is it drive from animals too?
Yes, they are derived from the inner cell mass of the early embryo, which are harvested from the donor mother animal.
Embryonic stem cell

who sang johnny b good in back to the future UNANSWERABLE who is "michael j. fox"? Canadian-American actor, comedian, author, film producer, and activist. in which activism is he involved? His foundation, The Michael J. Fox Foundation, was created to help advance every promising research path to curing Parkinson's disease. is he involved in a stem cell related stream? His foundation focuses on the researches, including embryonic stem cell studies. what kind of study is it? UNANSWERABLE what are some of its adverse effects? The major concern with the possible transplantation of ESC into patients as therapies is their ability to form tumors including teratoma. what are its applications? Pluripotent stem cells have shown promise in treating spinal cord injuries, age related macular degeneration, diabetes, etc. any debate on its ethics? Since harvesting embryonic stem cells necessitates destroying the embryo from which those cells are obtained, the moral status of the embryo comes into question. describe how is it derive from humans? The first step would be The inner cell mass (cells of interest), from the blastocyst stage of the embryo, is separated from the trophectoderm, the cells that would differentiate into extra-embryonic tissue.

Embryonic stem cell [SEP] Derivation from other animals
Embryonic stem cells are derived from the inner cell mass of the early embryo, which are harvested from the donor mother animal. Martin Evans and Matthew Kaufman reported a technique that delays embryo implantation, allowing the inner cell mass to increase. This process includes removing the donor mother's ovaries and dosing her with progesterone, changing the hormone environment, which causes the embryos to remain free in the uterus. After 4–6 days of this intrauterine culture, the embryos are harvested and grown in "in vitro" culture until the inner cell mass forms “egg cylinder-like structures,” which are dissociated into single cells, and plated on fibroblasts treated with mitomycin-c (to prevent fibroblast mitosis).
