Patterns of CD38, CD90, and AC133 expression on 11 cases of CD34+ acute leukemia were determined. The cases are numbered as in Table 3. The percentage of leukemia cells expressing CD38 or CD90 is shown and compared with the level of AC133 expression on the leukemia blast population. The pattern of CD90 and AC133 expression on CD38− and CD38+ fractions of the leukemia cells was similar in each case (data not shown).
