Hematopoietic stem cells are defined by their ability to self-renew and differentiate through progenitor cell stages into all types of mature blood cells. Gene-targeting studies in mice have demonstrated that many genes are essential for the generation and function of hematopoietic stem and progenitor cells. For definitively analyzing the function of these cells, transplantation studies have to be performed. In this chapter, we describe methods to isolate and transplant fetal liver cells as well as how to analyze donor cell reconstitution. This protocol is tailored toward mouse models where embryonic lethality precludes analysis of adult hematopoiesis or where it is suspected that the function of fetal liver hematopoietic stem and progenitor cells is compromised.

Glucose phosphate isomerase (GPI) deficiency caused by GPI gene mutations is a rare heterogenous condition that causes hereditary non-spherocytic hemolytic anemia (HNSHA). Patients who suffer from severe anemia may need more effective treatment. Here, clinical data and genetic testing results of two cases of HNSHA with GPI mutations treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT) were retrospectively analyzed.

Splenomegaly is a quite common clinical feature of Philadelphia (Ph) negative chronic myeloproliferative neoplasms (MPNs) and its presence may, in some cases, drives treatment decision. Most importantly, palpable splenomegaly is a minor criterion for both pre-fibrotic/early primary myelofibrosis and primary myelofibrosis (PMF) diagnosis, even if clinical assessment by physical examination is poorly reliable and accurate. On the other hand, despite the International Working Group-Myeloproliferative Neoplasms Research and Treatment and European LeukemiaNet guidelines defined spleen response criteria by palpation, they also recognized the highly subjective nature of spleen size assessment by physical examination, and recommended objective confirmation of volume reduction via computed tomography or magnetic resonance imaging (MRI).

Inhibition of DEK restores hematopoietic stem cell function in Fanconi anemia.

Hematopoietic stem cells (HSCs) are susceptible to replication stress, which is a major contributor to HSC defects in Fanconi anemia (FA). Here, we report that HSCs relax the global chromatin by downregulating the expression of a chromatin architectural protein, DEK, in response to replication stress. DEK is abnormally accumulated in bone marrow (BM) CD34+ cells from patients with FA and in Fancd2-deficient HSCs.

Introduction: -rearrangements define a subclass of acute leukemias characterized by a distinct gene expression signature linked to the dysfunctional oncogenic fusion proteins arising from various chromosomal translocations involving the (also known as ) gene. Research on the disease pathomechanism in -rearranged acute leukemias has mainly focused on the upregulation of the stemness-related genes of the -family and their co-factor .

Results: Here we report the and fusion gene-dependent downregulation of , a TGF-β signaling axis transcription factor.
