Flow cytometry analysis on day 15 of EB differentiation revealed mild hematopoietic alterations in the G condition with an increase of monocytes (CD33+CD14+) (Fig. 1B–G), resembling the early manifestation of the disease previously reported in multiple GATA2-deficient patients who developed MDS and carried monosomy 713,19,29. Here, GATA2 is linked to myelodysplastic syndrome.
