A novel multicellular model of the adult mouse sinoatrial node retains spontaneous electrical activity and enables live investigation of the S100B-associated cell population

Dissociated adult mouse sinoatrial node cultures stay spontaneously electrically active beyond ten days on MEA arrays and, on compliant hydrogels, permit live tracking of heterogeneous S100B-EGFP-labeled cells.

Reduced LANCL1-AS1 in old human skeletal muscle diminishes mitochondrial activity, shortens mt-mRNA poly(A) tails, and suppresses myogenesis

The paper identifies LANCL1-AS1 as a lncRNA that declines with age in human skeletal muscle, reduces mitochondrial activity, and impairs myogenesis by shortening mt-mRNA poly(A) tails.

SenCat: Cataloging human cell senescence through multiomic profiling of multiple senescent primary cell types

SenCat catalogs senescence markers across 14 human cell types using transcriptomic and proteomic profiling, revealing shared metabolic pathways and enabling machine learning-based identification of senescent cells.

Senolytic treatment with fisetin reverses age-related endothelial dysfunction partially mediated by SASP factor CXCL12

Single-cell aortic transcriptomics and plasma bioassays in aged mice show that intermittent fisetin treatment clears senescent endothelial cells and reverses endothelial dysfunction partially driven by circulating CXCL12.

Integrative single-cell analysis of neural stem/progenitor cells reveals epigenetically dysregulated interferon response in progressive multiple sclerosis
