Establishment of recipient model for spermatogonial stem cells transplantation in Kunming mice.

Abstract

The objective of this study was to establish a recipient model for spermatogonial stem cells (SSCs) transplantation in the Kunming mice after different doses busulfan treatment. The results showed that the most optimal dose of busulfan was 20mg/kg and the most appropriate time for transplantation was 5-7 wk after busulfan treatment. Then, the cloned fragments existed in the testis of recipient mice after 20mg/kg busulfan treatment and the offspring with enhanced green fluorescent protein (EGFP) were produced by the transplanting SSCs. Hence, we established the effective recipient model for donor-derived SSCs transplantation in Kunming mice.
