title: Primary culture of normal rat adrenocortical cells. I. Culture conditions for optimal growth and function.
abstract: Rat adrenocortical cells retained their differentiated characteristics over 2 wk in culture without a specific requirement for additives other than inorganic salts, amino acids, vitamins, and fetal bovine serum. The cells were maintained free from fibroblast overgrowth by substitution of D-value in place of L-valine in the medium. Corticotropin (ACTH) inhibited the growth of adrenocortical cells in this medium and the effect was reversible. The adrenocortical cells had a limited capacity for growth as reflected by total cell counts and [3H]thymidine uptake with cells from young animals demonstrated a greater potential for DNA synthesis than cells obtained from mature animals. A very sensitive assay for ACTH using a small number of cells in primary culture also is described.
