According to AGA’s Center for Gut Microbiome Research & Education, this critical resource will help advance the utility and reproducibility of microbiome-based diagnostics — “which still remain relatively meaningless clinically, although patients continue to buy direct-to-consumer tests, and a standard reference material will mean there’s a better way to ensure quality control and accuracy.”
Though not a therapeutic, Human Fecal Material RM is expected to speed up gastrointestinal (GI) therapeutics since many microbiome-based drugs are inspired by fecal transplants with human stool as the developmental starting point. A standardized reference material will be an important resource as industry develops and tests new drugs. It can be purchased online at the NIST Store (shop.nist.gov).
The product consists of eight frozen vials of exhaustively studied human feces suspended in aqueous solution. Available are more than 25 pages of data identifying the key microbes and biomolecules in the material. Scientists, including those working at biopharmaceutical and biotech companies, can use this material to further their research and develop new drugs that target the microbiome, including treatments that contain living bacteria.
Development
According to NIST, the stool material is “the most precisely measured, scientifically analyzed, and richly characterized human fecal standard ever produced.
“The project ran for about 6 years from start to finish, the last 2 for manufacturing, characterization, and writing,” said NIST molecular geneticist Scott A. Jackson, PhD, who helped develop the product. “We hope our reference material will lay the foundation for gut microbiome research to thrive and reach its full potential.”
As founder of NIST’s Complex Microbial Systems Group, Jackson is leading international efforts to improve microbiome and metagenomic measurements by organizing inter-lab studies and refining reference materials and methods.
The project collected stool from two cohorts of donors, ie, vegetarians and omnivores, with each cohort comprising four to six donors. Material from each cohort was pooled and homogenized before being aliquoted into 5000 vials per cohort. About 300 tubes from each cohort were picked, and aliquots then underwent multiomic analyses.
Offering his perspective on the new product, Sudhir K. Dutta, MBBS, associate professor in the Division of Gastroenterology and Hepatology at Johns Hopkins University School of Medicine, Baltimore, said, “This tool will be 100% useful for microbiome research.”
And according to Lori Holtz, MD, MSPH, professor of pediatric gastroenterology, hepatology, and nutrition at Washington University School of Medicine in St. Louis, Missouri, the material will aid microbiome research by allowing interpretability and repeatability across studies. “Microbiome research is a relatively new field, and protocols differ from group to group and lab to lab, so it’s been difficult to compare results across studies,” she told GI & Hepatology News. “A standard stool product will allow for greater comparability in preclinical studies and later clinical trials testing interventions to alter the microbiome.”
The NIST developers are looking forward to reaction from the GI research community. “Over the last several years, we’ve released smaller pilot batches of material to smaller groups of stakeholders,” said Jackson. “We’ve used the feedback on these earlier batches to inform the manufacturing and characterization of the final batch that was released in March, but we don’t yet have any feedback yet on the current material.”
Jackson, Dutta, and Holtz disclosed having no relevant competing interests.
