Trophoblast turnover [122123

Like every epithelium, the villous trophoblast displays a continuous turnover comprising: 1 proliferation of cytotrophoblast stem cells,

2 differentiation of post-proliferative daughter cells (23 days),

3 syncytial fusion of these cells with the overlying syncy-tiotrophoblast,

4 further differentiation and maturation within the syn-cytiotrophoblast (3-4 weeks),

5 aging and late apoptosis at specific sites of the syncy-tiotrophoblast, and finally

6 packing of old material into syncytial knots and extrusion of membrane-sealed corpuscles into the maternal circulation.

That is why most women find out that they are pregnant only after one month of pregnancy.
