Adipose stem cells in scaffolds.

Biomaterial	Effects	Bioprinting Method *	References
Alginate	Increased BGLAP, COL1A1, SPP1 expression, round morphology, stiffness may encourage osteoblast differentiation, stemness preservation, low viability	Inkjet	[91,93,94]
Collagen	Osteogenic genes are upregulated with inhibition of TNF-α, enhanced in vivo bone regeneration, multipolar or bipolar morphology	-	[98,99,100]
Gelatin	Good cell proliferation and adhesion, ossification in vivo, enhance osteogenesis, early upregulation of OPN and RUNX2	-	[101,102,103,104]
Hyaluronic Acid	Can cause osteogenic, chondrogenic, or adipogenic differentiation, mineralized matrix formation and calcium deposition, long term cell preservation	-	[105,106,107]
Alginate/Collagen	High viability and cell proliferation	Custom	[108]
Collagen/Hyaluronic Acid	Strong cell proliferation, associated with chondrogenesis, greater hyaluronic concentration inhibits chondrogenesis	-	[109,110]
