Biosynthesis and secretion of salusin-alpha from human cells.

abstract：:Pituitary cells from 14-day-old rats were separated by unit gravity velocity sedimentation, and a highly enriched population of gonadotrophs was established in reaggregate cell culture in serum-free and serum albumin-free defined culture media. The medium conditioned by these aggregates was concentrated, ultrafiltrate...
