Retinoic acid as a regulator of planarian morphogenesis

Retinoic acid as a regulator of planarian morphogenesis The effect of retinoic acid on regeneration of two species of asexual planarian races, Girardia tigrina and Schmidtea mediterranea, was studied. It was established that retinoic acids at physiological concentrations (10−7–10−10 M) inhibit the regeneration of the head part of planarians but have no effect on tail blastema growth. It is shown that regeneration of the head part is inhibited as a result of arrest of the cell cycle of neoblasts, proliferating stem cells, during the transition from the G 1/G 0 to the S phase. Thus, the morphogenetic role of retinoic acids in planarians, primitive bilaterally symmetrical animals, has been demonstrated. Russian Journal of Developmental Biology Springer Journals
