The described protocol and associated video provide a step-by-step overview of a mini-liposuction technique to obtain subcutaneous adipose tissue samples from the abdominal area. This research group has performed a total of 124 biopsies over the course of 19 months with no adverse effects in participants. The procedure is safe and associated with minimum risk to participants or the biopsy team, provided that the described safety measures are followed. Aseptic technique (including opening and dispensing of sterile equipme...

Adipose tissue can provide useful information on the metabolic function of humans. Human subcutaneous adipose tissue is readily accessible. A technique for subcutaneous adipose tissue extraction was first described in the mid-80s1; since then, the initial protocol has been improved to increase the yield and improve study participant tolerability. Subcutaneous adipose tissue can be obtained from numerous sites, most commonly from the glutei1 and abdominal area2. Samples from the latter may be more desirable as they provide more valuable information in metabolic disease-related contexts3.
Subcutaneous adipose tissue biopsy using the mini-liposuction method can be safely and efficiently performed in a non-clinical setting. Following appropriate training by a board-certified physician and using strict aseptic technique, researchers can routinely perform these biopsies with minimal risk to both participant and investigators. The biopsy team must consist of at least 2 individuals: the person who will perform the biopsy and an assistant.
The person responsible for the biopsy is tasked with confirming the participant&#39;s identity, checking the participant can safely undergo the procedure (see protocol steps 2.1-2.4 below), ensuring the participant is comfortable throughout the procedure, ensuring sterile technique is maintained throughout the procedure, carrying out the procedure, and providing the participant with verbal and written after-care procedures. The assistant&#39;s role is to handle and rapidly process the adipose tissue obtained for later analysis and/or storage. The assistant also helps by being the &#34;non-sterile hands&#34; and ensuring the participant is at ease throughout the procedure. The purpose of this video and paper is to describe the step-by-step biopsy procedure to safely obtain subcutaneous adipose tissue from the abdominal area.

human subcutaneous adipose tissue sampling using a mini-liposuction technique

Studies on adipose tissue are useful in understanding metabolic and other conditions. Human subcutaneous adipose tissue is accessible. With appropriate training and strict adherence to aseptic technique, subcutaneous adipose samples can be safely and efficiently obtained in a non-clinical setting by researchers. Following the administration of local anesthetic lateral to the umbilicus, a 14 G needle attached to a 5 or 10 mL syringe is inserted through the skin into the subcutaneous tissue. Under suction, the syringe is moved in a reciprocating, slicing motion to isolate fragments of adipose tissue. Withdrawing the plunger is enough to ensure that adipose tissue fragments are aspirated through the needle into the syringe. A single biopsy can collect about 200 mg of tissue. This biopsy technique is very safe for both participants and research staff. Following the biopsy, participants can resume most everyday activities, although they should avoid swimming and overly strenuous activities for 48 h to avoid excessive bleeding. Participants can safely undergo 2 biopsies within a single day, meaning that the technique can be applied in before-after acute intervention studies.

The described adipose tissue biopsy procedure is an efficient and low-risk technique for researchers to obtain subcutaneous adipose tissue samples from human volunteers. We performed 39 subcutaneous adipose tissue biopsies using the described procedure in 11 healthy, normal weight females (age, 27.4 &#177; 3.3 years; body mass index (BMI), 22.6 &#177; 1.5 kg.m2). All participants attended the laboratory between 07:00 and 10:00 following an 8-12 h fasting period. Sample yield using this adipose tissue biopsy pr...
