Accumulating clinical and experimental evidence indicates that stem cells from various sources are promising in the treatment of cardiac dysfunction. They may be incorporated into neovascular foci and thus contribute to postnatal physiological and pathological vasculogenesis and/or produce a variety of growth factors for angiogenesis and cytokines that home other stem cells from other organs for cardiac regeneration. This review focuses on the neovascularization of stem cells from different sources in cardiac repair, with emphasis on adult stem cells.

Deciphering the complex clonal heterogeneity of polycythemia vera and the response to interferon alpha.

Interferon alpha (IFNa) is approved for the therapy of patients (pts) with polycythemia vera (PV), a subtype of myeloproliferative neoplasms (MPN). Some pts achieve molecular responses (MR), but clonal factors sensitizing for MR remain elusive. We integrated colony formation and differentiation assays with single-cell RNA seq and genotyping in PV-derived cells vs.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Definitive hematopoietic stem and progenitor cells (HSPCs) arise from a small number of hemogenic endothelial cells (HECs) within the developing embryo. Understanding the origin and ontogeny of HSPCs is of considerable interest and potential therapeutic value. It has been proposed that the murine placenta contains HECs that differentiate into HSPCs.

Toll-like receptor (TLRs) activation in multiple myeloma (MM) cells induces heterogeneous functional responses including cell growth and proliferation, survival or apoptosis. These effects have been suggested to be partly due to increase in secretion of cytokines such as IL-6 or IFNα among others from MM cells following TLR activation. However, whether triggering of these receptors also modulates production of immunoglobulin free light chains (FLCs), which largely contribute to MM pathology, has not been investigated in MM cells before.

Ten-eleven translocation (TET) enzymes oxidize 5-methylcytosine (mC) in DNA, contributing to the regulation of gene transcription. Diverse mutations of TET2 are frequently found in various blood cancers, yet the full scope of their functional consequences has been unexplored. Here, we report that a subset of TET2 mutations identified in leukemia patients alter the substrate specificity of TET2 from acting on mC to thymine.
