オルガノイド研究のためのマウス腸陰窩および単一幹細胞からのオルガノイドの3D培養

Overview

This study investigates the maintenance of homeostasis by intestinal stem cells at the base of murine small intestinal crypts. The authors present a detailed protocol for isolating these crypts and culturing 3D organoids, enhancing our understanding of stem cell behavior in the gastrointestinal tract.

Key Study Components
