Characterisation of long term cat placental explant cultures: uptake of taurine by system beta.

abstract：:The uterine endometrium responds to blastocyst implantation with extensive proliferation and differentiation of stromal cells into decidual cells, forming the antimesometrial and mesometrial decidua. These undergo regression by apoptosis but as this process occurs at different time periods suggest that there is spatia...
