What progenitor gives rise to both neutrophils and monocytes?

The correct answer is the granulocyte-monocyte progenitor (GMP). This progenitor is specifically responsible for the development of both neutrophils and monocytes, which are crucial components of the innate immune system.

The hematopoietic process begins with hematopoietic stem cells (HSCs) that can differentiate into various lineages. As HSCs differentiate, they can give rise to common lymphoid progenitors (CLPs) and common myeloid progenitors (CMPs). From the CMP, the GMP is derived, which then further differentiates into granulocytes, including neutrophils, as well as monocytes.

Understanding this lineage is essential when studying hematopoiesis and the immune response, as neutrophils and monocytes play pivotal roles in inflammation and the body's defense mechanisms. The other answer choices refer to different progenitors and do not provide the same lineage specificity for both neutrophils and monocytes as found in the GMP.
