Preparing Highly Viable Single-Cell Suspensions from Mouse Pancreatic Islets for Single-Cell RNA Sequencing

Area of Science:

• Endocrinology
• Molecular Biology
• Genomics

Background:

• Pancreatic islets contain diverse cell types (alpha, beta, delta, epsilon, PP cells).
• Cellular heterogeneity complicates the interpretation of whole-islet transcriptome data.
• Single-cell transcriptomics is crucial for dissecting cellular heterogeneity and identifying subpopulations.

Purpose of the Study:

• To describe a detailed protocol for mouse pancreatic islet isolation, culturing, and dissociation.
• To provide a method for generating single-cell suspensions suitable for single-cell RNA sequencing.
• To facilitate the investigation of gene expression at the single-cell level within pancreatic islets.

Main Methods:

• Mouse pancreatic islet isolation and culturing.
• Dissociation of islets into a single-cell suspension.
• Library preparation for single-cell RNA sequencing.

Main Results:

• The protocol yields highly viable single cells from mouse pancreatic islets.
• The generated single-cell suspensions are suitable for downstream single-cell RNA sequencing library preparation.
• This method addresses the challenge of interpreting transcriptome data from heterogeneous islet populations.

Conclusions:

• The described protocol is effective for preparing mouse pancreatic islets for single-cell transcriptomic analysis.
• This technique allows for detailed investigation of cellular heterogeneity and gene expression within pancreatic islets.
• The protocol supports advancements in understanding islet cell function and disease.
