The Abelson tyrosine kinase (c-Abl) expression on the mouse uterus and placenta during gestational period

c-Abl is a protein tyrosine kinase which has very important roles in signal transduction, control of the cell cycle, cell motility, proliferation, and inhibition of apoptosis. We hypothesized that c-Abl may play an important role on uterine remodeling during pre-receptive, receptive and non-receptive endometrium. Our aim is to investigate the expression of c-Abl protein tyrosine kinase in uterine remodeling and placental development in mouse gestational stage. We performed c-Abl immunohistochemistry on mouse uterine tissue sections on days 1-9, 11, 13, and 15 of pregnancy. c-Abl was highly upregulated in the uterine luminal epithelium and other endometrial structures including glands and blood vessels in pre-receptive and receptive endometrium. Therefore these results demonstrate a role for c-Abl in uterine remodeling during decidualization, implantation, and placentation throughout gestation.
