Kaplan-Meier analysis of survival for CML and bcCML models. (A) Donor populations of purified HSCs, CMPs, or GMPs were infected with the BCR/ABL retrovirus and transplanted into primary mice. (B) Donor populations of purified HSCs, CMPs, or GMPs were infected with the BCR/ABL + Nup98/HoxA9 retroviruses and transplanted into primary mice. Numbers of recipients indicated in parentheses for each donor cell type. Days of survival after transplantation are indicated for each cell type on the x-axis.
