This figure shows the localization of alpha-actinin in a live cardiac myocyte. Chicken cardiac myocytes were obtained from 7-day-old embryos and were transfected with an expression vector encoding GFP-alpha-actinin. The dynamics of GFP-alpha-actinin was monitored by fluorescence microscopy, allowing for the visualization of myofibrillogenesis in the living muscle cell. The GFP-alpha-actinin incorporates into "Z-bodies" which apparently fuse to become the Z-bands of mature myofibrils.
