Cultures of dividing skin fibroblasts from normal and sclerodermatous human skin have permitted estimations of soluble collagen concentration, net collagen accumulation, cell-doubling times, and the comparison of morphologic and ultrastructural characteristics. In vitro, the scleroderma fibroblast produces more soluble collagen, synthesizes collagen more rapidly, and fourfold more of its protei...

Endometrial cancer is the most commonly diagnosed gynecologic malignancy worldwide; yet the tumor microenvironment, especially the fibroblast cells surrounding the cancer cells, is poorly understood. We established four primary cultures of fibroblasts from human endometrial cancer tissues (cancer-associated fibroblasts, CAFs) using antibody-conjugated magnetic bead isolation. These relatively h...

Background: Breast cancer is a malignant proliferation of epithelial cells that lining the ducts or lobules of the breast. Breast cancer is the second common cancer (after lung cancer) in women. Gallic acid, being a polyphenols, has been reported for its antiproliferative activity against many cancer cell lines. Objective of the present study is effect of gallic acid on proliferation and apopto...

the skin is the largest tissue of man with several functions. cosmetics/cosmeceuticals agents always are needed to be evaluated for their detrimental effects on the skin. nowadays, the therapeutic potential of stem cells has and fibroblasts have increased the hope for a successful cell therapy in aesthetic medicine. stem cells are unspecialized cells capable of renewing themselves through cell ...

BACKGROUND There is a large increase in mast cell numbers in fibrotic lung tissue, suggesting that mast cells may play a part in the pathogenesis of pulmonary fibrosis. Glycosaminoglycans, such as heparan sulphate, that are structurally related to heparin (a mast cell product) are part of the extracellular matrix and known to regulate cell growth. Basic fibroblast growth factor is a heparin bin...

Mitogenic activities on confluent f ibroblasts by sera from patients with scleroderma and normal controls were studied. In experiments using eight different fibroblast strains (one human fetal lung fibroblast, one foreskin fibroblast, three adult skin fibroblast, and three scleroderma fibroblast), pooled scleroderma serum showed lower mitogenic activity by H-thymidine incorporation assay than p...

The utilization of natural extracts as an ingredient in cosmetic products becomes a better choice for customers. Rice berry has been defined potential source anti-free radical properties which is able to be formulated products. Therefore, the objectives this study are 1) investigate antioxidant by ABTS and assays, total compounds phenolic flavonoids cell viability fibroblast NIH3T3 (IC80) ethan...

Gap junctional intercellular communication (GJIC) has been implicated in homeostasis, development, differentiation, wound healing or regeneration and adaptive responses of differentiated cells. The dysfunction of homologous or heterologous GJIC has been associated with the tumorigenic phenotype. Restoration of growth control and the suppression of the tumorigenic phenotype have been previously ...
