Stem cells are pluripotent, that is, they have the ability to differentiate and become any cell type in the body.

Stem cells come from newly fertilized eggs.
the embryo is killed
Stem cells are removed just after conception when the zygote is forming into an embryo. When stem cells are taken, the embryo cannot develop, and so does die.
In order to obtain stem cells, an embryo must be in the blastocyst stage.

There are more cells found in an embryo than an adult.
In order to obtain stem cells, an embryo must be in the blastocyst stage.
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
you do!
A stem cell is a cell that has the ability to generate itself into any body part or cell type of the organism it is developing. Stem cells are found in the blastocyst of an embryo and ALSO in adults. Because adults have already finished developing, the stems cells are then used to maintain regenerative organs such as skin, blood or intestinal tissues. All other adult cells do not have the ability to regenerate.
Embryonic stem cells (ES cells) are stem cells derived from the inner cell mass of the blastocyst, an early-stage embryo.In other words, they do not become embryos, they are part of an embryo.
Organogenesis is the process by which a mass of cells in a developing embryo differentiates and develops into a functioning organ. In the embryo, all cells are basically stem cells and all alike. Once the process of organogenesis takes place and the beginnings of specialized organs form, the fetal stage begins.
stem cells are described as cells part of the embryo where fertilized human egg cells have 23 pairs of chromosomes
