In this video, we demonstrate a technique to isolate whole crypts from a mouse’s small intestine. The isolated whole crypts can be used to propagate long-lived and self-renewing 3D organoids in vitro.

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously renew...

This protocol details the derivation of transplantable hematopoietic stem cells from mouse embryonic stem cells (ESC) and their subsequent injection into lethally irradiated recipient mice. Briefly, ESC are differentiated as embryoid bodies, which are then infected with retroviral HoxB4 and co-cultured with OP9 stromal cells and hematopoietic cytokines.

We describe a protocol to isolate murine small intestinal crypts and culture intestinal 3D organoids from the crypts. Additionally, we describe a method to generate organoids from a single intestinal stem cell in the absence of a sub-epithelial cellular niche.
FAQs
These pathways provide opposing or complementary niche inputs that regulate whether crypt base stem cells remain self-renewing and divide. Their combined activity helps control the balance between maintaining the stem-cell pool and generating new epithelial progeny. Studying this signaling environment therefore reveals how local tissue cues govern intestinal homeostasis.
Transit-amplifying progenitors connect stem-cell activity with epithelial replacement. After being produced by crypt base stem cells, they expand the regenerative output and then differentiate into absorptive or secretory epithelial cells. This intermediate stage explains how a relatively localized stem-cell population can continually supply the diverse cell types required to maintain the gut lining.
The surrounding niche does more than support routine self-renewal; its signals help regulate stem-cell division during tissue repair. Comparing activity during steady-state maintenance with activity after injury allows researchers to examine how epithelial regeneration is adjusted to changing tissue demands. This makes niche interactions central to understanding both homeostasis and recovery.
They serve as a model for investigating how intestinal stem-cell behavior can generate organized epithelial tissue in organoid systems. Organoid studies connect the cells’ self-renewal and differentiation programs with questions about tissue formation and maintenance. This application is valuable because it links cellular mechanisms to intestinal epithelial biology.
Because crypt base stem cells regulate epithelial renewal and participate in repair, changes in their behavior can be examined in disease-focused research. Investigators use this system to connect stem cell–niche interactions with inflammatory disease and colorectal cancer biology. The goal is not only to study regeneration, but also how disrupted renewal may relate to pathological states.
They provide a direct framework for studying adult tissue maintenance, regeneration, and communication between stem cells and their niche. Their position within intestinal crypts links local signaling to production of differentiated epithelial cells, while their role in repair extends the model beyond routine turnover. Consequently, they connect cell biology with disease and regenerative research.
