Hematopoietic stem cells are cells within the bone marrow.  Erythrocytesplatelets and all the white cells of the immune system are derived from these hematopoietic stem cells.  As such these cells are often referred to as pluripotent hematopoietic stem cells.

Hematopoietic stem cells can divide to produce a common lymphoid progenitor cell, or a common myeloid progenitor cell.  Cells that are derived from a common lymphoid progenitor cell include B cells, T cells and NK cells.  Cells that derive from a common myeloid progenitor include platelets, erythrocytes and granulocytes [1].
