Effects of triiodothyronine on the development of GFAP-immunoreactivity and CAT-activity in monolayer cultures of embryonal rat forebrain cells.
Dose-dependent actions of triiodothyronine were studied in serum-containing primary cultures of embryonal rat forebrain cells. Triiodothyronine at concentrations exceeding the normal medium concentration by 2 and 5 nM failed to cause significant changes in the development of CAT-activity and GFAP-immunoreactivity. In the presence of additional 10 and 20 nM T3, however, CAT-activity was increased and GFAP-immunoreactivity was decreased in comparison to cultures maintained with 'normal' (10% FCS-containing) media.
