Mapping cranial vasculature and adjacent neurovascular interfaces in their entirety will enhance our understanding of central nervous system function in any physiologic state. We present a workflow to visualize in situ murine vasculature and surrounding cranial structures using terminal polymer casting of vessels, iterative sample processing and image acquisition, and automated image registration and processing. While this method does not obtain dynamic imaging due to mouse sacrifice, these studies can be performed before sacrifice and processed with other acquired images. For complete details on the use and execution of this protocol, please refer to Rosenblum et al..

Aetiopathogenesis: Sacral fractures represent an often overlooked interface between spinal and pelvic ring injuries. They typically occur in high-energy trauma or in older patients with osteoporosis.
Diagnostics: Due to their complex anatomy and deep location, they are difficult to detect using conventional radiography; thus, computed tomography (CT) is considered the diagnostic gold standard and allows precise fracture analysis.

While locating in different microenvironments, glioblastoma stem-like cells (GSCs) receive maintenance signals and information to exploit neurovascular tracts. Although the cell adhesion mechanisms to blood vessels have been explored, the mediators guiding GSC interaction with the endothelial cells and their matrix remain incompletely resolved. Here, we identify junctional adhesion molecule C (JAMC) as a key regulator of heterophilic and homophilic interactions of GSC to endothelial surfaces.

The blood-brain barrier (BBB) is a critical central nervous system interface that tightly regulates the exchange of substances between the blood circulation and the brain parenchyma. The BBB, glia, mural cells and neurons form the neurovascular unit (NVU), which modulates cerebral homeostasis. Traditionally considered a uniform and selective barrier, emerging research has unveiled significant heterogeneity in BBB properties across various brain structures.

Background: Neurovascular electronic devices, including brain-computer interfaces (BCIs), offer a minimally invasive approach to diagnosing and treating neurological disorders. Implanting BCIs in superficial cortical veins, owing to their proximity to sensorimotor cortices, may improve motor function restoration. However, marked anatomical variability and the complex anteriorly directed connection with the superior sagittal sinus (SSS) complicate device navigation.

Severe burn injuries pose a critical challenge due to the destruction of neurovascular networks, which are indispensable for skin regeneration and often lead to incomplete healing and functional deficits. This study introduces an organic-inorganic nanocomposite hydrogel that orchestrates neurovascular network reconstruction to achieve full-thickness skin regeneration in burn wounds. Composed of gelatin-based matrices embedding mineralized metal-phenolic nanoparticles (MMF) and stem cell-derived exosomes (EXO), this "dual-engine" system synergizes MMF's ion-releasing (Zn, SiO, tannic acid) and EXO's bioactive signaling to overcome regeneration barriers.
