Abstract Aim: The present study was designed to investigate the effects of chitosan/poly vinyl alcohol scaffold incorporated by NRBE (neonatal rat brain extract) on neuronal differentiation of P19 EC (embryonal carcinoma) stem cells.
Material and Methods: In order to induce neuronal phenotype, P19-derived embryonic carcinoma stem cells were cultured on a rat chitosan/poly (vinyl alcohol) scaffold with newborn rat brain extracts. To evaluate the survival potential, migration and differentiation of the three-dimensional culture cells, these cells were grafted to the developing central nervous system of the chick embryo. Finally, the transplanted cells were detected using specific staining and immunofluorescence methods.
Results: Cresyl-Violet specific staining confirmed the neuronal phenotype of the transplantation cells. Also, the expression of specific neural protein, synaptophysin, was shown using the immunofluorescence process.
Conclusion: The results of this study showed that P19 embryonic carcinoma stem cells can be used as a source of pluripotent cells in transplantation studies in order to investigate cellular and molecular aspects of developmental and cellular differentiation.
