Printing, and possessed higher resolution [67]. Laser bioprinting may be used to deposit BMSCs straight in vivo to enhance osteogenesis. Keriquel et al. devised a approach to print nano-Hydroxyapatite (nHA) layers directly onto a mouse critical sized calvaria defect. The experimentation demonstrated laser exposure for the dura mater brought on temporary inflammation and no permanent tissue damage in mouse brain [68]. This was additional expanded by printing BMSCs in situ in a ring or disk geometry to induce osteogenesis in vivo. The in situ printed BMSC nHA disks showed considerable osteogenesis than the ring shaped BMSC nHA. It is actually hypothesized that resulting from the disk cell homogeny and proximity, the BMSCs secreted paracrine components to induce osteogenic differentiation [69]. This novel method should be explored in greater depth with distinctive biomaterials and BMSCs to gauge its full potential. A summary of each and every bioprinting technique and its effects on ADSCs and BMSCs is supplied in Table two.Table 1. Bioprinting tactics.

Effects of bioprinting methods on adipose and bone marrow stem cells. Bioprinting Approach Extrusion Drop in viability due to shear strain, cells can attach to hydrogels normally and develop, printed monolayers show a larger cell viability, retention of differentiation potential Sheer tension might encourage cells into osteoblast lineage, long-term differentiation possible is retained, lower cell viability, cell proliferation increases inside 28 days Inkjet Favorable cell adhesion will depend on the biomaterial, raise in cell proliferation soon after 24 h, may produce incomplete constructs on account of printing lower cell densities Cell proliferation and viability affected by greater pressures, medium shear stress encourages differentiation, unchanged stem cell phenotype post printing, osteogenic differentiation not affected by printing Laser
