The images, 3D reconstructions and digital movies below represent the diverse types of experiments and imaging underway at the MITI core.  In addition to intravital imaging of multiple fluorophores in live small rodents, collagen second harmonic imaging, multiphoton imaging of optically cleared samples, and live cell tracking in fresh tissue explants is actively underway.

Individual eGFp positive neuron s(green) with clearly delineated dendritic spines are observed in close proximity to a TurboRFP positive astrocyte (red) in the cortex of a live mouse using specialized imaging windows.

Specialized imaging windows are used to track long term (weeks to months) changes in GFP positive cancer cells (green) and second harmonic generation from fibrillar collagen fibers (cyan) in live mice after orthotopic implantation of cancer cells.
