For example, senescent T-cells are accumulated in visceral adipose tissues in obesity 67 and produce proinflammatory cytokines, leading to chronic inflammation, metabolic disorders, and cardiovascular diseases 68,69
Reported benefits (per available research): Studied in rat full-thickness wound models for accelerating skin repair, with one study reporting reepithelialization increased by up to 61% over controls by day 7, along with greater wound contraction and collagen deposition (Malinda et al., animal study, 1999) Studied in rodent models of ischemic myocardial injury for reducing post-infarct scarring and supporting cardiac tissue repair
Results vary by individual based on health factors and treatment response
