title: Preferential modulation of embryonic cell proliferation and differentiation by embryonic interferon.
abstract: Embryonic-interferon (E-IFN), a novel species of interferon (IFN) produced solely by embryo cells, inhibited the proliferation of embryo cells in early gestation preferentially vis-à-vis fetal cells in late gestation but had little effect on the in vitro differentiation of embryonic pre-adipocytes to adipocytes. In contrast, mature-interferon (M-INF) did not exhibit this preferential inhibition of cell proliferation and did inhibit pre-adipocyte differentiation. These results suggest that the function of E-INF is different from that of M-IFN and that this function may involve modulation of the developmental process.
