text: The major difference between embryonic and somatic stem cells is that embryonic stem cells have the potential to differentiate into all cell types of the body, as they are pluripotent stem cells (cells that are able to differentiate into three primary germ cell layers of the early embryo and, thus, into any cell type of the body); whereas, it is believed that somatic stem cells can differentiate only into different cell types present in the tissue of their origin.
text: Pluripotent stem cells, i.e. cells that can give rise to any fetal or adult cell type, can be found in a number of tissues, including umbilical cord blood.
text: The NIH modified the definition to say that human embryonic stem cells "are cells that are derived from the inner cell mass of blastocyst stage human embryos, are capable of dividing without differentiating for a prolonged period in culture, and are known to develop into cells and tissues of the three primary germ layers.
text: These include embryonic stem cells, cells derived from the germ layers (mesoderm, ectoderm, endoderm), and cells formed during the early stages of embryonic stem cell differentiation.
text: Both papers independently identified four genes used to reprogram human somatic cells to pluripotent stem cells, which are cells that have the ability to develop into any specialized cell type making up the body.
text: Embryonic stem cells are the cells in the early stages of the embryo.
text: Embryonic stem cells are the cells within the protective layer of the blastocyst.
