چکیده

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.

Study of Basement Membrane Type IV Collagen Appearance in the Brain Choroids Plexus of Mouse Fetuses

Introduction & Objective: The brain choroids plexus (BCP) plays an important role in the cerebrospinal fluid (CSF) production, but its characterization is still incomplete. Collagen type IV, is one of the most important proteins of basement membrane (BM) and extracellular matrix (ECM) of BCP. In the present study we investigated the differential period of type IV collagen in basement membrane...

The Role of Type IV Collagen in Developing Lens in Mouse Fetuses

Objective(s) Extracellular matrix (ECM) and basement membrane (BM) play important roles in many developmental processes during development and after birth. Among the components of the BM, collagen fibers specially type IV are the most important parts. The aim of this study was to determine the time when collagen type IV appears in the BM of lens structure during mouse embryonic development. M...

Multiple mechanisms of dissociated epidermal cell spreading

To test the possibility that epidermal cells use a common basement membrane protein whenever they spread, in vitro experiments were conducted using trypsin-dissociated guinea pig epidermal cells and the following proteins: human serum, bovine serum albumin, serum fibronectin, Type IV collagen, laminin, and epibolin (a recently described serum glycoprotein which supports epidermal cell spreading...

Structure and function of basement membrane.

Progress has been made in identifying and characterizing basement membrane macromolecules, including type IV collagen, laminin, a heparan sulfate proteoglycan and bullous pemphigoid antigen. Basement membrane contains a unique collagen, type IV collagen, which is formed of pro alpha 1(IV) (Mr = 185,000) and pro alpha 2(IV) (Mr = 170,000) chains. As opposed to the fibrillar pattern seen with oth...
