  1. Legend: Samples 2, 10, 21 and 22 had null Mitotic Index (MI=0). Complex karyotypes are highlighted in bold character in the table (N=7). L1: acute lymphoblastic leukemia type 1; L2: acute lymphoblastic leukemia type 2; L3: acute lymphoblastic leukemia type 3. inv - inversion; mar – marker chromosome; t – translocation; i – isochromosome; add – additional chromosome; dup – duplication; der – derivative chromosome; Ph+ - Philadelphia chromosome; del – deletion; p – short arm of the chromosome; q – long arm of the chromosome, [ ] cells number analyzed.
