title: Secretion of type IV collagen by keratinocytes of human adult.
abstract: Secretion of type IV collagen by keratinocytes was studied by anti-type IV collagen immunoglobulin in pure keratinocyte culture of the human adult. The cultivated keratinocytes secreted type IV collagen into the space between the cell growth and the underlying fixed film of human skin collagen type I. The secreted collagen was accumulated on the cell surface to form junction structures.
