TET2 is a methylcytosine dioxygenase that regulates cytosine hydroxymethylation. Although there are extensive data implicating a pivotal role of TET2 in hematopoietic stem/progenitor cells (HSPCs), the importance of TET2 in bone marrow mesenchymal stromal cells (BMSCs) remains unknown. In this study, we show that loss of TET2 in BMSCs increases cell proliferation and self-renewal and enhances osteoblast differentiation potential of BMSCs, which may in turn alter their behavior in supporting HSPC proliferation and differentiation. In addition, Tet2 loss alters BMSCs in promoting Tet2-deficiency-mediated myeloid malignancy progression. Tet2 loss in BMSCs also dysregulates hydroxylation of 5-methylcytosine (5mC) and the expression of genes that are key for BMSC proliferation and osteoblast differentiation, leading to alteration of biological characteristics in vivo. These results highlight the critical role of TET2 in the maintenance of BMSC functions and osteoblast differentiation and provide evidence that dysregulation of epigenetic modifiers in BMSCs contributes to the progression of myeloid malignancies. TET2 loss in BMSCs increases cell proliferation and osteoblast differentiation TET2 loss in BMSCs increases hematopoietic supportive capacity of BMSCs TET2 loss in BMSCs accelerates Tet2-deficiency-mediated myeloid malignancy In this article, Zhao and colleagues demonstrated that TET2 plays an important role in regulating the behavior of BMSCs in addition to its intrinsic role in HSPCs to participate in aberrant hematopoiesis. Moreover, they also show that BMSCs are the most important niche cell components in Tet2−/− mice that contribute to the progression of Tet2-deletion-driven myeloid malignancies.
