The invasiveness of tumor cells is one of the indicators for determining the degree of malignancy of the tumor. Placental amniotic membrane is translucent and has a simple structure. It can be used as a support for cancer cell culture and can be observed in the degree of invasion to the matrix. The purpose of this article is to observe the amniotic membrane by scanning electron microscopy. Structural and cancerous cell morphology changes in amniotic invasion. Materials and Methods Fresh term placenta, peel fetal amniotic membrane, wash, cut into 2 cm diameter disc, put
