Analysis of rodent cerebrovascular anatomy plays an important role in experimental stroke research. In this context, intravascular perfusion with colored latex has been considered as a standard tool for several years. However, this technique implies distinct technical limitations, which undermine its reproducibility. Here, we describe a simple method to visualize cerebral vessels in a reproducible manner. Injection of a mixture of two commercially available carbon black inks through the left...

Formulation of stable, functional inks is critical to expanding the applications of additive manufacturing. In turn, knowledge of the mechanisms of dispersant/particle bonding is required for effective ink formulation. Diffuse Reflectance Fourier Transform Infrared Spectroscopy (DRIFTS) is presented as a simple, inexpensive way to gain insight into these mechanisms.

This video describes an antegrade perfusion technique of an isolated mouse heart during which a perfusate is injected through the left ventricle, and eventually, it perfuses the entire myocardium. This method can be used to isolate cardiomyocytes from murine models and generate decellularized hearts for further downstream applications.
FAQs
Patent vessels determine whether the ink can enter and travel through a vascular pathway. When circulation carries the pigment through an open vessel, the ink fills its lumen and outlines that segment for later observation. Vessels that are not patent will not be represented in the same way, so the resulting image reflects accessible vascular connections rather than every possible structural feature.
The method makes branching patterns and vessel connections more visually distinct within prepared tissue. This supports examination of vascular architecture, including how vessels are organized and linked across a tissue region. Because the labeled network can be observed and analyzed, investigators can compare structural differences between samples rather than relying only on less visibly defined tissue anatomy.
Pigmented ink provides a visible contrast inside vessel lumens after it has been transported through the circulation. That contrast outlines the course of accessible vessels and makes their branching arrangement easier to distinguish in prepared tissue. The resulting label is especially useful when the research goal is to relate vessel organization to broader tissue architecture or perfusion patterns.
A basic workflow introduces India ink into the circulatory system, allows it to move through patent vessels, and then prepares the tissue for observation. The ink-filled lumens expose the vascular pattern for visualization and analysis. This sequence links delivery through the circulation with the later assessment of vessel branching, connectivity, and tissue-level organization.
Bioengineers can use the technique when they need to examine vascular development or connections between vessels and an engineered construct. The labeled network provides structural evidence that helps relate tissue architecture to perfusion. It can therefore support evaluation of whether a tissue-engineering strategy or biomaterial is associated with organized vascular formation within the studied sample.
By outlining vessel networks in prepared tissues, the method allows investigators to compare branching patterns, vessel connections, and overall organization between normal and abnormal samples. These comparisons can reveal differences in vascular architecture or perfusion-related structure. In bioengineering studies, the same approach can help assess how materials and tissue-engineering strategies influence the development of functional vasculature.
