This video demonstrates a quantification technique for CO2 released during substrate oxidation using 14C-radiolabeled substrates. The released 14CO2 is trapped in an alkaline solution and quantified by a scintillation counter. The oxidation of different substrates varies between tissues and reflects the pathophysiological condition of the tissue.

CRISPR/Cas systems mediate adaptive immunity in Bacteria and Archaea. Many Cas proteins are proposed to act as endoribonucleases acting on crRNA precursors of varying length. Here we illustrate three different approaches to generate pre-crRNA substrates for the biochemical analysis of Cas endonuclease activity.

Self-assembled monolayers (SAMs) formed from long chain alkane thiols on gold provide well-defined substrates for the formation of protein patterns and cell confinement. Microcontact printing of hexadecanethiol using a polydimethylsiloxane (PDMS) stamp followed by backfilling with a glycol-terminated alkane thiol monomer produces a pattern where protein and cells adsorb only to the stamped hexadecanethiol region.
FAQs
Contact guidance directs cells to respond preferentially to the groove orientation. As cells encounter the parallel topography, they can reorganize their cytoskeleton and focal adhesions along that direction. This spatial organization changes how cells spread, move, and align, allowing researchers to connect surface geometry with observable cellular behavior.
The cytoskeleton provides an internal structural framework that reorganizes in response to the grooves, while focal adhesions help connect the cell to the substrate. Their coordinated orientation supports directional spreading and alignment. Examining these changes helps explain how physical cues at a surface are translated into cellular organization and movement.
A Microgrooved Substrate supports analysis of several related responses, including adhesion, spreading, migration, and alignment. These behaviors can be considered together to determine how cells adapt to an organized physical environment. The approach is especially useful when researchers need to observe geometry-dependent changes under controlled culture conditions.
Their engineered, parallel topography provides a reproducible physical cue rather than an uncontrolled environmental feature. Researchers can therefore examine how geometry regulates cell behavior in a defined culture system. This controlled setting helps relate changes in adhesion, spreading, migration, or alignment to the structural organization presented by the surface.
Cells are cultured on the engineered surface, and their responses are examined in relation to the groove direction. Researchers can assess whether cells adhere, spread, migrate, or align according to the imposed topography. This workflow creates a controlled model for investigating how physical structure influences cellular organization without relying only on native tissue observations.
These substrates can model structural cues relevant to tissue organization, wound repair, and neuronal growth. They allow researchers to investigate how cells organize and move when exposed to a consistent directional surface feature. The same controlled approach also contributes to biomaterial design by testing how engineered geometry may influence cellular responses.
Microgrooved surfaces provide a reproducible way to study cellular responses to structural features that cells may encounter in native tissues. Findings about alignment, migration, adhesion, and spreading can inform the design of materials intended to support organized cell behavior. They also help connect engineered culture models with broader questions of tissue structure and repair.
