[EN] The present invention relates to the use of a PTK inhibitor for inducing the differentiation of mesenchymal stem cells into cardiogenic cells, and to a pharmaceutical composition for treating cardiac diseases, which includes cardiogenic cells, the differentiation from mesenchymal stem cells of which was induced by the PTK inhibitor. The transplantation of mesenchymal stem cells to the heart provides immunological and functional improvements, but does not provide electrical stability. However, the mesenchymal stem cells treated with PTK inhibitors are induced to be differentiated into cardiogenic cells to provide electrical stability as the electromechanical integration with host heart tissue is improved, and it is thus possible to effectively treat cardiac diseases such as cardiac infarction, cardiac insufficiency, and arrhythmia. [FR] La présente invention concerne l'utilisation d'un inhibiteur de PTK pour induire la différenciation de cellules souches mésenchymateuses en cellules cardiogéniques et une composition pharmaceutique destinée au traitement de maladies cardiaques, qui comprend des cellules cardiogéniques, dont la différenciation à partir de cellules mésenchymateuses a été induite par l'inhibiteur de PTK. La transplantation de cellules souches mésenchymateuses dans le coeur permet des améliorations immunologiques et fonctionnelles, mais ne confère pas de stabilité électrique. En revanche, les cellules souches mésenchymateuses traitées par des inhibiteurs de PTK sont induites à se différencier en cellules cardiogéniques en conférant une stabilité électrique car l'intégration électromécanique avec le tissu cardiaque hôte est améliorée, et il est donc possible de traiter efficacement des maladies cardiaques comme l'infarctus du myocarde, l'insuffisance cardiaque et l'arythmie.
