Since eccentric contractions produce passive mechanical tension, they stimulate sarcomerogenesis, which we observe as increases in muscle fascicle length in humans. Isometric contractions at short or moderate muscle lengths do not. https://t.co/7wVgBzjELC
A model that predicts cellular age from Cell Painting microscopy images alone. No DNA methylation needed. The model captures morphological aging hallmarks across nuclear and cytoplasmic compartments, correlates with chronological age AND epigenetic clocks. The promise: screen for rejuvenation compounds...
Epigenetic aging happens at different rates in individual cells within the same tissue. Using single-cell DNA methylation analysis, Hagit Masika, Tommy Kaplan, Howard Cedar, and colleagues show polycomb CpG island methylation creates 'young' vs 'old' cell subpopulations even at fixed...
