Poly(lactic-co-glycolic) Acid/Nanohydroxyapatite Scaffold Containing Chitosan Microspheres with Adrenomedullin Delivery for Modulation Activity of Osteoblasts and Vascular Endothelial Cells

Table 2

Density and porosity of scaffolds with and without CMs.

	Apparent density (g/mL)	Porosity (%)
PLGA/nHA	0.045±0.017	90.81±0.87
PLGA/nHA/CMs	0.083±0.020^∗	88.93±0.32

∗P < 0.05 indicates statistically significant difference compared with the PLGA/nHA group.
