A study of the mechanism regulating the growth of organs during embryogenesis

III. The effect of transplants from the myocardial tissue of adult chickens and chick embryos on the myocardium of embryo-recipients
  • I. I. Titova
Experimental Biology


Myocardial tissues of adult hens and chick embryos incubated for 14 and 17 days were transplanted to membranes of chick embryos incubated for 4, 6, 8 and 10 days. Myocardial tissues of adult hens stimulated the growth of the recipient organs, although to a lesser degree than the tissues of the spleen. This depended on the less intensive (in comparison with the spleen) growth of the myocardial tissues on the extra-embryonic membranes of the embryos, and, consequently, on the fact that the total mass of tissues affecting the embryo organism was smaller in the case of myocardial transplantation. An increase of the transplanted myocardial tissue mass leads to a much more intensive growth stimulation of heart growth in the embryo-recipients.
