Expression of TER119 and transferrin receptor in ES-derived erythroblasts.

Flow cytometry for TER119 and transferrin receptor expression was described in “Materials and methods.” (A) The wild-type primitive erythroblasts. (B) Alas2-null primitive erythroblasts. (C) The wild-type definitive erythroblasts. (D) Alas2-null definitive erythroblasts. TER119 expression is shown on the ordinate (y-axis), while transferrin receptor expression is shown on the abscissa (x-axis).
