| Abstract: | This study was performed to culture and preliminarily identify the primordial germ cells (PGCs) isolated from the genital ridge of the Mongolian sheep fetus. The growth characteristics of the sheep PGCs were detected in different culture systems such as culture media, resources, and state and passages of feeder cells. The obtained embryonic germ (EG) cells were identified by morphology, enzymology, and immunofluorescence. The results showed that the sheep EG cell colonies were ridgy, typically nest like, and compact, and had regular edges. Alkaline phosphatase staining reaction was weakly positive. EG cells expressed Kit, Rex-1, Nanog, and Oct-4. Immunofluorescence detection was weakly positive for Oct3/4, whereas positive for SSEA-1, SSEA-3, SSEA-4, TRA-1-61, and TRA-1-80. |
