Printing, and possessed higher resolution [67]. Laser bioprinting can be made use of to deposit BMSCs directly in vivo to improve osteogenesis. Keriquel et al. devised a method to print nano-Hydroxyapatite (nHA) layers directly onto a mouse essential 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 further 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 significant osteogenesis than the ring shaped BMSC nHA. It is actually hypothesized that due to the disk cell homogeny and proximity, the BMSCs secreted paracrine elements to induce osteogenic differentiation [69]. This novel method should be explored in higher depth with various biomaterials and BMSCs to gauge its full potential. A summary of each bioprinting method and its effects on ADSCs and BMSCs is provided in Table two.Table 1. Bioprinting tactics.

Effects of bioprinting methods on adipose and bone marrow stem cells. Bioprinting Approach Extrusion Drop in viability because of shear stress, cells can attach to hydrogels normally and grow, printed monolayers show a higher cell viability, retention of differentiation potential Sheer anxiety may possibly encourage cells into osteoblast lineage, long-term differentiation prospective is retained, reduced cell viability, cell proliferation increases inside 28 days Inkjet Favorable cell adhesion depends upon the biomaterial, improve in cell proliferation immediately after 24 h, may well build incomplete constructs as a result of printing decrease cell densities Cell proliferation and viability impacted by larger pressures, medium shear pressure encourages differentiation, unchanged stem cell phenotype post printing, osteogenic differentiation not impacted by printing Laser
