Understanding the cellular and molecular mechanisms of re-endothelialization following arterial denudation injury is of paramount importance in preventing thrombosis and restenosis of arteries. Here we describe a protocol for reproducible arterial denudation injury of the infrarenal abdominal aorta. The procedure was developed to investigate the underlying mechanisms that regulate endothelial regeneration using mouse models.

Capillaroscopy is a non-invasive, efficient, relatively inexpensive and easy-to-learn methodology for directly visualizing capillaries in the microcirculation. However, only one publication to date describes the reliability of a complex software program available for quantitating capillaroscopy data. Here, we present a simple, reliable protocol for quantitating capillaries using a standardized algorithm.

2012
In this report we describe a method to crush mouse sciatic nerve. This method uses readily available hemostatic forceps and easily and reproducibly produces complete sciatic nerve crush. In addition, we describe a method to prepare muscle whole mounts suitable for analysis of nerve regeneration after sciatic nerve crush.
FAQs
These details establish which chemical inputs enter an experiment. Reagents with different identities or purity can change the observed outcome, while an undocumented substitution makes a repeat difficult to interpret. Recording identity and purity lets investigators distinguish variation in chemical behavior from variation introduced by materials. This practice supports meaningful comparison among repeated experiments.
Concentrations, reaction conditions, sample preparation, and instrument settings can each influence the measured result. If any of these variables remains unspecified, another researcher may follow the general method yet produce a different outcome. Reporting them together creates a more complete experimental record and helps identify whether discrepancies arise from chemical conditions, measurement settings, or preparation choices.
Replicated measurements show whether an observed result remains consistent rather than occurring in a single measurement. Appropriate controls provide a comparison that helps reveal effects unrelated to the intended chemical process. Used together, they help separate robust chemical behavior from contamination, experimental variability, or other influences, increasing confidence that the reported finding reflects the system under study.
Standardized protocols reduce variation in how an experiment is performed, while transparent data-processing steps show how raw observations become reported results. Documenting both parts makes undocumented analytical decisions easier to detect and allows others to repeat the workflow more faithfully. The resulting record supports direct comparison of outcomes and helps explain differences between an original experiment and its repetition.
Reproducibility becomes especially important when a chemical method must be validated or transferred beyond its initial experiment. Consistent results provide evidence that the method is dependable, while documented materials, conditions, instruments, and analysis identify what must remain controlled. This information supports decisions about whether a procedure can be compared across experiments or used as a basis for scale-up.
In analytical chemistry, it helps others compare measurements produced with documented preparation and instrument settings. In synthetic chemistry, recorded reagents, purity, concentrations, and reaction conditions clarify whether a product or outcome can be obtained again. For materials chemistry, transparent procedures and analysis help connect reported properties with the methods that produced them, supporting reliable progress across these areas.
