Aspects récents de la morphogenèse chez les Planairesroblèmes que les chercheurs des 20 dernières années se sont efforcés de résoudre ont trait d’une part à la nature et aux propriétés des cellules de régénération, d’autre part aux facteurs intervenant dans la morphogenèse régénératrice.

Species Differentiation and Ecological Relations of Planarians W. C. Curtis, F. Stéphan-Dubois, etc.), effects of pharmacological and carcinogenic agents (many investigations widely scattered in the literature), the morphogenetic interrelations of various organs during their development (E.

Tracer Studies of the Uptake of Organic Compounds by Planarians of contact. In addition, the rate of loss of the label when the planarian was removed from the tracer solution and the distribution of the utilized chemical between “soluble” and “insoluble” compounds were determined. The retention and distribution of the label when transferred by cannibalism were
