**Preface to "Stem Cell Research on Cardiology"**

At present, stem cell research in cardiology ranges from fundamental research over translational preclinical experiments up to promising clinical trials, to investigate a putative new medicinal product. The aim of all these efforts is to improve treatment opportunities for cardiac patients and to prevent severe disease courses.

In this context, new technologies are constantly emerging, and offer new impressive possibilities to analyze data and to generate testing capacities suitable for clinical application.

This Special Issue of Cells comprises highly relevant original articles and brief communications, as well as informative reviews analyzing the current situation of cardiac stem cell research. Here, also new elementary aspects of several myocardial diseases and cardiac remodeling, with respect to physiological and pathological events, e.g. arrhythmia and inflammation, are lit up. Furthermore, programming approaches, maturation strategies and the characterization of cardiac cells for translational research are addressed, and the reader will be informed about prospective approaches in 3D cell aggregate application in the field.

We expect this collection of articles to provide valuable input for future research and further discussions in the wide field of cardiac regenerative medicine.

We sincerely wish to thank all authors who have contributed to this Special Issue.
