About This Webinar
Nonlinear optical imaging techniques permit visualization and quantification of both microstructural and functional features of biological samples with high spatial resolutions, deeper light penetration, and lower phototoxicity. Realizing the potential of these techniques in pharmacological studies, we designed and developed a multiphoton imaging platform at the GSK Center for Optical Molecular Imaging (COMI) lab at the University of Illinois Urbana-Champaign. In a preclinical study conducted at the COMI lab, the multimodal imaging platform was used to longitudinally monitor angiogenesis, metabolic changes, and collagen remodeling during the wound healing process in a noninvasive, label-free manner.
Mice were separated into four groups: control, placebo, low-concentration (LC), and high-concentration (HC) treatment. A statistically significant improvement in the functional relationship between angiogenesis, metabolism, and structural integrity was observed in the HC group. In a clinical study, multimodal optical imaging methods were utilized to assess and quantify skin changes associated with psoriasis, and quantitative endpoints were correlated with disease progression. Alex discusses how these studies demonstrated the promising potential of multimodal multiphoton imaging techniques to aid in disease characterization, drug development, and treatment evaluation.
