Noncompetitive transplantations of whole BM cells from the moribund mice with MPN recapitulated the disease in lethally irradiated mice (Fig. 4a–j), with a shortened latency, ranging from 233 to 405 days (Supplementary Table 1), suggesting that the Gadd45g deficiency-induced MPN is transplantable. Here, GADD45G is linked to myeloproliferative neoplasm.
