What is the Benchmark Tool for Cystic Fibrosis Ion Transport Research?
For more than half a century, the Ussing Chamber has been a cornerstone in epithelial physiology research. When it comes to understanding cystic fibrosis (CF) at the cellular level, this system remains the most reliable and precise method for directly measuring CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) function.
At Physiologic Instruments, we’ve refined and optimized Ussing Chamber designs to meet the demanding needs of modern CF research — from basic science to preclinical drug development and personalized medicine.
Why Ussing Chambers Matter in Cystic Fibrosis Research
Cystic fibrosis is caused by mutations in the CFTR gene, which impair chloride and bicarbonate ion transport across epithelial cells. This defect leads to thick, sticky mucus in the lungs, intestines, and other organs, driving the serious complications of the disease.
The Ussing Chamber provides a controlled, reproducible environment to:
-
Mount live epithelial tissue or cultured monolayers.
-
Simulate mucosal and serosal environments.
-
Measure short-circuit current (Isc) and transepithelial resistance (TER) to assess ion transport directly.
By isolating epithelial function from systemic influences, Ussing Chambers give researchers pure, quantitative insight into CFTR activity.
Key Applications in CF Research
1. Drug Discovery & Development
Modern CF therapies, such as CFTR modulators, are designed to improve or restore chloride channel function. Using a Physiologic Instruments Ussing Chamber, researchers can:
-
Establish baseline ion transport in CF patient-derived tissue.
-
Apply potential drug candidates.
-
Quantify improvement in CFTR-mediated currents.
This approach confirms if a therapy is working before moving to costly and time-consuming clinical trials.
2. Personalized Medicine
Patient-derived intestinal organoids and airway epithelial cultures can be tested in Ussing Chambers to determine:
-
Which drug combination best restores CFTR activity for an individual.
-
The optimal dosage for maximum therapeutic effect.
This makes it possible to match the right drug to the right patient, improving treatment outcomes.
3. Studying Disease Mechanisms
Beyond testing drugs, Ussing Chambers allow detailed study of:
-
How inflammation alters CFTR activity.
-
The effects of chronic infection on ion transport.
-
How mucus thickness impacts epithelial function.
