ABSTRACT
Purpose:To explore the expression of human c kit receptor protein (c kit R, CD117) in acute leukemia (AL). The focus of the study was put on the value of the expression of c kit R in diagnosis for acute non lymphoid leukemia (ANLL).Methods:Flow cytometry (FCM) was used to determine the expression of the transmembrane c kit R on mononeuclear cell in bone marrow in 24 patients with acute lymphoid leukemia (ALL) and 47 patients with acute non lymphoid leukemia (ANLL). Results:There was no significant difference between expression of c kit in healthy individuals and patients with ALL. The expression of c kit in patients with ANLL was significantly higher than that of healthy individuals and that of patients with ALL ( P
ABSTRACT
The leukemic cellular surface antigens of 45 cases for ANLL and 36 cases of CML were detected and classified with a series of the domestic McAbs by immunoflurescent technique. The immunophenotype of ANLL was compared with its cellular morphologic classification. The difference of the surface antigens between the CML instable phase and the CML in blast crisis was analyzed. Four cases of acute leukemias (AL) which could not be classified morphologically were classified by McAbs. FAB M_1～M_5 could be divided into 3 phenotype groups: myeloblastic, promylocytic and promoncytic phenotype. The immunophenotype of ANLL tended to agree with its cellular morphologic classification. All 28 cases of CML in stable phase reacted with a neutrophil-McAb. However, there was no this antigen expression in 8 cases of CML in blast crisis. The immunophenotype of 4 cases of AL could be made with McAbs . Of these 4 cases. 3 were AL and 1 ANLL.
