Described here is a simple workflow to differentiate endothelial cells from human pluripotent stem cells followed by a detailed protocol for their mechanical stimulation. This allows for the study of the developmental mechanobiology of endothelial cells. This approach is compatible with downstream assays of live cells collected from the culture chip after mechanical stimulation.

Introduction to Organ-on-Chip Models Organ-on-chip models are advanced microphysiological systems that recreate key structural and functional features of human organs in a controlled laboratory setting. These devices integrate living human cells within microfluidic channels, allowing researchers to simulate tissue–tissue interfaces, fluid flow, and mechanical forces that are essential for normal organ function. Unlike traditional cell cultures, which often lack these dynamic physiological cues,...

Chip-Based Digital PCR to Detect Rare Transcript Variants Using a Nanofluidic Chip

2025
This video demonstrates chip-based digital PCR — a variation of the digital PCR technique that is useful in detecting rare transcript variants. The PCR reaction is partitioned into the chambers of a nanofluidic chip, each of which acts as an independent reaction. The detection of fluorescence signals from the chambers with amplified targets confirms the presence of rare transcript variants in the sample.
FAQs
Fluid flow through perfused channels generates shear stress at the endothelial cell surface. These mechanical forces can influence vessel formation and remodeling, while the controlled channel environment lets investigators examine responses outside the embryo. This makes flow a tunable experimental variable for studying how physical conditions shape developing vasculature.
Developing vessels respond to more than fluid forces. Cellular interactions and molecular signals work alongside mechanical cues to shape vascular development. A fetal vessel on-chip provides a controlled setting for examining these influences together, helping researchers separate interacting developmental factors that are difficult to investigate directly within living embryonic or placental tissues.
The model can support investigation of vessel remodeling and barrier function in addition to vessel formation. Remodeling addresses how vascular structures change over time, whereas barrier studies focus on how effectively the vessel interface functions. Considering these processes together helps connect structural development with the functional properties of fetal vasculature.
A typical setup combines endothelial cells with small microfluidic channels that can be perfused under controlled conditions. The channel geometry supplies a defined environment, and fluid movement introduces shear stress. Together, these components allow investigators to study developing vessel behavior while controlling the laboratory context more precisely than in many tissue-based observations.
In developmental biology, the platform helps researchers examine how mechanical forces, cellular interactions, and molecular signals shape fetal vasculature. It is especially useful when direct investigation in embryos or placental tissue is difficult. By recreating selected developmental features in the laboratory, the system supports focused studies of vascular formation and function.
Fetal vessel on-chip systems can support studies of placental and embryonic vascular disorders, as well as responses to drugs. Researchers can observe how developing vessel structures and barrier-related functions respond under controlled conditions. This provides a laboratory approach for investigating developmental mechanisms and treatment effects without relying exclusively on direct studies in living tissues.
