To test whether either 9a+NRAS- and NRAS-induced blood diseases might harbour LSCs, we performed transplant experiments using the standard allograft procedure employed in published zebrafish AML model studies (Fang et al., 2021; Le et al., 2007; Wang et al., 2023; Xu et al., 2020; Zhao et al., 2018). The gene discussed is NRAS; the disease is acute myeloid leukemia.
