Figure 3: a) Fluorescence analysis of the miR126 NIR MB in CB-EPCs. The miR126 NIR MB (50 pmol) was transfected alone or with 100 pmol of miR126 antagomir into CB-EPCs. Cells only indicated the fluorescence intensity of CB-EPCs without the transfection of the miR126 NIR MB. Data were displayed as mean± standard error (*P<0.05). b) Confocal microscopy imaging (X800) of CB-EPCs transfected with the miR126 NIR MB. The miR126 NIR MB (0, 1, 20, and 50 pmol) was transfected alone or with 100 pmol of miR126 antagomir into CB-EPCs. All figures were merged with the 4′, 6-diamidino-2-phenylindole (DAPI) image (nucleus staining, 460 nm) and cellular morphology. c) Real time PCR of CB-EPCs from the wound healing. Intact CB-EPCs was used as a control. Data were displayed as mean ± standard error (*P<0.05). d) Confocal microscopy imaging (X800) of the miR126 NIR MB in CB-EPCs of the wound healing model. Dotted white lines highlighted the edges of a stripped region. Intact CB-EPC was used as a control. All figures were merged with the 4′, 6-diamidino-2-phenylindole (DAPI) image (nucleus staining, 460 nm) and cellular morphology.
