Article Abstract
Mechanisms determining intrinsic differentiation bias inherent to human pluripotent stem cells (hPSCs) toward cardiogenic fate remain elusive. We evaluated the interplay between ErbB4 and Epidemal growth factor receptor (EGFR or ErbB1) in determining cardiac differentiation in vitro as these receptor tyrosine kinases are key to heart and brain development in vivo. Our results demonstrate that during cardiac differentiation, cell fate biases exist in hPSCs due to cardiac/neuroectoderm divergence post cardiac mesoderm stage. Stage-specific up-regulation of EGFR in concert with persistent Wnt3a signaling post cardiac mesoderm favors commitment toward neural progenitor cells (NPCs). Inhibition of EGFR abrogates these effects with enhanced (>twofold) cardiac differentiation efficiencies by increasing proliferation of Nkx2-5 expressing cardiac progenitors while reducing proliferation of Sox2 expressing NPCs. Forced overexpression of ErbB4 rescued cardiac commitment by augmenting Wnt11 signaling. Convergence between EGFR/ErbB4 and canonical/noncanonical Wnt signaling determines cardiogenic fate in hPSCs.

Curvilinear Peri-Brainstem Hyperintense Signals as a Marker of Leptomeningeal Metastases in Lung Adenocarcinoma: A Multicenter Retrospective Case Series.

Unlabelled: Leptomeningeal metastasis (LM) is a severe complication of solid malignancies, including lung adenocarcinoma, characterized by poor prognosis and diagnostic challenges. This study assesses whether curvilinear peri-brainstem hyperintense signals on MRI are a characteristic feature of LM in lung adenocarcinoma patients.
Methods: This retrospective study analyzed data from multiple centers, encompassing lung adenocarcinoma patients with peri-brainstem curvilinear hyperintense signals on MRI between January 2016 and March 2022.

Severe aplastic anemia (SAA) is a life-threatening bone marrow failure syndrome that is caused primarily by immune-mediated destruction of hematopoietic stem cells. Traditional treatment relies on immunosuppressive therapy (IST) with antithymocyte globulin (ATG) and cyclosporine (CSA). However, the toxicity and limited availability of ATG have spurred interest in ATG-free regimens.

NSG-SGM3 humanized mouse models are well-suited for studying human immune physiology but are technically challenging and expensive. We previously characterized a simplified NSG-SGM3 mouse, engrafted with human donor CD34 hematopoietic stem cells without receiving prior bone marrow ablation or human secondary lymphoid tissue implantation, that still retains human mast cell- and basophil-dependent passive anaphylaxis responses. Its capacities for human antibody production and human B cell maturation, however, remain unknown.

This study highlights the biomedical relevance of injectable TS (tannic acid-silk fibroin)-Mg/Sr hydrogels in alveolar bone repair, particularly their prospective role as carriers for stem cells from the apical papilla (SCAPs) in tissue regeneration. By utilizing self-assembling silk material, noted for its favorable handling properties, we present a useful approach for single-wall bone defects, such as bone fenestration and fractures in the oral cavity. Furthermore, our findings regarding the involvement of the TRPM7 ion channel indicate a possible regulatory pathway for improving alveolar bone defect repair.

Background: Spinal cord injury (SCI) often leads to severe motor and sensory impairments, and current treatment methods have not achieved complete neural repair. In recent years, exosomes have become a research focus in the treatment of nerve injuries due to their important roles in intercellular information transfer, immune regulation, and neural repair. Our study conducts a scientometric analysis to map the research landscape related to exosomes in SCI.
