Overview
The mission of the Light Imaging Section is to give NIAMS scientists access to state-of-the-art light imaging equipment and to offer training and assistance at all stages of the acquisition and analysis of images with various techniques of light microscopy.
Our research focuses on the use of light microscopy techniques to elucidate poorly understood aspects of skeletal muscle cell biology, i.e. the organization of microtubules and their associated subcellular organelles, particularly the Golgi complex. We also strive to apply new modalities of light microscopy to the quantitative analysis of skeletal muscle pathologies.
