The Department of biology in the College of Education for Pure Sciences organized a scientific forum entitled (Trophoblasts), which was hosted by the lecturer (Prof. Dr. Alaa Hussein Al-Safi) in the Department of biology. The audience was a group of lecturers and researchers interested in this topic. Its aim was to demonstrate and explain the trophoblast cells that they have a round shape with dark nuclei and they pushed towards the decidual tissue of the uterine mesenteric and there was strong evidence that the trophoblast cells had spread among the cells of the decidual tissue and had reached the cells of the walls of blood vessels, blast cells The trophoblast grows in the decidual tissue of the uterus, and its growth, spread and invasion of the tissue is responsible for the intimate interaction between the blastocyst and the endometrium. We wish more creativity and progress in the field of scientific activities aimed at serving our dear college, and from God Almighty, success and payment.
