Induction of pituitary lactotrope differentiation by luteinizing hormone alpha subunit

Résumé

Addition of gonadotropin releasing hormone to cultures of fetal rat pituitary induced differentiation of lactotropes as revealed by immunocytochemistry. Antiserum to luteinizing hormone (LH) (recognizing native LH), but not antiserum to LH-β (recognizing both native LH and its β subunit), inhibited this induction. Further addition of highly purified LH-α subunit in culture medium also induced lactotrope differentiation. Thus, the α subunit may have a specific biological activity of its own with probable practical use in clinical investigations.
