Immunohistochemical detection of human placental cytochrome P-450-associated mono-oxygenase system inducible by maternal cigarette smoking.

abstract：:The implantation of the blastocyst and early development of the placenta are crucial for the success of implantation and pregnancy. However, the formative stages of human placental development are largely unknown because of their existence in a 'black box' where access to samples is extremely limited for ethical reaso...
