WebChronic lymphocytic leukemia (CLL) is characterized by the clonal expansion of CD5 + CD23 + B cells in blood, marrow, and second lymphoid tissues. Gene-expression profiling and phenotypic studies suggest that CLL is probably derived from CD5 + B cells similar to those found in the blood of healthy adults. WebSep 6, 2024 · Chronic lymphocytic leukemia - Flow cytometry Flow cytometry shows a population of CD19+ cells with aberrant CD5 co-expression (black arrow). These have dim kappa expression (red arrow), dim CD20 expression (curved arrow), and positivity for CD23 (yellow arrow) and CD200 (green circle). CD10 and CD79b are both negative.
