Cell-to-cell communication via Delta-Notch signaling is widely used in various tissues and organs to regulate development patterning; however, the mechanisms regulating Notch for precise cell fate decisions remain poorly understood. Similar mammals, intestinal stem cells (ISCs) adult Drosophila midgut generate both absorptive secretory progeny, guided by differential levels of activation. Here we performed a forward genetic screen identified glucosylceramide synthase (GlcT), rate-limiting...

Endothelial progenitor cells (EPCs) are important in tumor angiogenesis. Stromal cell-derived factor-1α (SDF-1α) and its receptor C-X-C chemokine type 4 (CXCR4) key stem cell homing. Melittin, a component of bee venom, exerts antitumor activity, however, the underlying mechanisms remain to be elucidated. The present study aimed assess effects melittin on EPCs angiogenesis mouse model osteosarcoma. UMR‑106 were treated with various concentrations viability was determined using MTT assay. EPC...

Human regulatory T cells (Tregs) have been reported to be not significantly different in the peripheral blood of patients with chronic obstructive pulmonary disease (COPD) and healthy controls. Recent research has identified some new markers for Tregs indicated that are composed distinct subpopulations. The aim study was describe changing patterns circulating Treg subpopulations acute exacerbation COPD (AECOPD) controls, explore their potential roles AECOPD pathogenesis. Blood samples were...

Amniotic epithelial stem cells (AESCs) are considered as potential alternatives to keratinocytes (KCs) in tissue-engineered skin substitutes used for treating damage. However, their clinical application is limited since similarities and distinctions between AESCs KCs remain unclear. Herein, a transcriptomics analysis functional evaluation were understand the commonalities differences KCs. RNA-sequencing revealed that involved multiple epidermis-associated biological processes shared by show...

<sec> <title>BACKGROUND</title> There are numerous symptoms related to cancer and its treatments that can affect the psychosomatic health quality of life patients with cancer. The use electronic symptom management systems (ESMSs) help monitor manage their effectively, improving health-related outcomes. However, patients’ adhesion ESMSs decreases over time, little is known about real experiences them. Therefore, it necessary gain a deep understanding ESMSs. </sec> <title>OBJECTIVE</title>...

ABSTRACT In recent years, cell segmentation techniques have played a critical role in the analysis of biological images, especially for quantitative studies. Deep learning-based models demonstrated remarkable performance segmenting and nucleus boundaries, however, they are typically tailored to specific modalities or require manual tuning hyperparameters, limiting their generalizability unseen data. Comprehensive datasets that support both training universal evaluation various essential...
