α-SMA production detected by immunofluorencence. (a-d) Immunofluorescence staining photos of corneal α-SMA expression separately from control group, uMSCsinj FK group, FK group and vehicleinj FK group. White arrow, α-SMA expression at the pericorneal vascular region due to vascular wall smooth muscle cells staining. Red circle, corneal lesion area. The α-SMA was labeled by FITC, n = 4.
