Neurite outgrowth and proliferation of non-neuronal cells on cryostat sections of adult muscle

Abstract

Rat spinal cord cells were cultured on cryostat sections of innervated and denervated muscle. Neurite outgrowth was greater on sections of denervated muscle, which therefore appeared to act on in vivo nerve regeneration. It seems that muscle sections were able to release into the culture medium factors that increase proliferation of fibroblasts. The muscle therefore appeared able to modulate its interaction with its environment by acting on different types of cells. © 1990.
