[Effect of syngenic lymphocytes on allogenic inhibition of hematopoietic stem cells of embryonic liver].
The transplantation of liver from the embryos and newborn C57BL-6 mice to the lethally irradiated hybrids (CBA X C57BL/6) F1resulted in 90% allogenic inhibition of the colony-forming activity of the donor elements. The degree of allogenic inhibition of liver cells of 19 days old embryos and newborn mice may be changed with the help of syngenic lymphocytes of adult mice or delayed transplantation of cells 72 hrs following the irradiation of recipients but these procedures proved to be ineffective with the liver cells of 13 and 16 days old embryos. A suggestion is put forward to the effect that the allogenic inhibition is based on the active reaction of recipient hybrids (CBAXXC57BL/6) F1 to the stem hemopoietic cells of C57BL/6 mice.
