Non-invasive in vivo tissue imaging with functional optical coherence tomography (OCT)

Tissue assessment is important in a variety of different applications, including clinical diagnosis and treatment, pharmaceutical and chemical development, and tissue engineering. The most basic and important parameter assessed is tissue structural information which indicates change on a cellular level. However, structural information alone is not enough to fully understand the tissue physiology.

Researchers from the University of Dundee have developed functional optical coherence tomography (OCT) to enable high quality, ultrafast, qualitative and quantitative characterisation of both tissue structure and function in vivo. The technique has the potential to both reduce and refine animal use, as long-term serial tissue monitoring in small animals is possible, and more invasive tissue assessment is avoided.  There is also the possibility to use OCT on biomimetic tissue models, enabling more information to be generated in these models without destroying the tissue, potentially opening up new opportunities for these non-animal models to replace some in vivo work.

They were seeking partners to apply this technique to their research, particularly in the areas of tissue engineering, diabetes or wound healing. Through CRACK IT Solutions, Professor Huang and her team are now working with Thea Pharmaceuticals and Keele University to explore the potential use of OCT in monitoring corneal wound healing.  Multiple animal models for corneal wound healing are currently used including rodent, rabbit and dog models. These can be extremely painful due to the high density of the nerves in the eye and can result in infections. Thea Pharmaceuticals have recently developed a new drug to promote corneal ulcer healing. OCT will be used to monitor the effect of this drug on tissue repair and regeneration in a human corneal tissue model, providing an excellent example of replacing the use of animal models for assessing drug effects on human tissue analogues.
