FIG. 6.
Chemotaxis of human perivascular stem cells cultured with ECM. Undifferentiated human perivascular stem cell motility was modulated by (A) brain ECM, (B) spinal cord ECM, and (C) urinary bladder ECM as determined by quantification of migrated cells in a transwell assay. After 3 h, cell migration increased as much as 600% over control for urinary bladder ECM (100 μg/mL), 230% for brain ECM (100 μg/mL), and 160% for spinal cord ECM (100 μg/mL). Concentrations are μg protein per mL ECM solution. *p<0.05 by one-way ANOVA with Tukey–Kramer post hoc analysis.
