Abstract
Purpose
To investigate the effect of serum supplementing on short-term culture, fate determination and gene expression of goat spermatogonial stem cells (SSCs).
Methods
Crude testicular cells were plated over Datura-Stramonium Agglutinin (DSA) for 1 h, and non-adhering cells were cultured in the presence of different serum concentrations (1, 5, 10, and 15%) for 7 days in a highly enriched medium initially developed in mice. Colonies developed in each group were used for the assessment of morphology, immunocytochemistry, and gene expression.
Results
Brief incubation of testicular cells with DSA resulted in a significant increase in the number of cells that expressed the germ cell marker (VASA). The expression of THY1, a specific marker of undifferentiated spermatogonia, was significantly higher in colonies developed in the presence of 1% rather than 5, 10 and 15% serum.
Conclusion
Goat SSCs could proliferate and maintain in SSC culture media for 1 week at serum concentrations as low as 1%, while higher concentrations had detrimental effects on SSC culture/expansion.
