Abstract
Bone marrow stromal cells (BMSC) normally give rise to bone, cartilage, and mesenchymal cells. Recently, bone marrow cells have been shown to have the capacity to differentiate into myocytes, hepatocytes, and glial cells. We now demonstrate that human and mouse BMSC can be induced to differentiate into neural cells under experimental cell culture conditions. BMSC cultured in the presence of EGF or BDNF expressed the protein and mRNA for nestin, a marker of neural precursors. These cultures also expressed glial fibrillary acidic protein (GFAP) and neuron-specific nuclear protein (NeuN). When labeled human or mouse BMSC were cultured with rat fetal mesencephalic or striatal cells, a small proportion of BMSC-derived cells differentiated into neuron-like cells expressing NeuN and glial cells expressing GFAP.
