Neurosphere culture of HUCB p75NTR+ cells. Freshly isolated p75NTR+ and p75NTR− cell fractions were cultured in a neurosphere culture condition or in a mesenchymal stem cell (MCS) culture condition. (a) Representative images of each cell fraction. (b) Bromodeoxyuridine (BrdU) incorporation in p75NTR+ cell-derived spheres. (c) Immunocytochemical analysis of p75NTR+ cell-derived spheres. Arrows represent p75NTR+ small spheres. (d) Representative images of secondary and tertiary spheres. Scale bars represent 50 μm.
