a Schematic illustration of BAT transplantation (Created in BioRender. Baer, L. (2025) https://BioRender.com/0c6k2kp); b Ejection fraction, c left ventricular posterior wall thickness (LVPW), d hypertrophy index and e systolic and f diastolic function in aged male and female mice. n = 8 (sham males), n = 7 (+BAT males), n = 10 (sham females), n = 11 (+BAT females)-group. Data are expressed as mean ± SEM. Two-tailed P values by unpaired Student’s t test (b–f). Bar colors: white (sham), blue (+BAT males), red (+BAT females) (b–f).
