Placental tissue. Coloured scanning electron micrograph (SEM) of a section through a human placenta at the syncytiotrophoblast layer. The syncytiotrophoblast layer forms the outermost foetal component of the placenta and contributes to its barrier function. Chorionic villi (finger-like projections) sprout from the outermost maternal layer (chorion) and are 'invaded' by the syncytiotrophoblasts. This increases the surface area available for nutrient exchange between the mother and the foetus | |
