Zinc enhances the cell adhesion, migration, and self-renewal potential of human umbilical cord derived mesenchymal stem cells

Figure 6 Effect ZnCl₂ on adhesion ability of human umbilical cord-derived mesenchymal stem cells. A: Images of human umbilical cord (hUC)-derived mesenchymal stem cells (MSCs) of the control group and 20 µM ZnCl₂ treated groups at 0 min, 15 min, 30 min, 1 h, and 2 h of cell seeding. Bright, rounded, and freely floating cells represent unadhered cells while dark cells represent adhered cells; B: Significant increase was observed in the adhesion ability of hUC-MSCs of the treated group after 15 min (^bP ≤ 0.01), 30 min (^aP ≤ 0.05),1 h (^bP ≤ 0.01), and 2 h (^cP ≤ 0.001). An independent sample t-test was performed to analyze results, and data were represented as mean ± SD (n = 3).
