Abstract

In the present study, anti-viral transgenic chickens were developed by transfecting spermatogonial stem cells (TTSSCs) with the fusion gene ECFP-MMx. After injection of the fusion gene ECFP-MMx into testis, frozen testis sections underwent PCR and dot blot testing at 30, 40, 50, 60, 70 and 80 days. ...
