Embryonic stem cell. Also called ES cells, embryonic stem cells are cells derived from the inner cell mass of developing blastocysts. An ES cell is self-renewing (can replicate itself), pluripotent (can form all cell types found in the body) and theoretically is immortal.tem cells that can give rise to all cell types that are found in an embryo, fetus, or developed organism, including the embryonic components of the trophoblast and placenta required to support development and birth.
After birth, most production is limited to red bone marrow in specific regions, but some white blood cells are produced in lymphoid tissue. All types of formed elements develop from a single cell type -- stem cell (pleuripotential cells or hemocytoblasts).Seven different cell lines, each controlled by a specific growth factor, develop from the hemocytoblast.hen a stem cell divides, one of the daughters remains a stem cell and the other becomes a precursor cell, either a lymphoid cell or a myeloid cell. These cells continue to mature into various blood cells. A leukemia can develop at any point in cell differentiation.
