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.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA It is rare nowadays that a whole year goes by without a major earthquake event wreaking havoc somewhere around the world. In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...

A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

The Food Chain Energy is one of the most important abiotic factors in an ecosystem and organisms in an ecosystem are connected by the flow of energy and matter among one another. Since energy can be neither created nor destroyed, it can only change form or be transferred to the next organism in a food chain. For example, every time a cow grazes on grass or an osprey hunts and consumes fish, energy is transferred from the consumed organism to the consumer. Each of these interactions in a food...

In this protocol, we describe how to generate murine primary epithelial colon monolayers directly from intestinal crypts. We provide experimental approaches to generate confluent monolayers on permeable filters, confluent monolayers for scratch wound healing and biochemical studies, and sparse and confluent monolayers for immunofluorescence analysis.
FAQs
Homeostasis depends on matching cell production with differentiation, upward displacement, specialized activity, and eventual shedding. Stem and progenitor cells replenish the epithelial population near the crypt base, while their descendants move into positions where they perform distinct functions. Studying this balance shows how tissue renewal remains stable rather than allowing uncontrolled accumulation or depletion of cells.
The stem-cell niche provides the local context that helps preserve stem-cell activity and organize renewal. Its importance becomes clear when examining how cells are generated, maintained, and directed into differentiating descendants. This relationship connects cellular behavior with tissue-level stability and helps explain how intestinal epithelium can sustain ongoing replacement while retaining an organized crypt structure.
Displacement and loss determine where epithelial cells function and how long they remain in the tissue. As descendants move upward, they transition from production near the crypt base toward specialized activity near the villus before shedding. Examining these stages clarifies how position, differentiation, and removal work together to complete the renewal cycle.
This framework allows researchers to ask how changes in proliferation, differentiation, migration, or shedding affect epithelial stability. It can also reveal whether altered behavior begins with stem or progenitor cells, during descendant maturation, or during later displacement and loss. These questions connect individual cell behavior with the overall condition of renewing tissue.
After injury, coordinated renewal processes become relevant to understanding regeneration. Researchers can examine whether stem and progenitor cells continue producing descendants, whether cells maintain their progression toward specialized regions, and how tissue restores epithelial organization. This perspective links the activity of the crypt niche with the broader capacity of intestinal tissue to recover.
These conditions are associated with abnormalities in proliferation and differentiation, two processes that strongly influence epithelial renewal. Studying crypt dynamics provides a way to place such abnormalities within the sequence of cell generation, maturation, displacement, and loss. That context helps distinguish disrupted tissue regulation from the coordinated behavior expected during normal renewal.
