R egeneration of damaged myocardium is still a big challenge in clinic. Stem cell therapy has shed light to regenerate the ischemic myocardium. However, low survival rate of transplanted stem cells, very low terminal differentiation of transplanted stem cells, and serious fibrosis of infarcted zone limit therapeutic effects of stem cell to achieve functional and structural regeneration of ischemic myocardium. Recent studies have shown that supporting niche cells which are consisted in cardiac unit in myocardium might play an important role in regeneration of myocardium. A novel interstitial cell, named as telocyte, has been identified recently in heart interstitium. Recently we reported that cardiac telocyte (CTs) network in myocardium was impaired during myocardial infarction (MI). In addition, transplantation of CTs in both infarcted and border zone of myocardium simultaneously was able to decrease the infarct size and improve the myocardial function. Our up-to- date study further revealed that the midterm therapeutic effects (decrease of infarct size and improve myocardial function) of CTs transplantation for MI was maintained till 14 weeks. The cellular mechanism of therapeutic effects using CTs for MI was attributed to increasing of angiogenesis, improving CT network reconstruction and decreasing fibrosis in ischemic myocardium. The finding of our study suggested that therapeutic effects using CTs was able to maintained at least for 14 weeks. The CT therapy would be considered as one of the potential novel cell therapies for MI. The CTs have high potential to be applied to regenerate MI used alone or tandem stem cells.
