Chen et al. (2021) [41]	n Ce-BG/GelMA n = 0, 2, 5	The mean particle size of the 0 Ce-BG, 2 Ce-BG, and 5 Ce-BG was 362.8 nm, 389.42 nm, and 208.9 nm, respectively	Ce-BG powders were added at 1% w/v to a GelMA foam (10% w/v) and LAP (photoinitiator 0.1% w/v) solution. The solution was stirred for 1 h and they were cross-linked using 365 nm UV light for 20 s.
Hu et al. (2021) [43]	SIS/MBG@Exos	Mesoporous BG was used, no particle size mentioned	MBG was added to a neutralized SIS solution and blended, and sodium alginate (SA) was then added as a thickener. The solution was centrifuged; this slurry was used in an extrusion cryogenic 3D printing system to fabricate the scaffolds.
Kong et al. (2018) [46]	SA-BG-DFO-GDL	20.28 µm (90% < 34.86 µm)	0.02 g BG powders were added into 1 mL of SA solution (2 wt.%) with 0.01 g of GDL, followed by repeatedly pipetting in a syringe to generate homogeneous solution. Under the weak acid condition of GDL, both Ca and Si ions could be released from BG powders, and the released Ca ions contributed to the cross-linking of hydrogels.
Li et al. (2020) [48]	PAB and PABC	BG nanoparticles, no particle size mentioned	A PEGDA/BGN/C solution was mixed with SA solution, and then I2959 was added as photoinitiator. The solution was cross-linked at 365 nm for 5 min.
Li et al. (2022) [49]	SA/BG-MMP9-siNP	20 µm is the average particle size	2% w/v 45S5 BG and 2% w/v GDL powders were mixed with 1 mL of 2% SA solution. The resulting solution was homogenized and then placed into a mold for it to form the hydrogel.
Ma et al. (2020) [52]	SA/BG-SA (CM)-PLGA(PFD). CM = conditioned medium; PFD = Poly(9,9-di-n-dodecylfluorene)	Size ranges from 5 µm to 20 µm	1 mL of 2% (w/v) SA solution, 20 mg of BG powders, and 20 mg of GDL were manually mixed in an injector with a t-branch pipe to acquire a homogeneous solution. Then, the mixed solution was injected into a Teflon mold with a cylindrical shape. After 5 min, SA-2% BG hydrogels were obtained because the Ca2+ ions released from BG with the GDL presence caused the gelation of SA/BG.
Zhu et al. (2022) [56]	HQBn, where n corresponds to the percentage of magnesium present in the BG, n = 0, 2, 5, 10	Particle diameter is around 200 nm	HA-PBA and QCS were firstly dissolved in saline solution to obtain a precursor solution at a concentration of 2% (w/w). Then, QCS solution was added dropwise into HA-PBA solution according to the volume ratio of 1:1 under stirring, and gelation occurred within 1 min after mixing. The mixture was stirred for another 30 min to obtain a stable hydrogel (HQ). Similarly, HQB hydrogels were formed by mixing QCS and the mixture of HA-PBA and BGs.
Chen et al. (2019) [40]	Trilayer scaffold: chitosan/PVA/PVAnBG	Diameter around 800 nm	BG was incorporated by sequential electrospinning. Different ratios of nBG (5%, 10%, 20%, 40% wt.) were mixed with PVA and electrospun.
Gao et al. (2017) [42]	CPB and CP scaffolds. CPB: collagen, PCL (polycaprolactone), and BG. CP: collagen and PCL	Approximate size 100 nm	1:1:1 Col/PCL/BGNs blended solutions (4% w/w of each composition) were obtained by dissolving them in hexafluoroisopropanol (HFIP) under continuous stirring for 6 h. Nanofibrous scaffolds were obtained because of electrospinning this solution.
