ABSTRACT
While many investigators have described the biochemical and physiological similarities between tumor cells and trophoblast cells, in this discourse we will compare primarily their leucocytes, which constitute a large portion of the tumor and its microenvironment as well as the placenta and its microenvironment. There is a remarkable similarity between the cells that support placental growth and development and tumor growth and development. In many cases over half of the cells present in the tumor and the placenta are non-tumor or nontrophoblast cells, immune cells. Most of these immune cells are prevented from attacking the fetal derived placental cells and the self-derived tumor cells. Nevertheless, these leucocytes, in our opinion, are very active and support tumor and placental cell growth through the production of growth factors and angiogenic factors. These cells do this by activating the portion of the immune response which initiates and helps control tissue repair.
