Patterns of Invasive Growth In Vitro. Human Decidua Graviditatis Confronted With Established Human Cell Lines and Primary Human Explants

摘要: Human decidua graviditatis was used as a receptor tissue to demonstrate invasive properties of human cells in vitro. In the confrontation between and established cell lines tumors normal origin well primary explanted cells, we noted differences cells' interactions with decidual tissue. The two original tumor lines, HeLa (carcinoma) AFi (sarcoma), spontaneously transformed lymphoblastoid line showed aggressiveness, i.e., invasion, rapid proliferation, injury, destruction Strain S3 FL (amnion) Girardi Heart, which are regarded because their increased mitotic rate polyploidy, exhibited various degrees aggressiveness but did not invade. Freshly fetal lung endometrium caused no injury were included
