Figure Lengend Snippet: Elimination of senescent cells with mGFD‐CD3 ameliorated age‐related phenotypes in mice. (A) ELISA analysis for TNF‐α and IL‐1β in blood samples collected from mice treated with mGFD‐CD3 or mCD3 at 3 Months. ( n = 5 for young group; n = 3 for mCD3 group; n = 3 for mGFD‐CD3 group). (B) ( left ) H&E staining of IAT samples collected from mice described in (a). Quantification of adipocyte areas ( right ). Each data point represents an individual mouse. Scale bar, 50 μm. (C) ( left ) Masson staining of liver and lung tissues collected from the mice described in (a). Black arrows indicate positive staining. Scale bar, 50 μm. ( right ) Quantification of the fibrotic areas of liver or lung tissues using Image J. (D) PAS staining of kidney samples from mice described in (a). Scale bar, 50 μm (original) and 15 μm (magnified). Quantification was achieved using Image J. (E) TRAP and Masson staining of femur samples from mice described in (a). Black arrows indicate positive staining. Scale bar, 50 μm. Quantification was achieved with Image J. Data are presented as mean ± SD and analyzed by one‐way ANOVA followed by Tukey's multiple comparisons test (A–E). * p ≤ 0.05.

Article Snippet: After 24 h of coculture, the supernatant was collected and used to determine the concentrations of IFN‐γ (Invitrogen, KHC4021) and TNF‐α (Proteintech, KE00154).
