Article Abstract
The timely mobilization of hematopoietic stem and progenitor cells (HSPCs) is essential for maintaining hematopoietic and tissue leukocyte homeostasis. Understanding how HSPCs migrate between bone marrow (BM) and peripheral tissues is of great significance in the clinical setting, where therapeutic strategies for modulating their migration capacity determine the clinical outcome. Here, we identify an epigenetic regulator, Phc2, as a critical modulator of HSPC trafficking. The genetic ablation of Phc2 in mice causes a severe defect in HSPC mobilization through the derepression of Vcam1 in bone marrow stromal cells (BMSCs), ultimately leading to a systemic immunodeficiency. Moreover, the pharmacological inhibition of VCAM-1 in Phc2-deficient mice reverses the symptoms. We further determine that Phc2-dependent Vcam1 repression in BMSCs is mediated by the epigenetic regulation of H3K27me3 and H2AK119ub. Together, our data demonstrate a cell-extrinsic role for Phc2 in controlling the mobilization of HSPCs by finely tuning their bone marrow niche.

The objective of this study was to evaluate the concentration and integrity index of circulating cell-free DNA (ccf-DNA) as biomarkers for the detection and monitoring of minimal residual disease (MRD) in pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL). Comparison with a validated methodology for the quantification of monoclonal rearrangements of the IGH gene was made. Peripheral blood and bone marrow samples were collected from 10 pediatric patients with B-ALL at diagnosis, remission, and maintenance phases.

Background: Neurotraumatic conditions, such as spinal cord injury, brain injury, and neurodegenerative conditions, such as amyotrophic lateral sclerosis, pose a challenge to the field of rehabilitation for its complexity and nuances in management. For decades, the use of cell therapy in treatment of neurorehabilitation conditions have been explored to complement the current, mainstay treatment options; however, a consensus for standardization of the cell therapy and its efficacy has not been reached in the medical community. This study aims to provide a comparative review on the very topic of cell therapy use in neurorehabilitation conditions in an attempt to bridge the gap in knowledge.

Two types of plasmacytoid dendritic cell (pDC) proliferation disease are acknowledged so far by the 5th edition of the World Health Organization Classification of Haematolymphoid Tumors: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) and mature pDC proliferation associated with myeloid neoplasms (MPDCP) in which pDC is part of the malignant clone. We aim to investigate pDC proliferation associated with non-myeloid acute leukemia (AL). A retrospective analysis of all cases admitted in our center with a diagnosis of non-myeloid AL from September 2020 to April 2023 was performed to select cases with pDCs greater than 2% of bone marrow by flow cytometry (FCM).

Lymphoma-associated hemophagocytic lymphohistiocytosis (LA-HLH) is a life-threatening hyperinflammatory syndrome, and hierarchical management based on a prognostic model is important. The endothelial activation and stress index (EASIX) score has demonstrated prognostic utility in recipients of allogeneic stem cell transplantation and chimeric antigen receptor (CAR) T-cell therapy. However, its role in LA-HLH remains unestablished.

Chronic myelomonocytic leukemia (CMML) is an aggressive hematologic neoplasm characterized by an expansion of CD123 monocytes and plasmacytoid dendritic cells (pDCs). pDC bone marrow clusters in CMML have been associated with higher rates of acute myeloid leukemia transformation. We evaluated tagraxofusp, a CD123-targeted therapy, in a phase 1/2 trial for patients with CMML.
