Mesenchymal stem cells are pluripotent cells capable of differentiating into myocardial and vascular endothelial cells. The present invention demonstrates that the mesenchymal stem cell sheet have therapeutic potential for a severely damaged heart due to its pluripotency and in situ self-renewal capability. Mesenchymal stem cells derived from adipose tissue were cultured to prepare a mesenchymal stem cell sheet. Four weeks after induction of myocardial infarction in rats, the mesenchymal stem cell sheet was transplanted to the heart. The mesenchymal stem cell sheet were readily engrafted to the surface of the scarred myocardium, grew gradually in situ, and formed a thick layer (approximately 600 μm) in 4 weeks. The grown transplanted mesenchymal tissue contained newly formed blood vessels, myocardial cells, and undifferentiated mesenchymal cells. The engrafted mesenchymal stem cells inhibited thinning of the myocardial wall in the scar area, and improved cardiac function and survival rate in rats with myocardial infarcts. Thus, mesenchymal stem cell sheet transplantation may represent a novel therapeutic approach for myocardial tissue regeneration.

Catheters and methods for their use are presented that provide automated delivery of cells to structures in the body such as degenerative or weak muscle. The catheters contain one or more sensing components and a system for delivery of cells such as autologous myogenic cells. The sensing component(s) triggers automatic discharge of the cells upon detection of a body surface that needs repair. The discharge of cells may occur through an automated lancing mechanism that alleviates operator error from manual injection timing. During use, an operator can position the catheter end to a structure in need of cellular repair, and the device can automatically discharge cells at a location and time as determined by conditions sensed at the catheter end. A catheter and system is particularly useful for repair of degenerative and or weak heart muscle, such as that found after a myocardial infarct. The catheters and methods of their use also may be used for cellular repair of other interior body structures, particularly muscles such as bladder, intestine, stomach and diaphram. The catheters provide greater use of myogenic cell therapy for heart disease, while avoiding complications of open heart surgery.
