Abstract: Tissue Interrelations in the Evolution of Hemochorial Barriers. Implications in Forensic Expertise of Pregnancy and Abortion: Homo Sapiens Sapiens placenta is of hemochorial type. In pregnancy evolution there is a phenotype transformation of villous structures. Therefor, we shall move from hemobichorial – maternoembrionar type to hemomonochorial – maternofetal type.The authors have noticed the structural differences between the two villous types through the evaluation of tissue interrelations in between hemochorial barriers differentiating the fibrinoid and villous elements of extracellular matrix. The existence of PAS positive and fibrinoid storage are the main factors for accumulating calcar salts in citotrofoblast location.Those observations are important in the medical expertise because they bring arguments upon the changes that come in disturbing maternofetale circulation.
