Coexpression of Intermediate Filament Proteins in the Chick Embryo Heart

摘要

We studied the distribution of intermediate filament proteins during several stages of chick embryo heart development by indirect immunofluorescence and fluorescence-activated cell surface analysis. Vimentin is the predominant intermediate filament during the early stages of cardiac genesis, while desmin appears essentially with maturation. Desmin is the main subunit protein of intermediate filaments in the mature myocyte.
