TUNEL and DAPI staining- Quantification of apoptotic nuclei. In TNFα-treated HUVECs (30 ng/mL 24 h), dual staining shows a good correlation between morphological apoptotic features determined by nuclear condensation and fragmentation (DAPI in blue, A, C) and DNA fragmentation (green, B, C). Bar graph (D) represents the means ± SD of apoptotic nuclei count in 5 fields (between 700 and 900 nuclei counted) of a representative experiment. *p = 0.0332 (Control vs TNFα). **p = 0.002 (Control vs TNFα + COVID+ HDL). #p = 0.03 (TNFα + control HDL vs TNFα + COVID+ HDL).
