Monocytes come from the myeloid lineage in the bone marrow and circulate in the blood. When they migrate into tissues, they differentiate into macrophages or dendritic cells, which are key antigen-presenting cells that help initiate and shape the immune response. While other myeloid cells like neutrophils and eosinophils stay as their respective granulocytes, and lymphocytes come from the lymphoid lineage, only monocytes give rise to macrophages and dendritic cells. That makes monocytes the best answer for this description.
