Use of biodegradable polymers for tissue engineering applications

摘要

BIOMEDICAL engineering is generally defined as an extension of chemical engineering towards biomaterials.Tissue engineering is one of its main branches.Its concept was born when several investigators realized that when cells are placed close enough to each other they form structures identical with those formed by such cells in vivo.This apparently may be achieved,thanks to signals that living cells are able to exchange with the neighboring ones.
