Viscoelastic hydrogel regulation of organoid patterning and vascularization

Abstract

Disclosed herein are spinal cord models including a cell scaffold including methacrylated hyaluronic acid (HAMA) and dopamine-modified hyaluronic acid (HA-Cat), and a spinal cord spheroid or organoid or a fragment thereof cultured on the cell scaffold. Said spinal cord spheroids or organoids or fragments thereof can be co-cultured with blood vessel spheroid organoids to form blood-spinal cord barrier models. Also disclosed herein are methods of making and using said models.
