Use Of Second Harmonic Generation (Shg) Imaging For 3-Dimensional Ultrastructural Visualization Of Muscle Repair Mechanisms, Matthew Dufner

Honors Scholar Theses

In this study, we have combined SHG imaging with various fluorescent dyes which are designed to stain nuclei and used a skeletal muscle injury and regeneration model to establish the ability of this approach to reliably and reproducibly evaluate the above nuclear parameters. By using the cobra cardiotoxin (CTX-1), which creates acute well defined injuries within the muscle, on the tibialis anterior (TA) and gastrocnemius hind limb muscles of mice, predictable and reproducible regenerative patterns (in response to acute injury) can be observed by harvesting muscle samples at specific time points during recovery. Through SHG imaging, we endeavor to document …
