These initiate signal transduction pathways such as the AKT/mTOR[5] and SMAD[6] pathways that ultimately lead to the proliferation and activation of fibroblasts, which deposit extracellular matrix into the surrounding connective tissue. In superior organisms, and also in humans, regeneration may have been selected negatively and replaced by fibrosis in the course of evolution, to warrant species survival: in fact, unchecked pluripotent cell production and proliferation can lead to tumour development and the potential death of a single individual.

However in certain environments, fibrosis can become a self-perpetuating process leading to incomplete muscle regeneration. Repairing of the damaged tissue is a fundamental biological process. 2A, there was no significant difference in cell proliferation between the two groups in vitro, but the cell proliferation ability of the PCL/PVA mesh group was slightly stronger than the control at the 4 daytime and 9 daytime points.
