Fetal stem cell research definition means embryonic stem cell research, where as their name suggests, are derived from embryos/foetus. Most embryonic stem cells are derived from embryo from eggs that have been fertilized in vitra ( in an in vitra fertilization clinic ) and then donated for research purposes with informed consent of the donor. To know more about fetal stem cell research definition we must know first how are embryonic stem cells grown in the laboratory. Growing cells in the laboratory is known as cell culture, Human embryonic stem cells (hESCs) are generated by transferring cells from a preimplantation-stage embryo into a plastic laboratory culture dish that contains a nutrient broth known as culture medium. The cells divide and spread over the surface of the dish.
The method of generating an embryonic stem cell line is considerably inefficient, so lines are not produced each time cells from the preimplantation-stage embryo are placed right into a culture dish. Nevertheless, if the plated cells survive, divide and multiply enough to crowd the dish, they’re eliminated gently and plated into a number of recent tradition dishes. The method of re-plating or subculturing the cells is repeated many occasions and for many months. Every cycle of subculturing the cells is known as a passage. As soon as the cell line is established, the original cells yield thousands and thousands of embryonic stem cells. Embryonic stem cells which have proliferated in cell culture for for a protracted period of time without differentiating, and are pluripotent are known as an embryonic stem cell line At any stage within the course of, batches of cells can be frozen and shipped to other laboratories for additional culture and experimentation.
