Morphology and identification of hWJMSCs at passage 3.

hWJMSCs at passage 3 were injected into the nerve conduit to support axonal growth. (A) Morphology of passage 3 hWJMSCs under an inverted microscope showing spindle-shaped cells. Scale bar: 100 µm. (B) Flow cytometry results showed expression percentages of CD45, CD29, CD105, and CD34 as 0.2%, 35.3%, 99.5%, and 0.0%, respectively. Therefore, the cells were identified as hWJMSCs. hWJMSCs: Human umbilical Wharton jelly mesenchymal stem cells.
