Final answer:
Early arteriosclerotic lesions are indicated by immature neutrophils (band cells), while late lesions are indicated by lymphocytes.
Step-by-step explanation:
Early arteriosclerotic lesions are indicated by the presence of immature neutrophils in which the nucleus looks like a single "band." These cells are also known as band cells or stab cells. On the other hand, late arteriosclerotic lesions are indicated by the presence of lymphocytes. Lymphocytes are a type of white blood cell that play a role in the immune response.
