摘要
The roles of connective tissue growth factor ( CTGF) and transforming growth factor-beta (TGF-beta), both well-known collagen production stimulators, were examined in skin aging. Aged skin and fibroblasts exhibited a coordinate decrease in CTGF, TGF-beta, and type I procollagen expression and content. CTGF knockdown and TGF-beta blockade in normal dermal fibroblasts reduced procollagen expression, whereas overexpressing CTGF increased procollagen by a TGF-beta/Smad signaling-dependent mechanism without involving Smad2/3.
