Article Snippet: After LPS stimulation (10 μg mL −1 , 12 h, ServiceBio, GC205009 ) to induce an inflammatory phenotype, cells were treated with hydrogel extracts (Hy, AdHy, AdHy@Pae) for 24 h. Cells were then washed twice with PBS, harvested, and fixed overnight at 4 °C in 70% cold ethanol; after washing, they were stained with 500 μL cell-cycle staining solution (MULTI SCIENCES, CCS012) for 30 min in the dark.
