Autocrine and paracrine role of steroids during spermatogenesis: Studies in Squalus acanthias and Necturus maculosus
Abstract Due to a cystic mode of spermatogenesis and zonal testes, the spiny dogfish shark ( Squalus acanthias ) and salamander ( Necturus maculosus ) are advantageous for studying the relationship between steroidogenesis and germ cell development. Direct analysis of steroidogenic enzymes and steroi...
