Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Lean, Healthy Controls

Subjects with a body mass index (BMI) of 25 or less will have a fat tissue biopsy collected

Group Type ACTIVE_COMPARATOR

Fat Tissue Biopsy

Intervention Type PROCEDURE

If subjects are scheduled for a surgical procedure a fat sample will be collected during the beginning of the surgery. If subjects are not scheduled for a surgical procedure, a small sample of subcutaneous (superficial) fat tissue from subjects abdomen area will be collected.

Obese, Non-Diabetic

Subject with a BMI between 30 and 50 kg/m2 will have fat tissue biopsy collected

Group Type EXPERIMENTAL

Fat Tissue Biopsy

Intervention Type PROCEDURE

If subjects are scheduled for a surgical procedure a fat sample will be collected during the beginning of the surgery. If subjects are not scheduled for a surgical procedure, a small sample of subcutaneous (superficial) fat tissue from subjects abdomen area will be collected.
