In mammals, the monoblast-promonocyte-monocyte differentiation occurs in bone marrow, with monoblasts and promonocytes being detected in circulating blood only in specific pathological situations (Van Furth, 1989, 1992).
Monoblasts and promonocytes are included in the blast count as blast equivalents, while monocytes are excluded.
