Development of cardiac fibrosis and arrhythmias is controlled by the activity of
and communication between cardiomyocytes and fibroblasts in the heart.
Myocyte-fibroblast interactions occur via both direct and indirect means
including paracrine mediators, extracellular matrix interactions, electrical
modulators, mechanical junctions, and membrane nanotubes. In the diseased heart,
cardiomyocyte and fibroblast ratios and activity, and thus myocyte-fibroblast
interactions, change and are thought to contribute to the course of disease
including development of fibrosis and arrhythmogenic activity. Fibroblasts have a
developing role in modulating cardiomyocyte electrical and hypertrophic activity,
however gaps in knowledge regarding these interactions still exist. Research in
this field has necessitated the development of unique approaches to isolate and
control myocyte-fibroblast interactions. Numerous methods for 2D and 3D
co-culture systems have been developed, while a growing part of this field is in
the use of better tools for in vivo systems including cardiomyocyte and
fibroblast specific Cre mouse lines for cell type specific genetic ablation. This
review will focus on (i) mechanisms of myocyte-fibroblast communication and their
effects on disease features such as cardiac fibrosis and arrhythmias as well as
(ii) methods being used and currently developed in this field.
