Expression of tumor necrosis factor-alpha in mouse spermatogenic cells.
1 Jul 1993
Abstract excerpt
Enriched fractions of spermatogenic cells were isolated by unit gravity sedimentation and analyzed both for the presence of secreted tumor necrosis factor-alpha (TNF alpha) in vitro by bioassay and for the presence of TNF alpha mRNA by Northern blot analysis. Small quantities of bioactive TNF alpha were consistently detected in medium conditioned by round spermatid fractions. Both pachytene spermatocyte and round...
