The expression and role of «Tmed2»/TMED2 during the development of the murine embryo and placenta

Normal development of the placenta is crucial for embryonic survival and growth. Tmed2 is a gene, which has been found to be necessary for the formation of the labyrinth layer of the placenta, as well as for embryonic development. The objectives of this t...
