Abstract
Scaffold-based bone tissue engineering strategies fail to meet the clinical need to fabricate patient-specific and defect shape-specific, anatomically relevant load-bearing bone constructs. 3D bioprinting strategies are gaining major interest as a potential alternative, but design of a specific bioink is still a major challenge that can modulate key signaling pathways to induce osteogenic differentiation of progenitor cells, as well as offer appropriate microenvironment to augment mineralization. In the present study, we developed silk fibroin protein and gelatin-based conjugated bioink, which showed localized presence and sustained release of calcium. Presence of 2.6 mM Ca 2+ ions within the bioink could further induce enhanced osteogenesis of Bone marrow derived progenitor cells (hMSCs) compared to the bioink without calcium, or same concentration of calcium added to the media, as evidenced by upregulated gene expression of osteogenic markers. This study generated unprecedented mechanistic insights on the role of fibroin-gelatin-CaCl 2 bioink in modulating expression of several proteins which are known to play crucial role in bone regeneration as well as key signaling pathways such as β-catenin, BMP signaling pathway, Parathyroid hormone-dependent signaling pathway, Forkhead box O (FOXO) pathway, and Hippo pathways in hMSC-laden bioprinted constructs.
