Epidermal cells from adult guinea pig skin attach and differentiate preferentially on substrates of type IV (basement membrane) collagen, compared to those of types I--III collagen. In contrast, guinea pig dermal fibroblasts attach equally well to all four collagen substrates. Fibronectin mediates the attachment of fibroblasts but not of epidermal cells to collagen.
与I - III型胶原蛋白相比,成年豚鼠皮肤的表皮细胞优先附着并分化于IV型(基底膜)胶原蛋白底物上。相比之下,豚鼠真皮成纤维细胞对所有四种胶原蛋白底物的附着情况相同。纤连蛋白介导成纤维细胞而非表皮细胞与胶原蛋白的附着。
