Xenotransplant, autotransplant or donated human cells? Hi Jim: I read your earlier messages about being on that committee. Congratulations and Good Work! Your personal story (your diary) makes fascinating reading. Which do you believe will be first to become a practical procedure that some of us mat participate in?: - Xenotransplant = cells from another species, probably porcine cells; or - Autotransplant = collection, processing and implanting of one's own cells; or - Donated human cells = the collecting, processing and implantation of cells of a third party (parties); or - Other cell implant protocol?
