Fabrication of Graphene Oxide Aerogel to Repair Neural Tissue

: The neural tissue engineering has been designed as a subset of tissue engineering for treating congenital malformations and accident injuries, particularly for individuals requiring tissue grafting. Such transplants, usually performed as autografting, can often not meet the requirements of an effective scaffold used in nerve tissue engineering. A novel neural tissue scaffold was introduced here to solve the problem concerning the reduced graphene oxide. The three-dimensional graphene oxide in the neural canal restricts the formation of fibroglandular tissues and facilities neural stem cell proliferation and growth. In these techniques, graphene oxide aerogel was initially made. Then, the freeze-drying process was used to fix the geometry of reduced graphene oxide hydrogels prepared using graphene oxide dispersion and ethylenediamine and gain aerogels. The X-ray diffraction patterns, FTIR and morphological related to samples were examined, followed by conducting in-vitro micropropagation and 4, 6-diamidino-2-phenylindol (DAPI) staining in fibroblast and P19 cultures. The results from immunofluorescence staining demonstrated the neural differentiation of P19 cells. It can be concluded that most cells attached to and differentiated on the scaffold surface and axons can penetrate randomly through them. Finally, the three-dimensional graphene oxide was proposed as an ideal alternative to be used in neural tissue engineering.
