Figure 2. SA-β-Gal staining of lung slices from COVID-19 and control patients. (A) SA-β-Gal staining (left) and HE staining (right) of four COVID-19 lungs and one control lung. We only found signs of senescence (blue staining) in lungs from individuals with very short telomeres (B) overview of detected SA-β-Gal activity within analyzed samples.
