances were the second most common reason for ED attendances after trauma and these attendances increased significantly on benefit payday, weekends and public holidays. The authors conclude this kind of syndromic surveillance system for monitoring public health ...
Your veterinarian will perform a thorough physical and oral exam on your dog, taking into account the background history of symptoms, if there have been any. Dens-in-dente, an anomaly of development resulting from the deepening of enamel into the dental papilla (the cells involved in the developing tooth), typically begins at the crown and often extends to the root before the calcification of the dental tissues takes place. Traumatic damage to the tooth, possibly from aggressive deciduous tooth (i.e., baby tooth) extraction, may be linked to a loss of dental integrity.. If your veterinarian finds that the tooth is too damaged to remain, an assessment of the remaining mandibular bone will be an important prior to an extraction attempt. The diagnostic evaluation will include taking a dental X-ray to evaluate the extent of the changes, particularly at the roots.. ...

So, how do babys teeth grow ? The baby teeth actually starts growing during the 6th week in the mothers uterus. These baby teeth growth starts with the Bell shape tooth germ. This Bell shape structure seen is actually the enamel organ, which will eventually grow into a baby teeth. As you can see the enamel organ or tooth germ contains numerous cells. These cells will continue to grow and differentiate into different and more advance cells to form the tooth. The outer and inner enamel organ eventually forms the outer casing of the tooth called the enamel layer. Where else the dental papilla cells will form the inner section of the tooth known as the pulp chamber. The permanent tooth bud will continue to grow into the permanent teeth after the baby tooth eruption is completed in the mouth.. ...

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open apices. It encourages a longer and thicker root to develop thus decreasing the propensity of long term root fracture. This case report highlights the role of Hertwig root sheath and dental papilla in continued root formation of immature permanent tooth, even diagnosed with necrotic pulp.

Magnetic resonance imaging findings in Axenfeld–Rieger syndrome Matthew T Whitehead,1,2 Asim F Choudhri,1,2 Sarwat Salim31Department of Radiology, University of Tennessee Health Science Center, Memphis, TN, USA; 2Le Bonheur Neuroscience Institute, Le Bonheur Children’s Hospital, Memphis, TN, USA; 3Department of Ophthalmology, University of Tennessee Health Science Center, Memphis, TN, USAAbstract: Axenfeld–Rieger syndrome (ARS) is a genetic disorder representing a disease spectrum resulting from neural crest cell maldevelopment. Glaucoma is a common complication from the incomplete formation of the iridocorneal angle structures. Neural crest cells also form structures of the forebrain and pituitary gland, dental papillae, aortic arch walls, genitalia, and long bones; therefore, patients with ARS manifest a wide range of systemic findings. To our knowledge, detailed magnetic resonance imaging findings have not been previously reported. We report a case of a 19-month-old Indian male
Tooth regeneration: A stem cell based regenerative medicine procedure to replace damaged or lost teeth by regrowing them from autologous stem cells ...
The human body is a unique template, but it shares some commonalities from one individual to the next. For instance, everyone has papillae on their tongue. The majority of individuals will never experience any type of problem from this, but others will. These circular bumps are found throughout the surface of the tongue and they perform a variety of different functions. When they work together, they give you the ability to taste different foods. Below, you will learn about these, as well as the problematic condition known as enlarged papillae. Four Types Of Papillae First, you should take the time to familiarize yourself with the different types of papillae. There are actually four of them and theyll be explored in more depth below. Circumvallate: These are found at the back of the tongue and they form a V. Theyre responsible for identifying bitter tastes. Foliate: These are located on the sides of the tongue. There are two accumulations of foliate papillae. Filiform: These also form a V shape. They

DOI: 10.11607/prd.00.0224 An index to assess the size of the interproximal gingival papillae adjacent to single implant restorations was described and preliminary tested in a pilot study of retrospective material comprising 25 crowns in 21 patients. The result indicated a significant spontaneous regeneration of papillae (P < .001) after a mean follow-up period of 1.5 years. Based on these results, the general conclusion was made that the proposed index allows scientific assessment of soft tissue contour adjacent to single-implant restorations. The results also indicated that soft tissue changed in a systematic manner during the ti me period between insertion of the crowns and follow-up 1 to 3 years later ...

The potential from dental pulp stem cells include developing nerve and brain tissue, repairing muscle, developing bone, developing bone and tissue from the oral cavity, reconstructing affected cardiac tissue, developing cartilage, and treating type 1 diabetes to name a few. In the past, researchers harvested stem cells taken from bone marrow to create cells of various organs, however years of research implies that dental stem cells extracted from a tooth pulp might build organ tissues more quickly. Of major relevance is that UK scientists have ascertained that stem cells derived from tooth pulp effectively prevent a leading cause of blindness caused by traumatic injuries or degenerative diseases as reported in a July 2014 study on Neural Regeneration Research (Vol. 9, No. 6, 2014), University Of Birmingham, UK ...
Traumatic injuries to the spinal cord (SCI) and peripheral nerve (PNI) affect several thousand people worldwide every year. At present, there is no effective treatment for SCI and despite continuous improvements in microsurgical reconstructive techniques for PNI, many patients are still left with permanent, devastating neurological dysfunction. This thesis investigates the effects of mesenchymal stem cells (MSC) derived from adipose (ASC) and dental (DSC) tissue and chitosan/microRNA-124 polyplex particles on regeneration after spinal cord and peripheral nerve injury in adult rats. Dental stem cells were obtained from apical papilla, dental pulp, and periodontal ligament. ASC and DSC expressed MSC surface markers (CD73, CD90, CD105 and CD146) and various neurotrophic molecules including BDNF, GDNF, NGF, VEGF-A and angiopoietin-1. Growth factor stimulation of the stem cells resulted in increased secretion of these proteins. Both ASC and DSC supported in vitro neurite outgrowth and in contrast to ...

The elongated papillae trap normal debris, bacteria and other organisms and as the bacteria multiply it produces a dark black, yellow or brown area on your tongue. The elongated papillae with this black color look hairy or furry. This condition is neither an infection nor a cancer and this can be compared to a moss growing on a rock. This condition normally does not occur on people who are healthy ...
Dental pulp stem cells (DPSCs) are stem cells present in the dental pulp, the soft living tissue within teeth. They are multipotent, so they have the potential to differentiate into a variety of cell types. Other sources of dental stem cells are the dental follicle and the developed periodontal ligament. A subpopulation of dental pulp stem cells has been described as human immature dental pulp stem cells (IDPSC). There are various studies where the importance of these cells and their regenerative capacity has been demonstrated. Through the addition of tissue-specific cytokines, differentiated cells were obtained in vitro from these cells, not only of mesenchymal linage but also of endodermal and ectodermal linage. Among them are the IPS, MAPCs cells.[citation needed] Several publications have stressed the importance of the expression of pluripotentiality associated markers: the transcription factors Nanog, SOX2, Oct3/4, SSEA4, CD13, are indispensable for the stem cells to divide indefinitely ...

Thus, to clarify the behavior of cells in an appropriate experimental model, we evaluated the characteristic of MDPC-23 cells and KUSA/A1 cells in vitro and in vivo seeded in diffusion chamber. Our results indicated that KUSA/A1 cells differentiated into osteoblast-like cells and induced bone tissue inside the chamber. Whereas, MDPC-23 cells were odontoblast-like cells but with low ability to induce dentin formation. This study suggests that MDPC-23 cells are special cells, which possess morphological and functional character of odontoblast-like cells, expressing DSPP only in vivo ...
Posted on 05/18/2013 2:08:28 PM PDT by LibWhacker. An international team of scientists led by Prof Cheng-Ming Chuong from the University of Southern California has discovered unique cellular and molecular mechanisms behind tooth renewal in American alligators (Alligator mississippiensis).. Their findings, published in the Proceedings of the National Academy of Sciences, pave the way for tooth regeneration in people. Humans naturally only have two sets of teeth baby teeth and adult teeth. Ultimately, we want to identify stem cells that can be used as a resource to stimulate tooth renewal in adult humans who have lost teeth. But, to do that, we must first understand how they renew in other animals and why they stop in people, Prof Chuong said. Whereas most vertebrates can replace teeth throughout their lives, human teeth are naturally replaced only once, despite the lingering presence of a band of epithelial tissue called the dental lamina, which is crucial to tooth development. Because alligators ...

A microscopic image of tissue invagination into the tooth after 45 days of implantation.. Dental pulp is a complex bundle of tissue, blood vessels and nerves. The tissue dies when it is contaminated by bacteria. During a root canal, a dentist will dig out that contaminated tissue and replace it with an artificial material, Silva said, because you cant leave an open space for bacteria to continue to grow. Even so, root canal therapy treated teeth are destined to be brittle and devitalized.. But what if there was a way to revitalize the tissue and make the tooth healthy again?. While pondering ways to promote root formation, Silva and his team came up with the idea of using stem cells retrieved from the root area deep inside the tooth called the apical papilla. Since they also needed some sort of scaffold for the cells, they devised one made of a polymer fiber impregnated with a protein called vascular endothelial growth factor (VEGF), to stimulate the growth of new blood vessels that would help ...

(
  • In this study, we compared the osteogenic ability of jawbone MSC (JB-MSC) with MSC from tissues with neural crest origin, namely, the dental pulp, apical papilla and periodontal ligament. (
  • The periodontium, including the gingiva, the periodontal ligament, the cementum and the partial alveolar bone, derives from the dental follicle (DF), except for the gingiva. (
  • Some studies have found that HERS could facilitate the cementogenic/osteogenic differentiation of periodontal ligament stem cells, which are the daughter cells of the dental follicle progenitor cells [ 5 ]. (

  • We detected LRCs exclusively on the lingual side of the dental lamina, which exhibits low proliferation rates and is not involved in tooth morphogenesis. (
  • We suggest that the LRCs in the lingual dental lamina represent a population of stem cells, the immediate descendents of which form the successional lamina and, ultimately, the replacement teeth in the gecko. (
  • Furthermore, their location on the non-tooth-forming side of the dental lamina implies that dental stem cells are sequestered from signals that might otherwise induce them to differentiate. (
  • We present pulse-chase and gene expression data that imply that the gecko dental lamina houses cells that resemble mammalian adult stem cells in terms of cell cycling, gene expression and molecular regulation. (
