Epithelial monolayers from human epididymal and efferent duct tubules; testosterone metabolism and effects of culture conditions on cell height and confluence.
Corpus epididymal and efferent duct epithelial cells on permeable supports formed confluent monolayers that resisted hydrodynamic equilibrium and created electrical resistance. Monolayers were formed sooner and were of better quality when fetal bovine serum (FBS), rather than bovine serum albumin (BSA), was present in glucose-free, rather than glucose-containing, media. Testosterone was converted to androstenedione by both cell types and conversion of both steroids to 5 alpha-reduced metabolites was higher in cells from the corpus epididymidis than from efferent ducts. Addition of heat-treated human spermatocoele fluid (similar to rete testis fluid) to the apical aspects of the cells increased cell heights when they were initially low, but some cytoplasmic damage was observed. New serum-free media (especially those designed for keratinocytes and mammary epithelial cells) could maintain cultured cells at heights found in situ.
