Abstract

Here, we examine whether neurons differentiated from transplanted stem cells can integrate into the host neural network and function in awake animals, a goal of transplanted stem cell therapy in the brain. We have developed a technique in which a small “hole” is created in the inferior colliculus (IC) of rhesus monkeys, then stem cells are transplanted in situ to allow for investigation of their integration into the auditory neural network. We found that some transplanted cells differentiated into mature neurons and formed synaptic input/output connections with the host neurons. In addition, c-Fos expression increased significantly in the cells after acoustic stimulation, and multichannel recordings indicated IC specific tuning activities in response to auditory stimulation. These results suggest that the transplanted cells have the potential to functionally integrate into the host neural network.

Abstract

A facile and environmentally friendly route has been put forward for fabricating regenerated cellulose-based composite films (RC) with graphene oxide addition (GO). Nanocomposite films prepared through the solution blending method of cellulose solutions to a reversible ion solvent system of dimethyl sulfoxide, 1,8-diazabicyclo [5.4.0] undec-7-ene, carbon dioxide (DMSO/DBU/CO2) that contained a nano-additive of GO dispersion in DMSO. The results demonstrated that the addition of GO had a significant impact on the structural, mechanical, and gas barrier properties of the films. SEM and XRD results showed that GO was dispersed in cellulose solution uniformly. The evident red-shift of the characteristic functional groups in the Fourier transform infrared spectroscopy (FT-IR) spectra also indicated the interaction between GO and cellulose matrix. With 5 wt % GO, the oxygen permeability coefficient of corn cellulose films decreased from 1.59 × 10−12 cm3 cm cm−2 s−1 Pa−1 to 1.8 × 10−15 cm3 cm cm−2 s−1 Pa−1. Meanwhile, the thermal stability of corn cellulose film improved with the incorporation of GO.
