We report In vitro colony formation of spermatogonia stem cells (SSC) from prepubertal lambs in glial cell line-derived neurotrophic factor (GDNF) and cerebrospinal fluid 1 (CSF1). Testes cells were isolated by two-step enzymatic digestion for differential plating incubated in 40ng/ml GDNF), 40ng/ml CSF1 with 40ng/ml GDNF) or 40ng/ml CSF1). Controls were not treated. Colonies were assayed at 4, 7 and 10 days cultivation by immunocytochemistry against PGP9.5 and ultrastructure by light and transmission electron microscopy. Compared with day 4, stem cell colonies had grown 6.8 in controls, 39% in CSF, 29 in GDNF and 48% in both (P < 0.05). Surface area of all colonies increased 48-52% (P<0.05). We find that GDNF with CSF1 may enhance growth of prepubertal sheep stem cells.
