Long-Term Hematopoietic Stem Cells as a Parasite Niche during Treatment Failure in Visceral Leishmaniasis

[Communications Biology] Double bioluminescent/fluorescent Leishmania infantum and L. donovani reporter lines enabled the identification of long-term hematopoietic stem cells as a niche in the bone marrow with remarkably high parasite burdens, a feature confirmed for human hematopoietic stem cells.

Kinetics of Disappearance and Appearance of Isoagglutinins A and B after ABO-Incompatible Hematopoietic Stem Cell Transplantation

[Bone Marrow Transplantation] In a one-year follow-up, data of 136 ABO-incompatible hematopoietic stem cell allogeneic transplanted patients were studied, of which 60 had major, 61 minor and 15 bidirectional incompatibility.

Acute Kidney Injury within 100 Days Post Allogeneic Hematopoietic Cell Transplantation Is Associated with Increased Risk of Post-Transplant Complications and Poor Transplant Outcomes

[Bone Marrow Transplantation] Researchers investigated the incidence of AKI and its impact on transplant outcomes among 408 patients transplanted at Princess Margaret Hospital Cancer Centre, Toronto, Canada.

Impaired Immunosuppressive Role of Myeloid-Derived Suppressor Cells in Acquired Aplastic Anemia

[Haematologica] Myeloid-derived suppressor cells (MDSCs) populations were evaluated in acquired aplastic anemia in which aberrant immune mechanisms contributed to bone marrow destruction.

CKS1 Inhibition Depletes Leukemic Stem Cells and Protects Healthy Hematopoietic Stem Cells in Acute Myeloid Leukemia

[Science Translational Medicine] Researchers studied the role of cyclin-dependent kinase regulatory subunit 1 (CKS1)–dependent protein degradation in primary human acute myeloid leukemia and healthy hematopoiesis xenograft models in vivo.

Successful Outcomes of Second Hematopoietic Stem Cell Transplantation for Graft Failure in Pediatric Patients with Severe Aplastic Anemia

[Scientific Reports] The authors analyzed 10 cases of second hematopoietic stem cell transplantation (HSCT) to treat severe aplastic anemia pediatric patients who suffered from graft failure and concluded that second haploidentical family donors HSCT is an effective treatment.

Decoding Lymphomyeloid Divergence and Immune Hyporesponsiveness in G-CSF-Primed Human Bone Marrow by Single-Cell RNA-Seq

[Cell Discovery] Through unbiased bioinformatics analysis, the authors showed the alterations in the transcriptional landscape of hematopoietic cells in granulocyte colony-stimulating factor (G-CSF)-primed bone marrow, and revealed that G-CSF-induced myeloid-biased differentiation initiated from the stage of lymphoid-primed multipotent progenitors.

Endothelial and Hematopoietic hPSCs Differentiation via a Hematoendothelial Progenitor

[Stem Cell Research & Therapy] Two hESCs and one hiPSC lines were differentiated into a hematoendothelial population, hPSC-ECs and blast colonies via CD144+-embryoid bodies.

Hematopoietic Differentiation Persists in Human iPSCs Defective in De Novo DNA Methylation

[BMC Biology] Researchers investigated if DNA methyltransferase 3A is essential for hematopoietic differentiation of human induced pluripotent stem cells (iPSCs).

Evaluating Immune Response and Metabolic Related Biomarkers Pre-Allogenic Hematopoietic Stem Cell Transplant in Acute Myeloid Leukemia

[PLoS One] Scientists identified patients with acute myeloid leukemia who underwent hematopoietic stem cell transplantation and had existing baseline plasma samples. Using those samples, they studied 65 blood based metabolomic and 61 immune/inflammatory related biomarkers, comparing patients with either long-term overall survival (OS) or short-term OS.

Hematopoiesis of Indeterminate Potential and Atherothrombotic Risk

[Thrombosis and Haemostasis] The authors explore the relationship between mutations in genes causing clonal hematopoiesis of indeterminate potential (CHIP) and atherothrombotic disorders, along with potential mechanisms of enhanced clonal outgrowth and potential therapies and strategies to slow CHIP progression.

Hyaluronic Acid–GPRC5C Signaling Promotes Dormancy in Hematopoietic Stem Cells

[Nature Cell Biology] Using single-cell RNA sequencing, scientists showed a continuous landscape of highly purified human bone marrow hematopoietic stem cells displaying varying degrees of dormancy.
