title: Effect of dibutyryl cAMP and theophylline on cultured rat embryonic shields.
abstract: Effects of N6, O2 dibutyryl adenosine 3',5'-cyclic monophosphate (db-cAMP) and theophylline (Th) on cultured rat embryonic shields were studied. After addition of db-cAMP to the culture medium, an increase of the weight of explants and of the incidence of the skeletal muscle was observed. Theophylline seems to be ineffective.
