These results suggest that in the early stages of nerve regeneration endogenous laminin and fibronectin not only regulate the growth of regenerating nerve fibers, but also exert a positive influence on perineurial cells and macrophages both of which play important roles in nerve tissue injury and repair. 这些结果提示在神经再生的早期,内源性Laminin和Fibronectin不但调节再生神经纤维的生长,对在神经损伤和再生中起重要作用的巨噬细胞和成纤维细胞也有积极的影响。
