Morphological Assessment on the Placental Function

Abstract

This article contains the human placenta and chorionic diseases in the study of which the purpose is mainly concerned to find out, if possible, the correlation between placental functions and its fine structures under the light of current cytological, cytochemical and immunocytochemical technique. In this study extensive use of electronmicrographs has been made because we have considered it appropriate in order to understand cellular functions in connection with submicroscopic organelles. Themes dealt here are the structure of the placental surface using scanning electron microscope, growth and differentiation of trophoblast, intracellular identification of elements using transmission electron microscope in combination with X-ray microanalyser system, mechanism of secretion of the proteohormone, the site for enzyme activity and some other problems. Results obtained here are worthwhile to note however those still permit assessment by further investigation.
