Inflammation And Contractility Are Altered By Obstructive Sleep Apnea Children's Serum, In Human Embryonic Stem Cell Derived Cardiomyocytes Academic Article uri icon


  • Nuclear-Factor-κB (NF-κB) is a transcription factor and a major regulator of inflammation and immune processes in several pathologies. We have previously reported over-expression of NF-κB classical subunits p65 and p50 in tonsils of children with OSAS. In addition, incubation of several cell lines with serum from OSAS children induces NF-κB activation and its translocation to the nucleus. In order to investigate NF-kB activation and the physiology of cardiomyocytes of human origin, we have established an ex-vivo model where human cardiomyocytes derived from human embryonic stem cells were incubated with OSAS and control sera. Serum samples were drawn at the morning following polysomnography (PSG) from children with PSG proven OSAS (AHI> 5) or Methods: children with normal PSG. Human cardiomyocytes were derived from the human embryonic stem cell H-9.1 clone …
