[Induction of N-acetyllactosamine synthetase activity in the mouse mammary gland by prolactin and placental lactogen hormone].
The authors show that the ovine prolactine promote induction of N. acetyl lactosamine synthetase in tissue culture of mammary glands of pregnant mice. A crude extract of human placenta has also a lactogenic activity as tested by the same method, but in this case the blank values are very high for large concentration of crude extract. The molecular forms of HCS are tested: the slow band has a lactogenic activity, the intermediate band has no activity and the rapid band seems to be inhibitory.
