Radioautographic Observations on Transfer of Thymidine-3H in the Trophoblastic Giant Cells in the Early Pregnancy of Rats

Abstract

SummaryThe authors tried to relate the dose of injected 3H-thymidine with the incorporation by secondary trophoblastic giant cells from the 8th to the 11th day of the rat’s pregnancy. It appeared that the labelling of these cells during this period depends on the amount of the labelled compound administered.
