Quantitative intrinsic auto-cathodoluminescence can resolve spectral signatures of tissue-isolated collagen extracellular matrix

Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, Elif Vardar, Marcin Stefan Zielinski, Ganesh Vythilingam

By analyzing isolated collagen gel samples, we demonstrated in situ detection of spectrally deconvoluted auto-cathodoluminescence signatures of specific molecular content with precise spatial localization over a maximum field of view of 300 mu m. Correlati ...

A bioactive injectable bulking material; a potential therapeutic approach for stress urinary incontinence

Matthias Lütolf, Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, Elif Vardar, Kalitha Pinnagoda, Ganesh Vythilingam

Stress urinary incontinence (SUI) is a life changing condition, affecting 20 million women worldwide. In this study, we developed a bioactive, injectable bulking agent that consists of Permacol (TM) (Medtronic, Switzerland) and recombinant insulin like gro ...

Fiber density of collagen grafts impacts rabbit urethral regeneration

Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, Elif Vardar, Kalitha Pinnagoda, Ganesh Vythilingam

There is a need for efficient and “off-the-shelf” grafts in urethral reconstructive surgery. Currently available surgical techniques require harvesting of grafts from autologous sites, with increased risk of surgical complications and added patient discomf ...

Engineered acellular collagen scaffold for endogenous cell guidance, a novel approach in urethral regeneration

Jeffrey Alan Hubbell, Peter Frey, Hans Mattias Larsson, Elif Vardar, Kalitha Pinnagoda, Ganesh Vythilingam

The treatment of congenital malformations or injuries of the urethra using existing autologous tissues can be associated with post-operative complications. Using rat-tail collagen, we have engineered an acellular high-density collagen tube. These tubes wer ...
