Method of preparing basement membrane, method of constructing basement membrane specimen, reconstituted artificial tissue using the basement membrane specimen and process for producing the same

摘要

The object of the present invention is to provide a method for preparing a basement membrane comprising extracellular matrices having a function to control morphology, differentiation, proliferation, motility, function expression and the like of cells. This basement membrane is formed by culturing cells having an ability to form a basement membrane on a fibrous collagen matrix coated with a polymer having a sugar chain. This sugar chain coat can localize a receptor which has an activity to accumulate a basement membrane component on the basal surface of the cells.
