Sigma reduced serum ii collagen invasion
WebFirst, few in vitro or in vivo studies have directly examined the role of specific MMPs in type I collagen invasion (Benbow et al. 1999). In vitro, MMP-9 and MMP-3 are the only metalloproteinases that have been indirectly linked to cell invasion programs through type I collagen gels (Lochter et al. 1997a; Mason et al. 1999). WebEpithelial-to-mesenchymal transition is a process of cellular transdifferentiation during which epithelial cells lose their cell–cell contacts and acquire changes in cell shape and motility, and a capacity for invasion. 18 It is characterized by the reduced expression of an epithelial-derived marker protein (E-cadherin), and the increased expression of …
