Preservation of laboratory samples, specimens, and reagents using extreme cold is routinely performed in biomedical research labs. This video will discuss some of the methods for keeping laboratory samples cold and will explain the correct cooling method to use for each experimental requirement. For example, cooling agents, such as ice and dry ice, are typically used when keeping samples cold during experiments. This video discusses the physical properties of the most commonly used cooling...

Perfusion decellularization is a novel technique to produce whole liver scaffolds that retains the organ's extracellular matrix composition and microarchitecture. Herein, the method of preparing whole organ scaffolds using perfusion decellularization and subsequent repopulation with hepatocytes is described. Functional and transplantable liver grafts can be generated using this technique.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA One of the more insidious types of failures that can occur in structures are brittle fractures,which are mostly due to either poor quality materials or poor material selection. Brittle fractures tend to occur suddenly and without much material inelasticity; think of a bone fracture, for example. These failures often occur in situations where there is little ability for the material to develop...

FAQs
Chilled processing matters because it slows enzymatic degradation during lysis and washing. That reduced activity can help limit damage to extracellular-matrix proteins, which provide structural support and tissue-specific biochemical cues. The temperature condition therefore is not merely a handling preference: it is used to balance effective cellular-component removal against preservation of scaffold features needed for later bioengineering applications.
Detergents, enzymes, and osmotic treatments can serve as supporting agents during cellular removal, but the overview does not assign them identical functions or prescribe one universal combination. Their inclusion should therefore be understood as part of a controlled lysis and washing strategy. The central design concern is achieving sufficient removal while avoiding unnecessary loss of matrix proteins, architecture, or biochemical information.
Cold Temperature Decellularization is especially valuable when preservation of tissue-specific structure matters. Chilled lysis and washing can limit matrix damage while the process removes cells and cellular components, allowing the resulting scaffold to retain aspects of its original architecture and biochemical cues. Those retained features can influence how the material is considered for regenerative medicine, disease modeling, or cell reseeding.
A basic workflow begins with lysis and washing under chilled conditions, using detergents, enzymes, osmotic treatments, or combinations of these approaches to assist removal. Processing is followed by recovery of the acellular scaffold, whose matrix preservation can then be considered for downstream use. The key procedural relationship is that each removal step must support decellularization without compromising the extracellular matrix.
The resulting material can be evaluated conceptually by asking whether cellular components were removed and whether tissue-specific architecture, matrix proteins, and biochemical cues were preserved. These features determine whether the scaffold offers a useful structural and biochemical environment. A preserved acellular matrix can also provide a platform for reseeding with cells, connecting processing outcomes to later tissue-engineering studies.
In bioengineering, this approach supports several research directions rather than a single end use. Acellular scaffolds may contribute to biomaterial development for regenerative medicine, provide tissue-relevant substrates for disease modeling, and inform transplantation research. Because the matrix can retain structural and biochemical information from the source tissue, the method also supports studies that involve subsequent cell reseeding.
