Question

Quizplus · Accepted Answer

ALL, or acute lymphoblastic leukemia, is a cancer of the lymphoid cells which give rise to B cells and T cells. CLP, or common lymphoid progenitor, is a type of stem cell that gives rise to both B cells and T cells. A defect in the CLP can lead to the development of ALL. CMP (common myeloid progenitor) gives rise to cells such as red blood cells, platelets, and granulocytes, which are not directly involved in the development of ALL. PSC (pluripotent stem cells) is a general term that can refer to both CLP and CMP, and lymphoblasts are immature lymphoid cells that can be involved in the development of ALL but are not the root cause of the defect.
