Thanks for your question!!
I get the small vesicles from mouse cells and I am now using them on mouse cells as well. I am starting a new project to get them from human cells and treat human heart muscle cells with them(we get them from patients or from embryonic cells). I am very excited about this project. We are also going to start using the vesicles in mouse hearts that have had a heart attack. This areusually the steps you need to follow before even thinking in using our research in humans.
