Journal ArticleDOI
Indigenous Bacteria from the Gut Microbiota Regulate Host Serotonin Biosynthesis
Jessica M. Yano,Kristie B. Yu,Gregory P. Donaldson,Gauri G. Shastri,Phoebe Ann,Liang Ma,Cathryn R. Nagler,Rustem F. Ismagilov,Sarkis K. Mazmanian,Elaine Y. Hsiao +9 more
TL;DR: It is demonstrated that Indigenous spore-forming bacteria from the mouse and human microbiota promote 5-HT biosynthesis from colonic enterochromaffin cells (ECs), which supply 5- HT to the mucosa, lumen, and circulating platelets and elevating luminal concentrations of particular microbial metabolites increases colonic and blood5-HT in germ-free mice.
Journal ArticleDOI
Gene-targeted microfluidic cultivation validated by isolation of a gut bacterium listed in Human Microbiome Project's Most Wanted taxa
Liang Ma,Jungwoo Kim,Roland Hatzenpichler,Mikhail A. Karymov,Nathaniel Hubert,Ira M. Hanan,Eugene B. Chang,Rustem F. Ismagilov +7 more
TL;DR: Isolate microfluidicus 1 is, to the authors' knowledge, the first successful example of targeted cultivation of a microorganism from the high-priority group of the Human Microbiome Project’s “Most Wanted” list, and the first cultured representative of a previously unidentified genus of the Ruminococcaceae family.
Journal ArticleDOI
Individually addressable arrays of replica microbial cultures enabled by splitting SlipChips
TL;DR: The design, fabrication, biological validation, and underlying physics of a microfluidic SlipChip device that addresses the challenge of isolation of a novel microbial taxon and provides a facile way to cultivate anaerobes from complex communities.
Journal ArticleDOI
Multistep SlipChip for the Generation of Serial Dilution Nanoliter Arrays and Hepatitis B Viral Load Quantification by Digital Loop Mediated Isothermal Amplification
Mengchao Yu,Xiaoying Chen,Haijun Qu,Liang Ma,Lei Xu,Weiyuan Lv,Hua Wang,Rustem F. Ismagilov,Min Li,Min Li,Feng Shen +10 more
TL;DR: A multistep SlipChip microfluidic device is presented for generatingserial dilution nanoliter arrays in high throughput with a series of simple sliding motions and an eight-step serial dilution SlipChip with a dilution ratio of 1:4 is applied for digital loop-mediated isothermal amplification across a large dynamic range and tested for hepatitis B viral load quantification with clinical samples.
Journal ArticleDOI
One cell at a time: droplet-based microbial cultivation, screening and sequencing
TL;DR: This review aims to provide an overview of droplet microfluidics techniques for microbial research, from high-throughput single-cell cultivation, screening to the targeted or whole-genome sequencing of single cells.
