title: 3H-thymidine incorporation into human placental cells in culture.
abstract: Cell cultures of early human placenta were incubated with tritiated thymidine and, with the exception of macrophage-like cells, all cell types were found to synthesize new DNA. The possibility that at least some of the multinucleated cells seen in these cultures have originated from the fusion of mononucleated cells in vitro is discussed.
