BACKGROUND:Neural stem cel s with self-proliferation and differentiation potential are the ideal seed cel s for central nervous tissue engineering. Although col agen and silk fibroin as biological scaffold materials have been widely used, both of them used alone have certain shortcomings. Is it possible to combine the two materials to build a novel neural tissue-engineered scaffold? What is the effect of this novel scaffold on the growth and differentiation of neural stem cel s? OBJECTIVE:To observe the growth and differentiation of neural stem cel s seeded onto the novel composite scaffold. METHODS:The rat embryonic neural stem cells were inoculated onto new composite scaffolds, and then, their growth and differentiation were observed by light microscopy and scanning electron microscopy. Neural stem cells were cultured in conventional suspension culture as control group. Cell counting kit-8 assay was used to detect viability of neural stem cells in the two groups. Three-dimensional composite scaffolds carrying neural stem cells were slic ed into paraffin sections to observe the growth and differentiation of neural stem cells by hematoxylin-eosin staining and immunofluorescence staining. RESULTS AND CONCLUSION:Neural stem cel s cultured on the new composite scaffold grew and differentiated wel , and interconnected synapses were observed. Cel counting kit-8 assay showed that neural stem cel s on the scaffold grew wel , and the cel viability was significantly higher in the composite scaffold group than that in the control group (P<0.05). Hematoxylin-eosin staining and immunofluorescence staining of paraffin sections further provided evidence for good growth and differentiation of neural stem cel s on the scaffold. These results indicate that the novel composite scaffold with good biocompatibility benefits the growth and differentiation of neural stem cel s, promising a favorable application prospect.

BACKGROUND:The traditional method of preparing tissue-engineered conduit has the defects of complex shape manufacturing and uncontrolable inner space structure, which cannot meet the requirements of some micro-catheters.
OBJECTIVE:To prepare a bionic spinal catheter and analyze its performance.
METHODS:The data model of the conduit was established using Solid Works software, and platform scan path was generated onthree-dimensionalprinter to produce the bionic spinal catheter with fibroin and colagen as raw materials. Then the water absorption, porosity, mechanical properties and celular compatibility of the conduits were detected. Next, the conduits were implanted into the subcutaneous tissue of rats and taken out at 1, 2, 3 and 4 weeks after surgery, respectively, to observe the degradation.
RESULTS AND CONCLUSION:The porosity of the conduit was (53.6±1.0)%, the water absorption was (1347±19.4)%, and the compression modulus was (0.60±0.12) MPa. The micropores distributed uniformly with different size ranging from 10 to 240 μm. Spherical or fusiform stem cels survived in the pores and densely adhered to the conduit with pseudopodia. The degradation rate ofthe conduit was 20%, 59%, 74%and 100% at 1, 2, 3 and 4 weeks after surgery, respectively. These findings indicate that the artificial bionic spinal catheter has good biocompatibility and degradability.
