Cultivation and transfer of porcine type A spermatogonia

Cultivation and transfer of porcine type A spermatogonia A cell population enriched with type A spermatogonia has been isolated from the boar testes. Cell types occurring during isolation were morphologically characterized, factors maintaining the cultured spermatogonia in the undifferentiated state were studied, and these cells were transferred to sterile recipients preliminarily treated with busulfan. The cells of spermatogenic epithelium cultivated in vitro for 24 h were used for transfer experiments. The transfer efficiency was estimated within 27 and 29 days according to the histological picture of the testes and the isolated cultures. Spermatogenic cells at various developmental stages and a few Sertoli cells and spermatozoa were found on sections and in cell suspensions.

Abstract

A cell population enriched with type A spermatogonia has been isolated from the boar testes. Cell types occurring during isolation were morphologically characterized, factors maintaining the cultured spermatogonia in the undifferentiated state were studied, and these cells were transferred to sterile recipients preliminarily treated with busulfan. The cells of spermatogenic epithelium cultivated in vitro for 24 h were used for transfer experiments. The transfer efficiency was estimated within 27 and 29 days according to the histological picture of the testes and the isolated cultures. Spermatogenic cells at various developmental stages and a few Sertoli cells and spermatozoa were found on sections and in cell suspensions. Sperm samples could be taken from recipient boars within nine months after the transfer. Microsatellite analysis of DNA showed the endogenous pattern of spermatogenesis. Thus, it was shown that spermatogenic donor cells can restore and maintain spermatogenesis of a recipient for at least 30 days. However, the donor cells were fully forced by the recipient reserve cells, type A0 spermatogonia, within eight to nine months.
