Scientists used FACS to discover and isolate common myeloid progenitor cells from other bone marrow cells. What assumption did they rely on for FACS isolation? Myeloid progenitor cells divide more quickly when compared to other bone marrow cells. Myeloid progenitor cells are less likely to be rejected by the immune system compared to other bone marrow cells. Myeloid progenitor cells have a unique cell surface protein when compared to other bone marrow cells.
