Abstract
Background
The objective of the COMET (COllection of MEtabolic Tissues) biobank project is to create a
high-quality collection of insulin-sensitive tissues (liver, muscle, adipose tissues, and epiploic artery) and blood sample derivatives (plasma, serum, DNA and RNA), collected from
270 grade 2–3 obese patients undergoing bariatric surgery. Relevant data on patient such
as clinical/biological characteristics and sample handling are also collected. For this, our
aim was to establish a Quality Management System (QMS) to meet the reliability and quality
requirements necessary for its scientific exploitation.

Materials and methods
The COMET QMS includes: (1) Quality Assurance to standardize all stages of the biobanking process, (2) Quality Controls on samples from the first patients included in order to validate the sample management process and ensure reproducible quality; and 3) “in process”
Quality Controls to ensure the reliability of the storage procedures and the stability of the
samples over time.
Results
For serum and plasma, several corrective actions, such as temperature handling and centrifugation conditions, were made to the protocol and led to improvement of the volume and
quality of samples. Regarding DNA, all samples evaluated achieved a satisfactory level of
purity and integrity and most of them yielded the required DNA quantity. All frozen tissue
samples had RNAs of good purity. RNA quality was confirmed by RIN, achieving values in

most cases over 7 and efficient amplification of housekeeping genes by RT-qPCR, with no
significant differences among samples from the same tissue type. In the “in process” Quality
Controls, DNA, RNA, and histological integrity of tissues showed no differences among
samples after different preservation times.
Conclusion
Quality Control results have made it possible to validate the entire biobank process and confirm the utility of implementing QMS to guarantee the quality of a biospecimen collection.
Introduction
The development of human tissue biobanks is now considered as an indispensable tool for the
progression of biomedical research and the development of new therapeutic strategies in personalized medicine (population stratification, biomarker discovery,. . .) [1]. At present, one of the
challenges of human biospecimen biobanks is to provide quality-assured materials as well as accurate and reliable associated data (biospecimen are defined as tissues or blood derivatives removed
from the patient). There is a recognized need to develop more standardized and harmonized technical procedures for the constitution of biobanks, especially in terms of biospecimen collection
and associated data. In this context, the purpose of the COMET (COllection of MEtabolic Tissues)
biobank project [2] is to create a high-quality collection of insulin-sensitive tissues (liver, muscle,
adipose tissues and epiploic artery) and blood derivatives (DNA, RNA, plasma and serum) collected from grade 2–3 obese patients (body mass index [BMI] � 35 kg/m2) undergoing bariatric
surgery. The overarching goal of this biobank is to promote translational and pharmaceutical
research in the field of type 2 diabetes (T2D) and related metabolic disorders.
Multiple preanalytical factors can affect the integrity of human biospecimens and may thus
impact downstream molecular applications. Surgical resection methods, duration and conditions of transport, time and temperature prior to snap-freezing can lead to metabolic, biochemical, and physical stresses known as warm ischemia [3]MA. These factors can also impact
the long-term integrity of samples after several years of storage in the biobank (samples are
defined as aliquots of tissues or blood derivatives stored in the biobank). Therefore, the quality
of human samples and the traceability of sample-related information must be efficiently standardized by the creation of specific procedures to be applied during the biobanking [4].
In order to achieve this, the COMET biobank constitution process was standardized using
a Quality Management System (QMS), with two components: Quality Assurance and Quality
Controls. The QMS included quality controls of samples at microscopic, macroscopic and
molecular levels and validation of the sample management process on the first patients
included in the clinical trial. Quality con (...truncated)
