1. Fibroblast morphology, growth rate and gene expression in facial melasma
Abstract Background: In addition to melanocytic hyperfunction, changes are observed in the upper dermis of melasma, and fibroblasts play a central role in collagen synthesis and pigmentation induction. Objective: To explore the morphology, growth rate, and gene expression profile of fibroblasts from the skin with melasma in comparison to fibroblasts from t

2. In vitro cytotoxicity of chemical preservatives on human fibroblast cells
ABSTRACT Preservatives are widely used substances that are commonly added to various cosmetic and pharmaceutical products to prevent or inhibit microbial growth. In this study, we compared the in vitro cytotoxicity of different types of currently used preservatives, including methylparaben, imidazolidinyl urea (IMU), and sodium benzoate, using the human newb

3. Comparison of primary human gingival fibroblasts from an older and a young donor on the evaluation of cytotoxicity of denture adhesives
Abstract Denture adhesives (DA) improve the retention and stability of ill-fitting dentures, especially for older adults. These materials should be biocompatible, i.e., they cannot cause undesired biological responses and be non-cytotoxic to oral tissues. However, in vitro testing of DA biocompatibility employing primary cell culture may possibly be affected

4. Expression of lymphatic markers and lymphatic growth factors in psoriasis before and after anti-TNF treatment
BACKGROUND: Angiogenesis is an early stage of psoriatic lesion development, but less is known about lymphagiogenesis and its role in the development of psoriasis. OBJECTIVE: To examine the expression of specific lymphatic markers and lymphatic growth factors in untreated psoriatic skin, in the unaffected skin of patients and skin of healthy volunteers, as w

5. Application of platelet-rich plasma in the treatment of chronic skin ulcer - Case report
The platelet-rich plasma (PRP) has proved promising regarding its applicability in dermatology, especially in the healing of chronic ulcers. The autologous platelet-rich plasma is obtained by centrifuging the blood, so that the components are separated by density gradient. The final product is a gel rich in growth factors that act in tissue repair by activat

6. Análise da ação do ACTH e do peptídeo N-terminal da POMC na proliferação, morte celular e na expressão das proteínas de genes de resposta secundária na supra-renal de ratos hipofisectomisados ou tratados com dexametasona. / Analysis of ACTH and the peptide N-terminal POMC in proliferation, cell death, and expression of secondary response genes in adrenal glands of hypophysectomized or dexamethasone treated rats.
Different experimental models have been used to study the trophic action of ACTH in adrenal, which seems to be important in proliferation and cell death in vivo. This hypothesis was tested using hypophysectomized or dexamethasone treated rats, and through IHC we evaluate: 1-the BrdU incorporation in different adrenal cortex zone after i.p. of ACTH, FGF2 or N

7. Plasma rico em plaquetas no tratamento de tendinite em eqüinos: avaliação clínica, ultrasonográfica e histopatológica / Clinical, ultrasonographic and histopathological evaluation of tendinitis in horses treated with platelets-rich plasma
Platelet-rich plasma (PRP) is an autologous and economic source of intensal growth factors, with great therapeutic potential. This work aimed to carry out clinical, ultrasonographic and histopathological evaluations of the effect of PRP on the treatment of induced tendonitis of the superficial digital flexor tendon (SDFT) of horses. Thus, six healthy gelding

8. Low-intensity laser therapy (LILT) effects on fibroblast growth factors expression by human gingival fibroblasts / Efeito da terapia com laser em baixa intensidade (LILT) na expressão de fatores de crescimento da família FGF por fibroblastos gengivais humanos
Low-intensity laser therapy (LILT) has been the subject of researches to understand the mechanisms by which the laser acts stimulating wound healing. This process is dependent of a signaling transfer between epithelium and connective tissue and it influences cellular proliferation and migration. Growth factors are directly involved in these mechanisms. The a

9. Analise dos efeitos e dos mecanismos de ação do fator de crescimento transformante- beta 1, interferon gama e iclosporina A na transdiferenciação dos fibroblastos gengivais em miofibroblastos / Effects of transforming growth factor- beta 1, interferon gamma and cyclosporin A on transdifferentiation of gingival fibroblasts in myofibroblasts
Myofibroblasts are the main cellular type involved in extracellular matrix deposition in fibrotic diseases. Relatively little is known about the underlying mechanisms that regulate myofibroblast emergence (transdifferentiation), however the regulatory cytokine transforming growth factor-beta 1 (TGF- beta 1) has been traditionally considered an inducer of the

10. Myofibroblasts are frequent in the stroma and invasive front of oral squamous cell carcinomas where they control the tumoral behavior by stimulating cellular proliferation and matrix metalloproteinase 2 activity of the tumor cells / Miofibroblastos são frequentes no estroma e no fronte invasivo dos carcinomas espinocelulares orais onde controlam o comportamento tumoral por estimular a proliferação celular e a atividade da metaloproteinase de matriz 2 das celulas tumorais
Myofibroblasts are characterized by the expression of elevated amounts of growth factors, proteases and extracellular matrix, which may influence the tumor progression. Recent studies have detected myofibroblasts in the stroma of several tumors, including those of breast, kidney, liver, bladder, colon and prostate, being the presence of those cells associate

11. Alternagin-C, a disintegrin-like protein from the venom of Bothrops alternatus, modulates alpha2ß1 integrin-mediated cell adhesion, migration and proliferation
The alpha2ß1 integrin is a major collagen receptor that plays an essential role in the adhesion of normal and tumor cells to the extracellular matrix. Alternagin-C (ALT-C), a disintegrin-like protein purified from the venom of the Brazilian snake Bothrops alternatus, competitively interacts with the alpha2ß1 integrin, thereby inhibiting collagen binding. W

12. Clonagem do Receptor de ACTH de células adrenocorticais Y-1 de camundongo e expressão em fibroblastos 3T3 e células de AR-1 para elucidação de vias de transdução de sinal / Cloning of ACTH receptor from mouse Y1 adrenocortical cells and expression in to mouse 3T3 fibroblasts and AR-1 cells for the study of signal transduction pathways.
The adrenocorticotropic hormone, ACTH, regulates both function and proliferation of adrenocortical cells binding to a specific receptor, ACTHR, which belongs to superfamily of GPCR (G-protein coupled receptors). ACTHR was cloned a few years ago, but the molecular mechanisms underlying the mitogenic and anti-mitogenic actions of ACTH remain unknown, whose elu
