FIG. 2.

DDM liposomes promoted the chemotaxis of hDPSCs in a dose-dependent manner. DPSCs were seeded into Boyden transwell inserts, placed on liposome treatments (100 μg/mL), SFM, free DDM (10 μg/mL), or control (basal α-MEM) and allowed to pass through a 0.8 μm membrane for 48 h. Membranes were then fixed and stained with 0.1% (w/v) crystal violet, respective photos were taken (B) and recruited cells counted (A). n = 3 ± SEM significance indicated by *p < 0.05, **p < 0.01, and ****p < 0.0001 (unpaired Student's t-test compared to control). SFM, serum-free media. Color images available online at www.liebertpub.com/tea
