Short Communications


Cell suspensions were prepared from adult rat pituitary intermediate lobes and grown in medium TC 199 supplemented with foetal calf serum. 7 or 8 days old cultures were pulse labelled with tritiated thymidine and thereafter processed for immunostaining using an antiserum against a synthetic α-1-28-ACTH-analogue.

Immunreactivity was mainly confined to epithelial cells, but some spindle-shaped cells were also immunpositive. Thymidine incorporation was observed in some immunopositive cells which shows that cells committed to hormone production may enter the mitotic cycle.
