MSC transmigrate through an endothelial monolayer towards kidney injury chemokine SDF-1α. a Schematic representation of the transwell assay to assess the capacity of MSC to transmigrate through a monolayer of endothelial cells. b MSC showed the capacity to transmigrate through a confluent endothelial monolayer towards SDF-1α. Injury of HUVEC enhanced the transmigration capacity of MSC, resulting in 54% of the added MSC transmigrating through the injured HUVEC monolayer after 6 h (n = 5). Results are shown as mean ± SD. Significance of the comparison between injured HUVEC + SDF-1α and non-injured HUVEC + SDF-1α is shown as *p value < 0.05
