(A) Western blot examining c-Myc in 104 HSCs/MPPs isolated from wild-type (+/+), Mx1-Cre+;Aarssti/sti;Mycfl/+ (sti/sti;Myc+/−) and Aarssti/sti (sti/sti;Myc+/+) mice.
(B) Diagram showing bone marrow transplantation strategy.
(C) Donor cell engraftment 16 weeks after 5 × 105 bone marrow cells from wild-type (+/+), Aarssti/sti (sti/sti;Myc+/+) and Mx1-Cre+;Aarssti/sti;Mycfl/+ (sti/sti;Myc+/−) mice were transplanted with 5 × 105 recipient-type bone marrow cells into irradiated mice. Total hematopoietic cells, B cell, T cell, and myeloid cell engraftment is shown (n = 4–8 donors and 26–44 total recipients/genotype).
(D) Donor cell engraftment in secondary recipients (n = 4–10 donors and 17–44 recipients/genotype).
(E) Frequency of secondary recipients in (D) that exhibited long-term multilineage reconstitution.
Data represent mean ± standard error of the mean. Statistical significance was assessed using a Student’s t test (C and D) or Fisher’s exact test (E). *p < 0.05; **p < 0.01; ***p < 0.001.
