We are working on the testing of the developed UV-LED inks based on the gelatin methacrylate (GelMA) and other photocrosslinkable materials, also matrixes were printed with our own prototype of bioprinter and they were sowed with the rats fibroblasts. Our R&D team is working now on the testing of bio inks and building up the height of the printed scaffolds and follow-up cell survival studies.
