Recent studies have pointed out the importance of the molecules in the paracrine mechanisms related to neuronal maintenance and plasticity of lesioned motor and sensory peripheral neurons. Moreover, cultured Schwann cells have been employed experimentally in the treatment of central nervous system lesions, in special the spinal cord injury, a procedure that triggers an enhanced sensorymotor function. Those cells have been proposed to repair long gap nerve injury. METHODS: Here we used double labeling immunohistochemistry and Western blot to better characterize in vitro and in vivo the presence of the proteins in the Schwann cells and in the satellite cells of the DRG as well as their regulation in those cells after a crush of the rat sciatic nerve. RESULTS: FGF-2 and S100\u00df are present in the Schwann cells of the sciatic nerve and in the satellite cells of the DRG. S100\u00df positive satellite cells showed increased size of the axotomized DRG and possessed elevated amount of FGF-2 immunoreactivity. Reactive satellite cells with increased FGF-2 labeling formed a ring-like structure surrounding DRG neuronal cell bodies.Reactive S100\u00df positive Schwann cells of proximal stump of axotomized sciatic nerve also expressed higher amounts of FGF-2. CONCLUSION: Reactive peripheral glial cells synthesizing FGF-2 and S100\u00df may be important in wound repair and restorative events in the lesioned peripheral nerves.<\/jats:p>","DOI":"10.1590\/s0102-86502008000600014","type":"journal-article","created":{"date-parts":[[2008,11,18]],"date-time":"2008-11-18T11:25:55Z","timestamp":1227007555000},"page":"555-560","source":"Crossref","is-referenced-by-count":15,"title":["S100\u00df and fibroblast growth factor-2 are present in cultured Schwann cells and may exert paracrine actions on the peripheral nerve injury"],"prefix":"10.1590","volume":"23","author":[{"given":"Tatiana","family":"Duobles","sequence":"first","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thais de Sousa","family":"Lima","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatriz de Freitas Azevedo","family":"Levy","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerson","family":"Chadi","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"issue":"5","key":"ref1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1046\/j.1460-9568.1999.00589.x","volume":"11","author":"Zhou X.
