In the sympathetic ganglia, satellite glial cells are one of three main types of cells, the other two being the sympathetic ganglion neurons and small intensely fluorescent (SIF) cells.
A stem cell is a type of cell that is nonspecific in its function; in contrast, for instance, to a heart or brain cell, which is functionally specific. There are two major sources of stem cells: embryonic stem cells and non-embryonic stem cells.Embryonic stem cells are obtained from 5- to 12-day old embryos.Although removal of a stem cell from an embryo kills the embryo, the stem cells are valued for their potential to produce any type of cell.hus, the heart of the stem-cell controversy centers on the aforementioned fact that the extraction of stem cells from 5- to 12-day embryos kills the embryo. But thatâs not the only issue: In addition, stem cells derived from an embryonic human may, in turn, reject the person who receives them.
