abstract：:The expression of stem cell factor (SCF) mRNA and protein was examined in the postnatal rat testis. Northern blot analysis of total RNA from 1-4 days postpartum (dpp) testes showed none or barely detectable levels of the approximately 6.5 kb SCF transcript. At 5 dpp, there was a striking elevation in this mRNA, a timi...
