Fig. 1From: Dual functional construct containing kartogenin releasing microtissues and curcumin for cartilage regenerationMicroparticle (MP) characterization. a Scanning electron microscopy (SEM) images of MPs show their smooth surface morphologies. The mean diameter of the particles was 11 ± 5.5 μm. b Kartogenin (KGN) release profile from MPs for 32 days. Data are expressed as mean ± standard deviation (n = 3)Back to article page
