Sixty male rats were randomized to nontreated (controls) and LGF-treated, EDS-treated, and EDS + LGF-treated groups. Testes were obtained on days 10 (T1), 21 (T2), and 35 (T3) after EDS treatment, embedded in paraffin, and analyzed by immunohistochemistry and Western blot. LGF improved the recovery of the seminiferous epithelia, the appearance of the mature pattern of Leydig cell interstitial distribution, and the expression of mature SR-BI. Moreover, LGF treatment resulted in partial recovery of HSL expression in Leydig cells and spermatogonia. No changes in serum testosterone were observed in control or LGF-treated rats, but in EDS-castrated animals LGF treatment induced a progressive increase in serum testosterone levels and 3\u03b2-HSD expression. Based on the pivotal role of SR-BI in the uptake of cholesteryl esters from HDL, it is suggested that the observed effects of LGF would facilitate the provision of cholesterol for sperm cell growth and Leydig cell recovery.<\/jats:p>","DOI":"10.1152\/ajpendo.00329.2014","type":"journal-article","created":{"date-parts":[[2014,11,12]],"date-time":"2014-11-12T04:03:26Z","timestamp":1415765006000},"page":"E111-E121","source":"Crossref","is-referenced-by-count":2,"title":["Liver growth factor induces testicular regeneration in EDS-treated rats and increases protein levels of class B scavenger receptors"],"prefix":"10.1152","volume":"308","author":[{"given":"M.
