What are embryonic stem cells?

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. read more

Embryonic stem cells, as their name suggests, are derived from embryos. Most embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro—in an in vitro fertilization clinic—and then donated for research purposes with informed consent of the donors. read more

Generation of embryonic stem cells. Embryonic stem cells are derived from embryos. They are specifically obtained from eggs that have been fertilized in vitro for an infertile couple in an in-vitro fertilization clinic. These are excess fertilized eggs that are donated for research with informed consent of the donors. read more

Embryonic stem cells (ES cells) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage preimplantation embryo.[1][2] Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. read more

Embryonic stem cells that have proliferated in cell culture for six or more months without differentiating, are pluripotent, and appear genetically normal are referred to as an embryonic stem cell line. read more

Embryonic stem cells possess the capacity to divide for long periods and retain their ability to make all cell types within the organism. These are termed pluripotent stem cells.
