Fibrosis is the thickening, scarring, or formation of excess connective tissue as a mechanism to repair tissue damage as a result of overuse or injury. Improved imaging techniques assist physicians in effectively treating fibrotic tissues, which occurs in multiple areas of the body.

Second Harmonic Generation is recognized as the ideal non-destructive optical technique to image collagen I and III in biological tissues. Recent technology and instrumentation breakthrough are making this technology more affordable, and compatible with mid-throughput screening. Tissue-specific and validated image analysis, segmentation and quantification software tools based on ‘machine-learning” algorithm are capable of generating robust and operator-independent quantitative fibrosis outcomes, ranging from collagen fiber morphometries to collagen area densities.

In cooperation with HistoIndex (Singapore), Genesis Imaging Labs (Princeton, NJ) has developed a unique imaging and quantification protocols for pre-clinical or clinical trials for the liver, lung, and kidney. See Publications Here

In this webinar, Dr. Li Chen and Dr. Mathieu Petitjean will be showcasing their new results/data on the application of Second Harmonic Generation to image and quantify fibrosis in the Kidney. In their study, they are using methods and Imaging outcomes (vs standard methods) to compare efficacy of Pirfenidone on a interstitial Fibrosis Model (UUO). 

Dr. Petitjean will briefly introduce the instrumentation and the biophysical aspects of SHG coupled to TPEF for non-destructive tissue imaging, as well as the fundamental concepts used in the development of tissue-specific image analysis and quantification for fibrosis.

Dr. Chen will illustrate how the method is applied for kidney fibrosis quantification and anti-fibrotic compound development in a pre-clinical set up, or fibrotic patient study and stratification (in comparison to Metavir scores for instance).
