Abstract
Induction of medullary plate cells or of neural tubes occurred after the implantation of the following materials into the blastocoele of the early gastrula (Triton taeniatus and T. alpestris) : cell-free, centrifuged material from neurulae; pieces of uncleaved eggs first centrifuged and then coagulated in boiling water; ether and petrol-ether extracts of neurulae, using pure triglycerides as vehicles for the oily extracts; the unsaponifiable portion of an ether extract of amphibian embryos; fresh liver from adult newts; and ether extracts of adult newt viscera. No induction could be obtained with the triglycerides used as vehicles for the extracts, or from the triglycerides alone or combined with egg-albumen, cholesterol, tri-hydroxyoestrin, calciferol, or coconut oil. Fresh liver from adult newts gave a much greater % of inductions than the ether or petrol-ether extracts. It is concluded that the organizer is probably a chemical substance soluble in ether and petrol-ether.This publication has 12 references indexed in Scilit:
