Figure 6. Cell flow phenotypic results of the adherent culture of umbilical cord tissue in C57 mice. (A) The positive rate of CD29 was 99.6%. (B) FITC isotype control. (C) The CD90 positive rate was 99.7%. (E) The positive rate of CD34 was 0.109%, which is in line with the phenotypic characteristics of mouse mesenchymal stem cells. (D) and (F): PE isotype control.
