Targeting the YAP‐BST2 Axis Overcomes Intrinsic Anti‐PD‐1 Resistance in Metastatic Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Concurrent YAP hyperactivation and Tp53 loss in Atp4b‐expressed parietal cell lineage drives gastric cancer initiation, multi‐organ metastasis, and intrinsic resistance to anti‐PD‐1 therapy. BST2 emerges as a direct YAP‐TEAD transcriptional target that engages PIRA2 on myeloid cells to establish an immunosuppressive microenvironment.

Umbilical Cord Blood-Derived CD34 Cells Improve Outcomes of Traumatic Brain Injury in Rats by Stimulating Angiogenesis and Neurogenesis

open access: yesCell Transplantation, 2014
Human umbilical cord blood cells (HUCBCs) have been shown to be beneficial in reducing neurological deficits in rats with brain fluid percussion injury (FPI). This study aimed to assess the basic mechanisms underlying the neuroprotective effects of HUCBC-

EPC-CFA profiles of HUCB CD34+ cells and mixed CD34+ and CD34− cells.

open access: yes, 2014
(A) Morphology of small EPC-CFUs and large EPC-CFUs derived from HUCB CD34+ cells (Scale bar = 20 µm). (B) EPC differentiation and expansion potentials were estimated by quantification of the 2 types of EPC-CFU clusters in CD34+ cell-derived EPC-CFUs and

TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

open access: yesAdvanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

Integrated Multi‐Omics Reveals Cellular States and Microenvironmental Remodeling in Coexisting DCIS and IDC

open access: yesAdvanced Science, EarlyView.
Coexisting DCIS and IDC samples are profiled using spatial transcriptomics, single‐cell RNA sequencing, and single‐cell DNA sequencing. Integrative multi‐omics analysis reveals distinct malignant epithelial and microenvironmental features between DCIS and IDC, which are further validated using Xenium and multiplex immunohistochemistry.

The magnitude of exercise‐induced progenitor cell mobilisation and extravasation is positively associated with cardiorespiratory fitness

open access: yesExperimental Physiology
CD34+ progenitor cells with angiogenic capabilities traffic into blood during exercise and extravasate afterwards but the magnitude of this response varies between people.

Segregation of late outgrowth endothelial cells into functional endothelial CD34- and progenitor-like CD34+ cell populations.

open access: yes, 2014
Late outgrowth endothelial cells (OECs) that originate from peripheral blood mononuclear cells ex vivo have phenotypic and functional properties of mature endothelial cells.

CXCL3 Antagonism Reverses Systemic Antitumor Immune Memory Impairment Associated With High Tumor Burden and Sensitizes Anti‐PD‐1 Therapy

open access: yesAdvanced Science, EarlyView.
This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

open access: yesAdvanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

Exosomes derived from human CD34+ stem cells transfected with miR-26a prevent glucocorticoid-induced osteonecrosis of the femoral head by promoting angiogenesis and osteogenesis

open access: yesStem Cell Research & Therapy, 2019
Background Damaged endothelial cells and downregulated osteogenic ability are two key pathogenic mechanisms of glucocorticoid (GC)-induced osteonecrosis of the femoral head (ONFH).
