Article Title: BoneMA – Synthesis and Characterization of a Methacrylated Bone-derived Hydrogel for Bioprinting of Vascularized Tissues

doi: 10.1101/2020.03.02.974063

Figure Lengend Snippet: Representative fluorescence microscopy image demonstrating the range of patterns and geometries achieved by printing HMSC-laden BoneMA with a DLP printer (Ember). The cells were stained with F-Actin (green) after printing to enable confirmation of the shape and structure of the printed constructs through fluorescence microscopy. (Scale – 750 μm)

Article Snippet: To that end, human dental pulp stem cells (HDPSC) and human mesenchymal stem cells (HMSC) were used to assess cytocompatibility and bioprintability, while green fluorescent protein (GFP)-expressing human umbilical vein endothelial cells (HUVECs) (cAP0001GFP, Angio-proteomie, USA) were employed to investigate the vasculogenic potential of the synthesized biomaterial.

Figure Lengend Snippet: Effects of ADO in the BM-MSC and GBM cell cross-talk. ( A ) The image depicts the contact-independent transwell cultures with BM-MSCs in the upper chamber and U343MG in the lower chamber. U343MG cell proliferation was evaluated after 24 and 48 h with Crystal violet, as reported in . ( B ) The image depicts the contact-independent transwell cultures with U343MG in the upper chamber and BM-MSCs in the lower chamber. BM-MSCs cell proliferation was evaluated after 48 h with Crystal violet, as reported in . ( C ) U343MG cells were seeded in the upper chamber and BM-MSCs treated with ADO (100 nM and 100 µM) in the lower chamber. After 24 h, U343MG cell invasion was analyzed using Matrigel basement membrane transwell system, as described in . Representative images are shown. Cell migration was quantified by counting the number of cells that migrated into the lower surface of the transwell membrane. The data are reported as percentage of cell invasion versus the CTRL set to 100% and are the means ± SEM of three independent experiments. The significance of the differences was determined by one-way ANOVA, followed by Bonferroni’s post-hoc test. * p < 0.05, ** p < 0.01, *** p < 0.001 vs. CTRL.
