Establishment and Characterization of Patient-derived Gastric Organoids from Biopsies of Benign Gastric Body and Antral Epithelium08:45

Establishment and Characterization of Patient-derived Gastric Organoids from Biopsies of Benign Gastric Body and Antral Epithelium

Gastric patient-derived organoids find increasing use in research, yet formal protocols for generating human gastric organoids from single-cell digests with standardized seeding density are lacking. This protocol presents a detailed method for reliably creating gastric organoids from biopsy tissue obtained during upper...

Detection of G Protein-coupled Receptor Expression in Mouse Vagal Afferent Neurons using Multiplex In Situ Hybridization08:16

Detection of G Protein-coupled Receptor Expression in Mouse Vagal Afferent Neurons using Multiplex In Situ Hybridization

Multiplex in situ hybridization (ISH) was employed to simultaneously visualize the transcripts for two G protein-coupled receptors and one transcription factor in the entire vagal ganglionic complex of the adult mouse. This protocol could be used to generate accurate maps of the transcriptional profiles of vagal afferent...

One-anastomosis Gastric Bypass (OAGB) in Rats08:16

One-anastomosis Gastric Bypass (OAGB) in Rats

This protocol is for the performance of one-anastomosis gastric bypass (OAGB) on rat. The operator performs a long and tubular-stapled gastric pouch followed by hand-sewn anastomosis. For this model, the operator reproduces the same ratio between biliopancreatic and common limb in humans; therefore, the biliopancreatic limb measures 35 cm.

Roux-en-Y Gastric Bypass Operation in Rats

Numerous studies using gastric bypass rat models have been recently conducted to uncover the underlying physiological mechanisms of Roux-en-Y gastric bypass operations. This article aims to demonstrate and discuss the technical and experimental details of our published gastric bypass rat model to understand advantages and limitations of this experimental...
