The characteristics of smooth muscle progenitor cells. (a) Outgrowth of smooth muscle progenitor cells (SPCs) by using the phase contrast microscope. (b–d) Immunofluorescence staining of SPCs. The cells were incubated with anti-α-SMA (red) and anti-CD34 (green) antibodies, respectively, and then complexed with Alex 594 and 488 secondary antibodies. Cell nuclei were counterstained with DAPI (blue).
