Immunofuorescence Image (image) Neural Regeneration Research Share Print E-Mail Caption This is an immunofuorescence image of oligodendrocyte precursor cells after differentiation induced by bone morphogenetic protein-4. Seven days later, the bodies of the glial fbrillary acidic protein-positive cells became larger and processes became thicker. These glial fibrillary acidic protein-positive cells presented many thin and long processes.
