Next, to quantify LPCs and study their biology, Langenau and colleagues generated and transplanted MYC-induced T-cell acute lymphoblastic leukemia in the CG1 strain, a syngeneic fish generated by in vitro fertilization of eggs from a Golden strain female with ultraviolet-inactivated sperm and subjected to heat shock to produce gynogenetic diploid animals [32]. Here, MYC is linked to T-cell acute lymphoblastic leukemia.
