CD22 expression at relapse post-InO. CD22 expression in two patients evaluated pre- and post- InO and in one patient post-InO. CD22 is uniformly expressed on >99% B-lymphoblastic leukemia cells prior to InO (a, d); however, CD22 expression is diminished or absent (b, c, e) or absent in a subset of lymphoblasts (f) after InO
