Abstract: The authors observed during their medical practice in the filed of micro anatomy that there is a structural heterogeneity of placenta villosities during gestation and a discrepancy in the classic literature regarding the perenity of cytotrophoblast layer. The structural heterogeneity of placenta villosities is determined by the tissue interrelationships; an important role is played by the mesenchym stem cells, the cytotrophoblast stem-like cells and last but not least by the processes of vasculogenesis and angiogenesis.
