Thrombopoietin Agonism to Promote Platelet Engraftment Following Hematopoietic Stem Cell Transplantation: Promising, but Not Ready for Primetime
In this issue of TCT, Fu and colleagues report the results of a randomized clinical trial conducted in China comparing thrombopoietic support using recombinant human thrombopoietin (rhTPO) with observation to promote platelet engraftment in patients receiving haploidentical hematopoietic stem cell transplantation (HSCT) with post-transplantation cyclophosphamide for the treatment of severe aplastic anemia (SAA).1 The trial enrolled 55 patients, randomized 1:1 to rhTPO or observation. The authors report successful hematopoietic reconstitution in all patients, but significantly faster platelet engraftment in patients randomi...

Cellular strategies to induce immune tolerance after liver transplantation: Clinical perspectives
World J Gastroenterol. 2024 Apr 7;30(13):1791-1800. doi: 10.3748/wjg.v30.i13.1791.ABSTRACTLiver transplantation (LT) has become the most efficient treatment for pediatric and adult end-stage liver disease and the survival time after transplantation is becoming longer due to the development of surgical techniques and perioperative management. However, long-term side-effects of immunosuppressants, like infection, metabolic disorders and malignant tumor are gaining more attention. Immune tolerance is the status in which LT recipients no longer need to take any immunosuppressants, but the liver function and intrahepatic histol...

A Deeper Depth of Response After Salvage Therapy Improves Outcomes of Autologous Stem Cell Transplantation in Relapsed Lymphoma and the Feasibility of Non-controlled Rate Freezing of Peripheral Blood Stem Cells
Conclusion High-dose therapy and autologous stem cell transplantation in low- to middle-income countries are limited to relatively younger patients, potentially curative conditions such as lymphoma, and predominantly after achieving a complete response to salvage therapy due to limited resources. Due to these factors, our study shows excellent response rates and survival outcomes compared to internationally published data. Engraftment was also excellent and comparable to published data despite the non-controlled rate freezing of peripheral blood stem cells.PMID:38659569 | PMC:PMC11039573 | DOI:10.7759/cureus.56851 (Source: Cancer Control)

BAG3 regulates cilia homeostasis of glioblastoma via its WW domain
Building on our previously identified and novel deciliating function of BAG3, we further decipher the molecular mechanisms of BAG3-regulated cilia homeostasis in glioblastoma (GBM). Based on identification of BAG3 interactomes and the contribution of different functional domains we now demonstrate that BAG3 regulates cilia homeostasis via its WW domain and modulation of YAP1 activity/downstream YAP1-dependent signaling. We also provide evidence for a complex interaction network of BAG3 with several pathways regulating cilia homeostasis at the level of ciliogenesis and cilium degradation. AbstractThe multidomain protein BAG...

In Memoriam: Prof. Makio Ogawa
Dr. Makio Ogawa, a pioneer and trailblazer in stem cell research, passed away on February 6, 2024, at his home in New Hampshire, just after celebrating his 84th birthday with a spirited online game of Go (a game much like checkers); his wife Mary-Jane found him peacefully at rest after he did not respond to a routine lunchtime call.

Exosomes From Human Umbilical Cord Stem Cells Suppress Macrophage-to-myofibroblast Transition, Alleviating Renal Fibrosis
This study investigates their potential to lessen renal fibrosis by targeting macrophage-to-myofibroblast transformation (MMT), a key driver of fibrosis.  We employed a mouse model of unilateral ureteral obstruction (UUO) and cultured cells exposed to transforming growth factor-β (TGF-β) to mimic MMT. HucMSC-Exos were administered to UUO mice, and their effects on kidney function and fibrosis were assessed. Additionally, RNA sequencing and cellul ar analysis were performed to elucidate the mechanisms by which HucMSC-Exos inhibit MMT. HucMSC-Exos treatment significantly reduced kidney damage and fibrosis in UUO mice. Th...

The genome of the colonial hydroid Hydractinia reveals that their stem cells use a toolkit of evolutionarily shared genes with all animals [RESOURCES]
Hydractinia is a colonial marine hydroid that shows remarkable biological properties, including the capacity to regenerate its entire body throughout its lifetime, a process made possible by its adult migratory stem cells, known as i-cells. Here, we provide an in-depth characterization of the genomic structure and gene content of two Hydractinia species, Hydractinia symbiolongicarpus and Hydractinia echinata, placing them in a comparative evolutionary framework with other cnidarian genomes. We also generated and annotated a single-cell transcriptomic atlas for adult male H. symbiolongicarpus and identified cell-type marker...

Systematic mapping of TF-mediated cell fate changes by a pooled induction coupled with scRNA-seq and multi-omics approaches [METHODS]
Transcriptional regulation controls cellular functions through interactions between transcription factors (TFs) and their chromosomal targets. However, understanding the fate conversion potential of multiple TFs in an inducible manner remains limited. Here, we introduce iTF-seq as a method for identifying individual TFs that can alter cell fate toward specific lineages at a single-cell level. iTF-seq enables time course monitoring of transcriptome changes, and with biotinylated individual TFs, it provides a multi-omics approach to understanding the mechanisms behind TF-mediated cell fate changes. Our iTF-seq study in mouse...

Insights into treatment of complex Crohn's  perianal fistulas
AbstractComplex perianal fistula is a common complication of Crohn ’s disease (CD) which leads to negative impact on patient’s quality of life. Successful management of the disease requires a multidisciplinary approach, including a gastroenterologist and a colorectal surgeon, applying combined surgical and medical therapy. One of frequently practiced surgical p rocedures is seton placement in the fistula tract, which is used to control perianal sepsis and drain the fistula, while preventing recurrent abscess formation.Darvadstrocel, a suspension of expanded, allogeneic, adipose-derived, mesenchymal stem cells, is safe ...

Alternative pre-mRNA splicing in stem cell function and therapeutic potential: A critical review of current evidence
Int J Biol Macromol. 2024 Apr 22;268(Pt 1):131781. doi: 10.1016/j.ijbiomac.2024.131781. Online ahead of print.ABSTRACTAlternative splicing is a crucial regulator in stem cell biology, intricately influencing the functions of various biological macromolecules, particularly pre-mRNAs and the resultant protein isoforms. This regulatory mechanism is vital in determining stem cell pluripotency, differentiation, and proliferation. Alternative splicing's role in allowing single genes to produce multiple protein isoforms facilitates the proteomic diversity that is essential for stem cells' functional complexity. This review delves...

Pediatric acute promyelocytic leukemia and Fanconi anemia: Case report and literature review
We report a 4 year-old boy from non-consanguineous parents diagnosed with standard risk APL. This child had café-au-lait spots and an extra thumb remnant. Genomic sequencing revealed two PV in FANCD1/BRCA2 confirming a diagnosis of FA-D1. Chromosomal breakage studies were compatible with FA. Each parent carried one variant and had no personal history of cancer. Morphological then molecular remissions were achieved with all-trans retinoic acid and Arsenic trioxide. This patient underwent haploidentical stem cell transplant. In addition to our patient, a literature search revealed four additional patients with APL/FA, with ...

GFRA4 improves the neurogenic potential of enteric neural crest stem cells via hedgehog pathway
CONCLUSION: GFRA4 promotes proliferation and differentiation but inhibits apoptosis of ENCSCs via the hedgehog pathway in HSCR.IMPACT: This study confirms that GFRA4 improves the proliferation and differentiation of ENCSCs via modulation of the hedgehog pathway. This study for the first time revealed the role and the mechanism of the action of GFRA4 in HSCR, which indicates that GFRA4 may play a role in the pathological development of HSCR. Our findings may lay the foundation for further investigation of the mechanisms underlying HSCR development and into targets of HSCR treatment.PMID:38658664 | DOI:10.1038/s41390-024-031...
