제목 Enhanced Expression of Growth Factors and Gap Junction Protein by Reduced Graphene Oxide for Myocardial Infarction
초록 Myocardial infarction (MI) is one of the major cardiovascular diseases which causes death around the world. The loss of cardiac cells, which express gap junction proteins, and cardiac fibrosis in myocardial infarction lead to arrhythmia. Mesenchymal stem cell (MSC) implantation has been emerging strategy for cardiac repair after MI. Herein, we report reduced graphene oxide (RGO) which shows high affinity to extracellular matrix (ECM) proteins and high electrical conductivity. We hypothesized that incorporated RGO into MSC spheroid would improve the therapeutic efficacy for MI via the secretion of reparative paracrine factors and the upregulation of gap junction proteins. RGO could not only promote paracrine factors secretion and gap junction crosstalk, but also could be fabricated into implantable thin shape. RGO flakes could promote important factors of MSC spheroid for cardiac repair. Therefore, MSC-RGO hybrid spheroids can be used therapy for MI.
