- W4387157678 abstract "Over the last few years, 3D bioprinting has emerged as a promising approach in the field of regenerative medicine. This technique allows for the production of three-dimensional scaffolds to support cell transplantation due to its ability to mimic the extracellular environment. One alternative to enhancing cell adhesion, survival and proliferation is the use of decellularized extracellular matrix as a bioink component. The aim of this study was to produce a bioink using lyophilized rat Decellularized Spinal Cord Tissue (DSCT) for 3D bioprinting of nervous tissue. DNA quantification, hematoxylin and eosin and DAPI staining indicated that 1% SDS and 9 hours processing were effective in removing the cells from the spinal cord samples. The cell viability assay showed that the decellularized matrix is not cytotoxic for PC12 cells. The hydrogel containing DSCT, alginate, and gelatine used as the base for the bioink has a shear thinning behavior and low G''/G' ratio, allowing for good printability without compromising cell viability after 3D bioprinting. The bioink supported long-term PC12 cell survival, with 93% of live cells 4 weeks after printing, and stimulated the production of laminin-1 and neurofilament-M. This bioink, therefore, represents an easily available biomaterial for central nervous system tissue engineering." @default.
