Abstract:
:Human embryonic neutrophils (N) in the liver (from 8.5 mm crown-rump length) are alkaline phosphatase (AP) negative during the first trimester of pregnancy. Early bone marrow granulocytes (from eleventh to sixteenth weeks of gestation) behave similarly. Only a small percentage of slightly AP positive cells could be found. Occasional cells with strong NAP reaction appear in the second trimester. NAP positivity greatly increases in the third trimester and term-babies have a somewhat higher than normal NAP activity in circulating blood. Unlike NAP reaction, naphthol-AS-D-chloroacetate esterase and peroxidase reactions are positive even in the earliest (AP negative) neutrophils.
