In this study, we show a more efficient method for isolation and cultivation of dermal papilla cells from hair follicles of human scalp skin. The dermal partments of low hair follicles were pulled out from cutaneous fat and the bulb epithelium was teased out from the fibrous sheath with attached dermal papilla by applying gentle pressure with the tip of an(More)
INTRODUCTION Rheumatoid arthritis (RA) is characterized by synovial lining hyperplasia, in which there may be an imbalance between the growth and death of fibroblast-like synoviocytes (FLSs). Antibodies against citrullinated proteins are proposed to induce RA. This study aimed to investigate the pathogenic role of citrullinated fibronectin (cFn) in RA. (More)
Lysyl oxidase (LOX) serves an important role in remodeling the extracellular matrix and angiogenesis in various types of cancer; however, whether LOX is involved in the pathogenesis of rheumatoid arthritis remains unknown. In order to investigate this in the present study, β‑aminopropionitrile, an inhibitor of LOX, was injected intraperitoneally into rats(More)
OBJECTIVE To investigate the relationships between skin photoaging and point mutations in mitochondrial DNA (mtDNA) control region for replication of dermal fibroblast. METHODS Cultured dermal fibroblasts were treated by 8-methoxypsora len /ultraviolet A (8-MOP/UVA). mtDNA was extracted by one-step-method and th e PCR products of D-loop and adjacent(More)
