In vitro neurite growth from bone marrow mesenchymal stem cells (BM-MSCs). Cells were cultured for 7 days in media alone (cont) or media supplemented with 10% CSF from E19, E20, and P1 CSF or 10 ng/ml basic fibroblast growth factor (b-FGF) as the positive control. Neurite length was measured for at least 10 representative cells from each of 6 wells for each age of CSF tested. The E19 treated cells had greater density and neurite length compared to the E20 and P1 treated cells. **; P<0.01 and ***; P<0.001 compared to the control culture.
