The purpose of the Specimen Orientation Tag (SpOT) is to function as an orientation tool to aid in individual tissue identification in multi-tissue paraffin blocks. These protocols demonstrate how it is constructed easily from common, low-cost histology materials and serves as a reliable visual marker in paraffin blocks and sections.

This video demonstrates a controlled environment approach to study degradation of lignocellulosic plant tissues by aerobic fungi. The ability to control nutrient sources and moisture is a key advantage of agar-block microcosms, but the approach often yields mixed success. We address critical pitfalls to yield reproducible, low-variability results.

Explant Culture of Neural Tissue

The intricate structure of the vertebrate nervous system arises from a complex series of events involving cell differentiation, cell migration, and changes in cell morphology. Studying these processes is essential to our understanding of nervous system function as well as our ability to diagnose and treat disorders that result from abnormal development. However, neural tissues are relatively inaccessible for experimental manipulations, especially in embryonic mammals. As a result, many...

Histotypic Tissue Culture

Although two-dimensional tissue culture has been common for some time, cells behave more realistically in a three-dimensional culture, and more closely mimics native tissue. This video introduces histotypic tissue culture, where the growth and propagation of one cell line is done in an engineered three-dimensional matrix to reach high cell density. Here, we show the harvesting of cells from donor tissue, followed by cell culture on an engineered construct.
FAQs
Nutrients and oxygen reach cells primarily by diffusion from the surrounding sterile nutrient medium. This makes the regulated environment important: temperature, gas conditions, and pH must support continued tissue function without disrupting the interactions preserved inside the block. The resulting outcome depends on maintaining conditions that allow cells to remain viable within their structural context during ex vivo study.
Keeping cells within an intact tissue piece preserves relationships among multiple cell types and the extracellular matrix. These structural and cellular interactions can influence tissue function and disease-related changes in ways that isolated cells no longer reflect. Consequently, tissue block culture can provide biologically relevant evidence when researchers need to examine responses in a more native organization.
The extracellular matrix and neighboring cells remain part of the experimental material rather than being removed before observation. Their continued presence helps maintain the tissue’s native structural context, allowing researchers to study changes across interacting components instead of focusing on one cell population alone. This is particularly relevant when investigating tissue function, disease-related changes, or repair processes.
The basic workflow places a small, intact tissue piece in sterile nutrient medium and maintains it under regulated temperature, gas, and pH conditions. These controls create the ex vivo environment needed for diffusion of nutrients and oxygen into the tissue. Maintaining sterility and stable culture conditions is therefore central to obtaining interpretable observations from the preserved tissue block.
In medical research, this approach can support studies of tissue function, disease-related changes, wound healing, and responses to drugs or other treatments. Its value is greatest when investigators need tissue-level evidence that retains interactions among cell types and the extracellular matrix. Such findings can also contribute to therapeutic development by testing biological responses in a preserved tissue context.
Tissue block culture can reveal how an intact tissue responds to a drug or other treatment while its cellular organization and extracellular matrix remain present. This produces evidence that is more biologically relevant than observations from isolated cells alone when tissue architecture affects the response. Researchers can use those results to study treatment effects and inform therapeutic development.
