ABL1 and acute lymphoblastic leukemia: Of the CD34+CD10+CD19+CD79a+CD179a+ population, the numbers of lymphoid cells in the common ALL BCR/ABL+ patients were increased compared to the CD34+CD10+CD19−CD79a+CD179a+ and CD34+CD10+CD19+ populations, with no or single expression of CD79 or CD179a but were less significant than those in the common ALL BCR/ABL− patients.
