Article Abstract
Cellular senescence is a well-established driver of aging and age-related diseases. There are many challenges to mapping senescent cells in tissues such as the absence of specific markers and their relatively low abundance and vast heterogeneity. Single-cell technologies have allowed unprecedented characterization of senescence; however, many methodologies fail to provide spatial insights. The spatial component is essential, as senescent cells communicate with neighboring cells, impacting their function and the composition of extracellular space. The Cellular Senescence Network (SenNet), a National Institutes of Health (NIH) Common Fund initiative, aims to map senescent cells across the lifespan of humans and mice. Here, we provide a comprehensive review of the existing and emerging methodologies for spatial imaging and their application toward mapping senescent cells. Moreover, we discuss the limitations and challenges inherent to each technology. We argue that the development of spatially resolved methods is essential toward the goal of attaining an atlas of senescent cells.

Background: Atherosclerosis, a leading cause of cardiovascular disease (CVD) mortality worldwide, is characterized by dysregulated lipid metabolism and unresolved inflammation. Macrophage-derived foam cell formation and apoptosis contribute to plaque formation and vulnerability. Elevated serum galectin-3 (Gal-3) levels are associated with increased CVD risk, and Gal-3 in plaques is strongly associated with macrophages.

Triple-negative breast cancers (TNBCs) lack predictive biomarkers to guide immunotherapy, especially during early-stage disease. To address this issue, we used single-cell RNA sequencing, bulk transcriptomics, and pathology assays on samples from 171 patients with early-stage TNBC receiving chemotherapy with or without immunotherapy. Our investigation identified an enriched subset of interferon (IFN)-induced CD8 T cells in early TNBC samples, which predict immunotherapy nonresponsiveness.

The poor prognosis constitutes a significant difficulty for spinal cord injury (SCI) individuals. Although mesenchymal stem cells (MSCs) hold promises as advanced therapy medicinal products (ATMPs) for SCI patients, challenges such as Good Manufacturing Practice-compliant manufacturing, cellular senescence, and limited therapeutic efficacy continue to hinder their clinical translation. Recent advances have identified botanical nanovesicles (BNs) as potent bioactive mediators capable of "priming" MSCs to self-rejuvenate, augment paracrine effect, and establish inflammatory tolerance.

Background: The dysregulation of long-chain noncoding RNAs (lncRNAs) causes several complex human diseases including neurodegenerative disorders across the globe.
Methods And Results: This study aimed to investigate lncRNA expression profiles of Withania somnifera (WS)-treated human neuroblastoma SK-N-SH cells at different timepoints (3 & 9 h) and concentrations (50 & 100 µg/mL) using RNA sequencing. Differential gene expression analysis showed a total of 4772 differentially expressed lncRNAs, out of which 3971 were upregulated and 801 were downregulated compared to controls.

Ovarian granulosa cells (GCs) are pivotal for follicular homeostasis, and their dysregulated apoptosis drives age-related ovarian aging. The Hippo signaling pathway, modulated by long noncoding RNAs (lncRNAs), is implicated in regulating GCs proliferation and ovarian aging. TEAD2 (Transcriptional Enhanced Associate Domain 2), a key downstream transcription factor of the Hippo signaling pathway, plays a critical role in regulating cell proliferation, apoptosis, and embryonic stem cell self-renewal.
