Take some cells from a patient, grow them in a laboratory for a few weeks, and then inject them back into the same patient. That's the basis for autologous cellular therapy, a rapidly developing field that promises to revolutionize the treatment of conditions from cancer to crow's feet.

Growing the cells can be quite labor-intensive, however, because they must be transferred into increasingly larger flasks as they propagate.
