Vascular mapping of monochorionic (MC) twin placentas after birth provides a means for detailed demonstration of vascular connections between the twins’ circulations. Imbalance of these connections is thought to play a pivotal role in the development of complications of MC twinning including twin-to-twin transfusion syndrome.

We present a method for microfluidic deposition of patterned genipin and fibronectin on PDMS substrates, allowing extended viability of vascular smooth muscle cell-dense tissues. This tissue fabrication method is combined with previous vascular muscular thin film technology to measure vascular contractility over disease-relevant time courses.

Fate Mapping

Fate mapping is a technique used to understand how embryonic cells divide, differentiate, and migrate during development. In classic fate mapping experiments, cells in different areas of an embryo are labeled with a chemical dye and then tracked to determine which tissues or structures they form. Technological improvements now allow for individual cells to be marked and traced throughout embryonic development and adulthood. This video reviews the concepts behind fate mapping, and then details a...

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California One principle of brain organization is the topographic mapping of information. Especially in sensory and motor cortices, adjacent regions of the brain tend to represent information from adjacent parts of the body, resulting in maps of the body expressed on the surface of the brain. The primary sensory and motor maps in the brain surround a prominent sulcus known as the central sulcus. The cortex...
FAQs
Each modality contributes a different signal: Doppler ultrasound detects blood flow, whereas computed tomography angiography and magnetic resonance angiography depict vessels through distinct imaging approaches. Injected contrast media can enhance the vessel lumen when needed. Together, these outputs help clinicians trace vessel location, continuity, and branching architecture before interpreting abnormalities or planning treatment.
A vascular map becomes clinically useful when its anatomy is interpreted alongside vessel condition. It can reveal stenosis, meaning narrowing, occlusion, aneurysms, or malformations, while also showing how affected vessels relate to nearby branches. This combined view supports diagnosis and helps clinicians connect a structural finding with the treatment-planning decisions it may influence.
Branching patterns show how vessels are arranged beyond a single main channel, while collateral circulation identifies alternative pathways for blood flow. Recording both features gives clinicians a more complete picture of individual vascular anatomy. That information can matter when a vessel is narrowed or blocked and when an intervention must account for routes that support surrounding tissues.
A typical workflow selects an appropriate imaging approach, acquires vessel information through Doppler ultrasound, computed tomography angiography, magnetic resonance angiography, or contrast enhancement, and then examines the resulting map. Clinicians assess vessel course, branches, and condition, including stenosis, occlusion, aneurysms, malformations, and collateral circulation, before using the findings for diagnosis or treatment planning.
Preoperative mapping is especially useful when clinicians must plan an access route, position a graft, or design tissue reconstruction around a patient’s individual vessels. By showing the course and branching pattern before intervention, the map helps the surgical team account for relevant anatomy in advance. This can support greater procedural precision and help reduce complications.
The resulting map provides more than a vessel location: it can characterize the arrangement of branches, indicate the presence of stenosis or occlusion, and identify aneurysms, malformations, or collateral circulation. Clinicians use these findings to support diagnosis, select an appropriate treatment approach, and tailor care to the patient’s documented vascular anatomy.
