Abstract (original English)

Background Unhealthy dietary practices, sedentary life style and lack of physical exercise in developing countries like India are major contributors of metabolic syndrome like obesity and diabetes. Obesity in Indians is defined at Body Mass Index (BMI, kg/m 2 ) >25 and characterized as metabolically obese. Objective A preliminary study performed to explore ramification of obesity on metabolic profile of adipose tissue and adipose derived stem cells (ADSC) from control and obese Indians. Methods Adipose tissue/lipoaspirates from both control (BMI ≤ 23) subjects, and non-diabetic obese Indians subjects (BMI ≥ 25), were scrutinized for expressions of lipogenic genes, inflammatory mediators, stored adipokine levels, and insulin signaling proteins. Further, hADSC were isolated and immune-phenotyped from both the subject groups. Comparative assessments between chADSC and ohADSC were carried out for growth kinetics, expressions of pluripotent genes, adipogenic transcriptional factors, RUNX2, inflammatory mediators (IM), insulin signaling proteins, adipogenic and osteogenic differentiation. Results Adipose tissue of obese subjects depicted high leptin and resistin levels with reduced adiponectin levels. Expressions of IM and insulin signaling proteins were elevated compared to those of control subjects. hADSC of obese subjects demonstrated diminished proliferation, altered pluripotent
