Task: Answer Verification
Input (English): Question: Does repopulation of apolipoprotein E knockout mice with CCR2-deficient bone marrow progenitor cells inhibit ongoing atherosclerotic lesion development?
Answer: In contrast to the critical role of CCR2 in the initiation of atherogenesis, bone marrow progenitor cell-derived CCR2 does not influence the progression of established atherosclerotic lesions, pointing to additional mechanisms for recruitment of monocytes at later stages of lesion development.
Output (English): no
