Spatial and temporal expression of parathyroid hormone-related protein during wound healing. (1/330)

Parathyroid hormone-related protein is produced by many normal tissues including the skin, where it regulates growth and differentiation of keratinocytes. To define better the role of parathyroid hormone-related protein in the skin, we investigated the spatial and temporal expression of parathyroid hormone-related protein and mRNA by immunohistochemistry and in situ hybridization during the healing of skin wounds, and the effects of topical administration of a parathyroid hormone-related protein agonist [parathyroid hormone-related protein (1-36)] and a parathyroid hormone-related protein antagonist [parathyroid hormone (7-34)] on the healing rate and morphology of the wounds. Wounds were produced on the back of guinea pigs with a 4 mm punch, and wound sites were collected at different time points during the healing process. Parathyroid hormone-related protein was expressed in normal skin by all viable keratinocyte layers, hair follicles, and adnexae. Following injury, migratory keratinocytes at wound margins and the newly restored epidermis expressed increased levels of parathyroid hormone-related protein. The remodeling phase was associated with progressive restoration of the pattern of parathyroid hormone-related protein expression in normal epidermis. Granulation tissue myofibroblasts and infiltrating macrophages also expressed parathyroid hormone-related protein. In vitro studies using THP-1 cells (a promonocytic cell line) confirmed that macrophages expressed parathyroid hormone-related protein, especially after activation. Topical application of parathyroid hormone related protein (1-36) or parathyroid hormone (7-34) did not result in significant changes in the healing rate and morphology of the wounds. These findings demonstrated that, in addition to keratinocytes, myofibroblasts and macrophages also represent sources of parathyroid hormone-related protein during the healing of skin wounds. Although the data suggest a role for parathyroid hormone-related protein in the healing of skin and in the restoration of epidermal homeostasis, parathyroid hormone-related protein does not appear to be required for proper re-epithelialization in response to injury, potentially because of redundancy in epidermal growth and wound healing, as has been shown for other paracrine and autocrine growth factors of the epidermis.  (+info)

Chimera analysis reveals that fibroblasts and endothelial cells require platelet-derived growth factor receptorbeta expression for participation in reactive connective tissue formation in adults but not during development. (2/330)

The hypothesis that platelet-derived growth factor (PDGF) plays an important role in repair of connective tissue has been difficult to test experimentally, in part because the disruption of any of the PDGF ligand and receptor genes is embryonic lethal. We have developed a method that circumvents the embryonic lethality of the PDGF receptor (R)beta-/- genotype and minimizes the tendency of compensatory processes to mask the phenotype of gene disruption by comparing the behavior of wild-type and PDGFRbeta-/- cells within individual chimeric mice. This quantitative chimera analysis method has revealed that during development PDGFRbeta expression is important for all muscle lineages but not for fibroblast or endothelial lineages. Here we report that fibroblasts and endothelial cells, but not leukocytes, are dependent on PDGFRbeta expression during the formation of new connective tissue in and around sponges implanted under the skin. Even the 50% reduction in PDGFRbeta gene dosage in PDGFRbeta+/- cells reduces fibroblast and endothelial cell participation by 85%. These results demonstrate that the PDGFRbeta/PDGF B-chain system plays an important direct role in driving both fibroblast and endothelial cell participation in connective tissue repair, that cell behavior can be regulated by relatively small changes in PDGFRbeta expression, and that the functions served by PDGF in wound healing are different from the roles served during development.  (+info)

Fibrin microbeads (FMB) as biodegradable carriers for culturing cells and for accelerating wound healing. (3/330)

We have developed biodegradable fibrin-derived microbeads as potent cell carriers. The fibrin-derived microbeads, 50-200 microm in diameter, were tested for their attachment to a wide range of cell types. Fibrin-derived microbeads were shown to be greatly haptotactic to cells (such as endothelial cells, smooth muscle cells and fibroblasts), which respond to fibrinogen in contrast to keratinocytes and different cell lines derived from leukocytic lineage. The cells on fibrin-derived microbeads could be maintained for more than 10 d and achieved a high density. 31P-nuclear magnetic resonance was employed to monitor phosphate metabolism in cells, with densities on the order of 100 million cells per g of fibrin-derived microbeads. The 31P-nuclear magnetic resonance adenosine triphosphate and phosphocreatine signals, equivalent to the signal obtained with perfused normal skin, indicated that metabolism of cells on fibrin-derived microbeads was responsive to oxygenation and nutrients. Light, fluorescent, and confocal laser microscopy revealed that the porous fibrin-derived microbeads accommodate up to 200-300 cells due to their high surface area which minimized contact inhibition. Cells could degrade the fibrin-derived microbeads and be transferred to seed culture flasks without trypsinization. In a pig skin wound healing model, fibrin-derived microbeads + fibroblasts were transplanted into full thickness punch wounds. This procedure was compared with other treatment modalities, such as the addition of human platelet-derived growth factor BB or fibrin-derived microbeads alone. By the third day after wounding, only the wounds in which fibroblasts on fibrin-derived microbeads were added showed significant formation of granulation tissue. Based on the above, we project many uses of our novel fibrin-derived microbead technology for cell culturing, wound healing and tissue engineering.  (+info)

Survival, integration, and differentiation of cardiomyocyte grafts: a study in normal and injured rat hearts. (4/330)

BACKGROUND: Cardiomyocyte grafting augments myocyte numbers in the heart. We investigated (1) how developmental stage influences graft survival; (2) whether acutely necrotic or healing cardiac lesions support grafts; and (3) the differentiation and integration of cardiomyocyte grafts in injured hearts. METHODS AND RESULTS: Cardiomyocytes from fetal, neonatal, or adult inbred rats were grafted into normal myocardium, acutely cryoinjured myocardium, or granulation tissue (6 days after injury). Adult cardiomyocytes did not survive under any conditions. In contrast, fetal and neonatal cardiomyocytes formed viable grafts under all conditions. Time-course studies with neonatal cardiomyocytes showed that the grafts recapitulated many aspects of normal development. The adherens junction protein N-cadherin was distributed circumferentially at day 1 but began to organize into intercalated disk-like structures by day 6. The gap junction protein connexin43 followed a similar but delayed pattern relative to N-cadherin. From 2 to 8 weeks, there was progressive hypertrophy and the formation of mature intercalated disks. In some hearts, graft cells formed adherens and gap junctions with host cardiomyocytes, suggesting electromechanical coupling. More commonly, however, grafts were separated from the host myocardium by scar tissue. Gap and adherens junctions formed between neonatal and adult cardiomyocytes in coculture, as evidenced by dye transfer and localization of cadherin and connexin43 at intercellular junctions. CONCLUSIONS: Grafted fetal and neonatal cardiomyocytes form new, mature myocardium with the capacity to couple with injured host myocardium. Optimal repair, however, may require reducing the isolation of the graft by the intervening scar tissue.  (+info)

Expression of cardiac angiotensin-converting enzyme after myocardial infarction. (5/330)

AIM: To localize cardiac angiotensin-converting enzyme (ACE) during left ventricular repair after myocardial infarction (MI). METHODS: Cardiac ACE was examined by immunohistochemical staining using monoclonal and polyclonal antibodies against ACE 24 h, 1 wk, 2 wk, 3 wk, and 6 wk after coronary artery ligation in rats. Immunofluorescent double staining technique was applied to distinguish the cells which express ACE. RESULTS: ACE staining was confined to the endothelial cells and distributed in normal cardiac tissue in a gradient pattern along the vascular tree: present around the whole circle of arterial endothelium, present in about 20% of the capillaries, and absent in the veins. One week after MI, ACE expression was noted in the granulation tissue. Three weeks after MI, necrosis within the infarction was replaced by granulation tissue and fibrous tissue which showed strong over-expression of ACE. Six weeks after MI, the region with positive ACE staining regressed and the area with high collagen content on the endocardial side showed only weak ACE stain. Most of the ACE-positive cells in the ACE-over-expression-area were endothelial cells. A few macrophages seen in these regions were also ACE-positive. CONCLUSION: Cardiac ACE was over expressed during the process of tissue repair following MI, reaching a peak in 3 wk. Endothelial cells took the most part of ACE expression.  (+info)

Expression of cathepsin K messenger RNA in giant cells and their precursors in human osteoarthritic synovial tissues. (6/330)

OBJECTIVE: To investigate the expression of cathepsin K messenger RNA (mRNA) in the giant cells found in human osteoarthritic (OA) synovium and associated reparative connective tissues, and to compare this with mRNA expression of cathepsins B, L, and S, which are cysteine proteases known to be highly expressed by cells of the monocyte/macrophage lineage. METHODS: Sections of human OA synovium were processed for in situ hybridization and probed for cathepsins K, B, L, and S. Serial sections were reacted for tartrate-resistant acid phosphatase (TRAP) and nonspecific esterase (NSE) activity, which are selective markers for the osteoclast and cells of the macrophage/monocyte lineage, respectively. RESULTS: At 3 sites of monocyte infiltration/giant cell formation (granulation tissue, the intimal and subintimal synovial layers, and deep stroma extending to the periphery of osteophytic tissue), both TRAP-positive mono- and multinucleated cells and TRAP-negative, NSE-positive mononuclear precursors were identified. Cells containing both enzyme activities were also found, potentially indicating an intermediate stage of differentiation. The TRAP-positive mononuclear/giant cells, and the occasional NSE-positive precursor, expressed an intense signal for cathepsin K mRNA, but did not express cathepsins B, L, and S. In contrast, the deep zone of phagocytic-like cells adjacent to sites of ossification expressed high levels of mRNA for cathepsins L, B, and S as well as cathepsin K mRNA. CONCLUSION: Giant cells that form within OA synovial tissue express high levels of cathepsin K mRNA. It appears that cathepsin K acts principally to digest the bone (and cartilage) fragments sheered from the joint surface during OA. The high TRAP activity and the undetectable expression of the macrophage-associated degradative proteases (cathepsins B, L, and S) by synovial giant cells strengthens the hypothesis that cathepsin K is the primary protease involved in bone degradation. At sites of synovial osteogenesis, a population of phagocytic-like cells expressed TRAP and cathepsins B, L, S, and K, and may represent blood-derived macrophages pushed toward an osteoclast phenotype.  (+info)

Connective tissue growth factor mediates transforming growth factor beta-induced collagen synthesis: down-regulation by cAMP. (7/330)

Connective tissue growth factor (CTGF) is a cysteine-rich peptide synthesized and secreted by fibroblastic cells after activation with transforming growth factor beta (TGF-beta) that acts as a downstream mediator of TGF-beta-induced fibroblast proliferation. We performed in vitro and in vivo studies to determine whether CTGF is also essential for TGF-beta-induced fibroblast collagen synthesis. In vitro studies with normal rat kidney (NRK) fibroblasts demonstrated CTGF potently induces collagen synthesis and transfection with an antisense CTGF gene blocked TGF-beta stimulated collagen synthesis. Moreover, TGF-beta-induced collagen synthesis in both NRK and human foreskin fibroblasts was effectively blocked with specific anti-CTGF antibodies and by suppressing TGF-beta-induced CTGF gene expression by elevating intracellular cAMP levels with either membrane-permeable 8-Br-cAMP or an adenylyl cyclase activator, cholera toxin (CTX). cAMP also inhibited collagen synthesis induced by CTGF itself, in contrast to its previously reported lack of effect on CTGF-induced DNA synthesis. In animal assays, CTX injected intradermally in transgenic mice suppressed TGF-beta activation of a human CTGF promoter/lacZ reporter transgene. Both 8-Br-cAMP and CTX blocked TGF-beta-induced collagen deposition in a wound chamber model of fibrosis in rats. CTX also reduced dermal granulation tissue fibroblast population increases induced by TGF-beta in neonatal mice, but not increases induced by CTGF or TGF-beta combined with CTGF. Our data indicate that CTGF mediates TGF-beta-induced fibroblast collagen synthesis and that in vivo blockade of CTGF synthesis or action reduces TGF-beta-induced granulation tissue formation by inhibiting both collagen synthesis and fibroblast accumulation.  (+info)

Arnebin-1 accelerates normal and hydrocortisone-induced impaired wound healing. (8/330)

Wound healing involves inflammation, cell proliferation, matrix deposition, and tissue remodeling. Interaction of different cells, extracellular matrix proteins, and their receptors are mediated by cytokines and growth factors during wound healing. In this study, we have evaluated the effect of arnebin-1, a natural product isolated from Arnebia nobilis, on normal and impaired wound healing in cutaneous punch wound model. Arnebin-1 was applied topically daily on wounds of hydrocortisone-treated or untreated animals. Arnebin-1 significantly accelerated healing of wounds with or without hydrocortisone treatment as revealed by a reduction in the wound width and gap length compared with controls. Arnebin-1 treatment promoted the cell proliferation, migration, and vessel formation to form a thick granulation tissue and re-epithelialization of the wounds. An increase in the synthesis of collagen, fibronectin and transforming growth factor-beta1 was seen in arnebin-1-treated wounds compared with the untreated control. As transforming growth factor-beta1 is known to enhance wound healing, and associated with the wound healing defect in hydrocortisone-treated wounds, the enhanced expression of transforming growth factor-beta1 at both translational and transcriptional level by arnebin-1 may be responsible for the enhancement of wound healing during normal and impaired wound repair. These studies suggest that arnebin-1 could be developed as a potent therapeutic agent for wound healing in steroid-impaired wounds.  (+info)

Photo by Christa Moody. We have all heard the term proud flesh in relation to the healing process of the horse. So, what is proud flesh? It is not a mystery, but rather a normal tissue that has gone amuck. When there is a wound the surrounding tissue responds by attempting to heal the wound as quickly as possible. What happens then is there is too much tissue formed. When granulation tissue grows out and protrudes from the wound, then the granulation tissue is known as proud flesh. Proud flesh is not conducive to wound healing as it prevents the wound from epithelializing (the process of the skin cells covering the wound)....The granulation tissue can become so large it appears to be a tumor, usually obliterating the original wound. Granulation tissue in this excessively exuberant form usually occurs within wounds on the distal (lower) leg of the horse, such as wounds over the cannon bone or pastern area. Granulation tissue in this form can be very difficult to manage. Proud Flesh/by: ...
The development of postoperative granulation tissue is one of the main postoperative risks after lumbar spine surgery. This granulation tissue may lead to persistent or new clinical symptoms or complicate a follow up surgery. A sensitive non-invasive imaging technique, that could diagnose this granulation tissue at the bedside, would help to develop appropriate treatments. Thus, the purpose of this study was to establish a fast and economic imaging tool for the diagnosis of granulation tissue after lumbar spine surgery, using a new integrated Optical Imaging (OI)/X-ray imaging system and the FDA-approved fluorescent contrast agent Indocyanine Green (ICG). 12 male Sprague Dawley rats underwent intervertebral disk surgery. Imaging of the operated lumbar spine was done with the integrated OI/X-ray system at 7 and 14 days after surgery. 6 rats served as non-operated controls. OI/X-ray scans of all rats were acquired before and after intravenous injection of the FDA-approved fluorescent dye Indocyanine Green

TY - JOUR. T1 - Wound splinting modulates granulation tissue proliferation. AU - Carlson, Mark Alan. AU - Thompson, Jon S. PY - 2004/7/1. Y1 - 2004/7/1. N2 - Attachment of the extracellular matrix to a substratum is important for fibroblast survival and proliferation in three-dimensional in vitro culture systems. We hypothesized that wound matrix attachment in a wound splinting model would modulate wound cell proliferation in vivo. Male rats were excisionally wounded on the dorsum, and a splint was sutured to the wound edge. In one experiment (N=12), 6 rats were desplinted on day 5, and then all were sacrificed 24 h later, 6 h after 5-bromo-2′-deoxyuridine (BrdU) injection. In the second experiment (N=18), 6 rats each were desplinted, desplinted with wound edge release, or not disturbed, followed by BrdU injection and sacrifice 24 h later. BrdU-labeled nuclei were quantified on frozen sections of granulation tissue, cut at three different levels. In the first experiment, the percentage of ...

That bump under her button is granulation tissue. Its so frustrating! It wasnt even there before her nap! It came on so fast! We have been so careful to keep it clean and dry, and now have begun the battle every other gtube parent has fought.. Granulation tissue in and of itself is a normal thing. Its just gross and in the way and unpleasant. It leaks a lot of mucus, and can grow really bad really fast. We have to be careful to not let it get infected, so it really has to stay under control.. All it is, though, is her bodys hard work of trying to heal. Its the tissue trying to close the hole they just put in her, the hole we call a stoma, except it cant close because the gtube is in the way. So the new tissue gets pushed up and out, creating the extra ring bubble over where the hole in her belly is, as if it were try to close by growing up and around the tube itself.. Now we have a special ointment we have to keep on it to burn it off, and they will continue to use silver nitrate every ...
What drug can cause Excessive Granulation Tissue as their side effect? Check drug and medication side effect reports associated with Excessive Granulation Tissue
In the spine, the specimens studied have either been surgically resected in advanced disease or taken from autopsies. There is inflammatory granulation tissue in the paravertebral connective tissue at the junction of annulus fibrosus and vertebral bone, and in some cases along the entire outer annulus. The outer annular fibers are eroded and eventually replaced by bone, forming the beginning of a syndesmophyte, which then grows by continued endochondral ossification, ultimately bridging the adjacent vertebral bodies. Ascending progression of this process leads to the bamboo spine. Other lesions in the spine include diffuse osteoporosis (loss of trabecular bone despite accretion of periosteal bone), erosion of vertebral bodies at the disk margin, squaring or barreling of vertebrae, and inflammation and destruction of the disk-bone border. Inflammatory arthritis of ...
It is believed that gossypiboma/textiloma is under-reported owing to its medicolegal implications [1], in addition to its asymptomatic nature [2]. The exact incidence is largely unknown, and different estimates have been reported. Depending on the bodys reaction, as well as the characteristics of the retained foreign body, the patient may present acutely, within months of the original surgery, or may have a delayed presentation year thereafter.. We present a rare case where Surgicel (FDA approved agent) was left intentionally for haemostasis, though required surgical removal due to post-operative pain and symptoms related to a foreign body reaction, thereby behaving as a gossypiboma. Surgicel may be removed or left in situ depending on the clinical need. If left in situ, degradation is expected to commence within 24-48 hours and will be surrounded by inflammatory granulation tissue in a weeks time.. Complete degradation will usually occur between 4 and 8 weeks. We believe this case was a Type ...
This study addressed the functional relevance of ILK for skin fibroblast functions in vivo and in vitro. Our results suggest that ILK is necessary to provide a structural link for matrix adhesion sites capable of bearing tensile force, to limit RhoA activity and to promote release of TGFβ1, and that it is an essential component of matrix adhesions for the differentiation of fibroblasts to myofibroblasts, their migration into wound sites and re-establishing a normal dermis.. In vivo analysis of ILK function in fibroblasts was achieved by breeding Ilkfl/fl mice with a strain that carries a tamoxifen-inducible Cre recombinase under the control of a minimal α2(I) procollagen promoter linked to a fibroblast-specific enhancer (Denton et al., 2009; Liu et al., 2009; Sonnylal et al., 2007; Zheng et al., 2002). Efficient deletion of ILK was seen in fibroblasts of Col1-ILK mice, but not in keratinocytes or endothelial cells.. To investigate the contribution of ILK to activation of fibroblasts during ...
The second and third bodies of research have involved the development of electrospun polycaprolactone (PCL) scaffolds in the micron scale range (2-14 µm) to allow good fibroblast infiltration. In vitro biocompatibility and infiltration behaviour of 3T3 GFP dermal fibroblasts, as an exemplar cell type on electrospun PCL scaffolds, were investigated. Additionally, synthesis of polycapolactone-poly(ethylene glycol)-block copolymer (PCL-b-PEG) was included in this study, where it was hypothesized that PCL-b-PEG containing scaffolds may enhance degradation, wettability, and cell-compatibility as previous research has reported. Caprolactone-poly(ethylene glycol) block copolymer were blended with commercial caprolactone (PCL-b-PEG/PCL) and electrospun scaffolds were developed and fully characterised. Selected scaffolds (PCL and PCL-b-PEG/PCL with an average fibre diameter of 4 μm) were compared in terms of: i) in vitro biocompatibility and cell infiltration, ii) mechanical properties, iii) ...

Wet granulation of microcrystalline cellulose (MCC) has the objective of minimizing particle losses caused by elutriation in compression and coating processes. The MCC physical properties suggest the conventional fluidized bed as adequate for the granulation process; however, literature reports the occurrence of poor fluidization dynamic (preferential channels and dead zones) during this particle fluidization. This work reports the granulation of MCC in vibrofluidized bed, using aqueous solution of maltodextrin (35%) as binder. A fractional experimental design (2(5-1)) was developed to assess the influence of process variables: amplitude and frequency of vibration, atomization pressure, inlet air temperature, and granulating solution flow rate on the responses: particle growth, angle of repose, lump index and mass of elutriated particles. The results showed an increase of the Sauter mean diameter related to the original value from 3.17 to 33.11%, confirming the granulation of the material. The ...

A micrograft technique, which minces tissue into micro-fragments |50 μm, has been recently developed. However, its pathophysiological mechanisms in wound healing are unclear yet. We thus performed a wound healing study using normal mice. A humanized mouse model of a skin wound with a splint was used. After total skin excision, tissue micro-fragments obtained by the Rigenera protocol were infused onto the wounds. In the cell tracing study, GFP-expressing green mice and SCID mice were used. Collagen stains including Picrosirius red (PSR) and immunohistological stains for α-smooth muscle actin (αSMA), CD31, transforming growth factor-β1 (TGF-β1) and neutrophils were evaluated for granulation tissue development. GFP-positive cells remained in granulation tissue seven days after infusion, but vanished after 13 days. Following the infusion of the tissue micrograft solution onto the wound, TGF-β1 expression was transiently upregulated in granulation tissue in the early phase. Subsequently, αSMA
Normal wound healing includes a number of overlapping phases. After injury, there is an early inflammatory step characterised by haemorrhage and clotting. At this time, the wound has a provisional serum-derived extracellular matrix, which serves to seal the wound temporarily and allows the invasion of cells that carry out the repair process. In the next phase, consisting of granulation tissue development, fibroblasts invade the wound and commence replacing the provisional matrix with a more mature wound matrix. The fibroblasts present during the early granulation tissue phase resemble immature fibroblasts with a highly synthetic appearance. However, as the granulation tissue phase proceeds, fibroblasts start showing a new phenotype with prominent contractile structures represented by microfilament bundles or stress fibres; these structures express contractile proteins typical of smooth muscle cells, particularly of vascular smooth muscle cells, such as α-smooth muscle actin [1]. Recently, it has been
Horses commonly develop lower leg wounds and some of these wounds are difficult to heal as proud flesh is a major inhibitor of healing in equine wounds. Proud flesh is actually correctly called exuberant or excessive granulation tissue. Granulation tissue is needed to fill in the defect of the wound if it is not sutured. However, in horses, the granulation tissue does not stop growing once the wound defect is filled but keeps growing out of the wound and prevents healing. The question today is about understanding when to bandage lower leg wounds in horses or leave them open to air out. And the answer is it depends on a lot of factors, one of which is your geographic location. Although not reported in the literature, it seems we have a lot more problems with proud flesh in Texas and other warm climates than in colder climates. I dont know if this is due to temperature, flying insect irritation or humidity but many wounds are left open in colder climates while most of ours in Texas require a ...
The best treatment of proud flesh is prevention, and the best prevention i performing a primary closure (suturing) of the wound immediately, or as soon as possible, after the wound occurs. Proud flesh can become a problem when primary closure is not an option, and the skin has to heal through second intention healing. Second intention healing is when the skin has to heal first by granulation tissue forming over the wound, then the skin grows over the granulation tissue. It is at this point you get proud flesh. Another preventative method is to limit the motion in the area of the wound as much as possible. This is generally done by bandaging, or placing the lower limb in a cast. By reducing the motion in the area, you speed the healing process allowing skin to grow over the granulation tissue, which greatly reduces the occurrence of proud flesh ...

Silk-elastin is a recombinant protein polymer with repeating units of silk and elastin blocks. This novel wound healing promoting material has the ability to self-assemble from a liquid to a gel. We have already reported that an aqueous solution of silk-elastin has the potential to accelerate wound healing; however, there are several problems in applying silk-elastin in the clinical setting. To solve these problems, we developed a silk-elastin sponge that is easy to use in the clinical setting. In the present study, we examined whether the wound healing effect of the silk-elastin sponge is equal to the aqueous solution of silk-elastin in vivo. The granulation tissue formation promoting effect of the silk-elastin sponge was equal to that of the aqueous solution the silk-elastin, as after application to the wound surface, the sponge was absorbed and dissolved by the exudate. At body temperature the silk-elastin then formed temperature gel. The silk-elastin gel that was obtained contained abundant

Fibrosis accompanying wound healing can drive the failure of many different organs. Activated fibroblasts are the principal determinants of post-injury pathological fibrosis along with physiological repair, making them a difficult therapeutic target. Although activated fibroblasts are phenotypically heterogeneous, they are not recognized as distinct functional entities. Using mice that express GFP under the FSP1 or alpha SMA promoter, we characterized two non-overlapping fibroblast subtypes from mouse hearts after myocardial infarction. Here, we report the identification of FSP1-GFP(+) cells as a non-pericyte, non-hematopoietic fibroblast subpopulation with a predominant pro-angiogenic role, characterized by in vitro phenotypic/cellular/ultrastructural studies and in vivo granulation tissue formation assays combined with transcriptomics and proteomics. This work identifies a fibroblast subtype that is functionally distinct from the pro-fibrotic alpha SMA-expressing myofibroblast subtype. Our ...
Background. During inflammation, the serum concentrations of granulocyte colony-stimulating factor (G-CSF), plasma interleukin-6 (IL-6), and C-reactive protein (CRP) increase. A positive correlation between CRP and the percentages of neutrophils exhibiting toxic granulation during inflammation has been demonstrated, and that the fluctuations of CRP and toxic granulation of neutrophils were similar. Objectives. We studied whether grading of toxic granulated neutrophils can be used as a surrogate marker for infection or inflammation, and also be an easier method than previously described methods. Materials and methods. We graded 357 consecutive peripheral blood slides from patients on whom a full blood count with differential count and CRP level was performed, according to intensity of toxic granulation in the neutrophil population, according to a newly proposed grading system. Results. The CRP range was between 1 and 530.3 mg/l. The results confirm the association between a rise in CRP and progressive
Abstract: Background: Vacuum-assisted dressing is a noninvasive closure system of the wound, which makes localized and controlled negative pressure. Its mechanical tension reduces edema, stimulates granulation tissue formation and angiogenesis, and prepares the wound bed for closure. In this study, a patient has been presented, who suffered from serious lower extremity wounds due to arterial emboli, one of her wounds has been treated with vacuum-assisted dressing and the other with conventional dressing to evaluate the efficacy of vacuum-assisted dressing in acute ischemic wounds. Methods: A 65-year-old female patient was admitted to the emergency clinic, due to complaint of severe pain in her right lower extremity which suggested an acute arterial occlusion. She immediately underwent an embolectomy operation; however, a few days later, severe ischemia on the leg and foot became appearant. All of the necrosis was sharply debrided under sterile conditions in the operating room, and then lower leg ...

The process of scar formation begins almost immediately following injury; immature scar tissue is susceptible to reinjury and the formation of granulation tissue at the…
How it works Vacuum Therapy:. The basis of this technique is the use of special sponge dressings and vacuum generator that allows you to create a negative pressure in the wound, the consequence of which is the removal of excess exudate, reducing the bacterial contamination of the wound and stimulate the growth of granulation tissue and epithelium.. Vacuum therapy offers a safe and reliable alternative to traditional methods of treatment of large infected soft tissue injuries in infants. Patients positively accept this treatment, because it is more convenient for dressing changes and rapid wound healing, reducing the patients stay in hospital. Special conditions allow healing to eliminate bacterial pathogens and local inflammatory mediators, stimulate the processes of cell proliferation and the formation of granulation tissue, promote the approximation of the wound edges and secondary closure.. Manufacturers of Foryou STAN NPWT device argue that the vacuum wound therapy can be used in patients ...

As for the granulation tissue, its so hard. Im sure that with EB its a constant battle for sure. We struggled with it for a long time. At one point we were seeing an ostomy nurse who was burning it DAILY with silver nitrate! It was not a good thing - and didnt fix the problem. Knowing that Jonah cant have his stoma open to air and gauze free, the granulation tissue is going to be happy. It loves warmth and lack of air flow. One thing Ive found that helps a lot (and I still use it everyday) is Calmoseptine cream. You can get it at Walgreens at the pharmacy counter. Its a wonderful barrier cream meant for tube site leakage. Its amazing. I would recommend putting a layer of it around his button and underneath it right on the stoma when you dressing change. http://www.walgreens.com/store/catalog/Cleansing-and-Disposal/Ointment/ID=prod3285901&navCount=149&navAction=push-product?ext=gooHome_Medical_Top_Performing_New_calmoseptine An $8 tube will last months.

Formation of vessels in a blood clot. Light micrograph showing new vessels (small oval white spaces) in an old established blood clot (thrombus, light pink, centre) that is blocking an artery (dark pink ring). Over time, granulation tissue gradually builds up in a thrombus. This eventually results in replacement of the thrombus by fibrovascular granulation tissue, as seen here. In some cases, larger vessels develop within this tissue. These vessels may allow blood to flow through the previously blocked area and may with time acquire smooth muscle walls. This is known as recanalisation. - Stock Image C003/0233
