iCell® Skeletal Myoblasts: A Model for Interrogating and Modulating Glucose Uptake

Skeletal muscle plays a pivotal role in modulating circulating glucose levels, and the impact of muscle dysfunction on the onset, pathology, and treatment of type 2 diabetes is the subject of intense basic and applied research.

CDI’s iCell® Skeletal Myoblasts provide an excellent model for investigating the etiology, pathology, and potential treatments of type 2 diabetes while Promega's Ultra-Glo Recombinant Luciferase based detection reagents offer easy-to-use, highly sensitive, and robust detection reagents for a variety of cellular processes.  In culture, iCell Skeletal Myoblasts fuse to form myotubes (Figure 1) that exhibit an approximately 2-fold increase in insulin-dependent glucose uptake as well as insulin-independent glucose uptake (Figure 2), and appropriate downstream phosphorylation events (Figure 3).  The recapitulation of native human glucose uptake mechanisms and simple handling of iCell Skeletal Myoblasts along with the non-radioactive robust detection and quantification of the Ultra-Glo reagents make this an ideal preparation for model development and screening in diabetes drug discovery efforts.
