In Vivo Imaging of Bone Marrow Long-Chain Fatty Acid Uptake.

In vivo imaging enables the detection and visualization of many different processes occurring within the body. Fatty acid uptake is a fundamental cellular process which is essential for the use of free fatty acids (FFAs) as a fuel source for metabolism. Detection and visualization of in vivo FFA uptake in the bone marrow has been relatively unknown. Here, we describe the process of non-invasive bioluminescent imaging of in vivo FFA uptake within the bone marrow.
