Feasibility of Reduced-Dose Posttransplant Cyclophosphamide and Cotransplantation of Peripheral Blood Stem Cells and Umbilical Cord-Derived Mesenchymal Stem Cells for SAA

Scientists evaluated the effectiveness and safety of reduced-dose cyclophosphamide, 20 mg/kg for 13 patients in matched sibling donor hematopoietic stem cell transplantation (HSCT) cohort and 25 mg/kg for 22 patients in haplo-HSCT cohort, on days +3, +4 combined with cotransplantation of peripheral blood stem cells and human umbilical cord-derived MSCs for severe aplastic anemia (SAA).

A Surge of DNA Damage Links Transcriptional Reprogramming and Hematopoietic Deficit in Fanconi Anemia

Investigators found that reprogramming transcription during hematopoietic differentiation resulted in an overload of genotoxic stress, which caused aborted differentiation and depletion of Fanconi anemia mutant progenitor cells.

PRDM8 Reveals Aberrant DNA Methylation in Aging Syndromes and Is Relevant for Hematopoietic and Neuronal Differentiation

Researchers analyzed blood samples of 70 aplastic anemia (AA) and 18 dyskeratosis congenita (DKC) patients to demonstrate that their epigenetic age predictions were overall increased, albeit not directly correlated with telomere length. Aberrant DNA methylation was observed in the gene PRDM8 in DKC and AA as well as in other diseases with premature aging phenotype, such as Down syndrome and Hutchinson-Gilford-Progeria syndrome.

Single UM171-Expanded Cord Blood Transplant Can Cure Severe Idiopathic Aplastic Anemia in Absence of Suitable Donors

Investigators report the first case of an adult patient with severe aplastic anemia who was successfully transplanted with a UM171‐expanded cord blood graft. After a conditioning of rabbit anti‐thymocyte globulin, fludarabine, cyclophosphamide and total body irradiation, a UM171 expanded graft of 3.29 x 106 CD34+ cells/kg was infused.
