The hematopoietic
stem cells (HSCs) are the blood cells which give rise to the myeloid and lymphoid
lineages. HSCs also have a potential to transdifferentiate into various nonhematopoietic cell
lineages especially neural lineage. [21] [Figure1] Bone marrow mesenchymal stem cells
(BMMSCs) give rise to mesodermal lineage cells such as osteoblasts, chondrocytes, adipocytes,
and muscle cells along with neuroectodermal cells
