Figure S1. Identification of Mesenchymal Stem Cells (MSCs)

MSCs were identified by marking positive with CD73 and CD90, and negative with CD45 and HLA-DR.

Figure S2. Quantitative test for Ethanolic extract of Astragalus (EEA)

EEA were reacted with 5% sodium nitrite and detected with an ultraviolet spectrophotometer. The absorbance was observed at 256nm, and a standard curve was drawn by the concentration of the standard product of EEA. X presents wavelength, Y standards absorbance. A: The spectrum drawn by the UV spectrophotometer. NC: normal control; Standard 1-4: the standard product of EEA; Raw: raw material; Sample1-4:EEA. B: The standard curve drawn with standard products of EEA.

Figure S3. Microvessel density test

A: CD31 antibody was used to stain the vascular cells. Immunofluorescence detection for CD31showed vascular cells increased after treatment of the mixture. Blue: DAPI; Green, CD31. B: Statistical analysis was performed for CD31+ cells and analyzed with ImagePro to evaluate the differences in mean vessel density.
