Their test also revealed evidence of dying β cells in the blood of people who had received islet cell transplants — a potential
sign of immune rejection of the islets.
These stem cells, termed endometrial regenerative cells (ERCs), are not only harvested in a noninvasive manner and relatively readily available in large quantities, but they potentially overcome the
problem of immune rejection in many female patients as well.
The cells were derived from eggs that had been injected with DNA from the patients, so they could eventually be transplanted back to replace or correct the patient's diseased cells without
fear of immune rejection.
«Nonetheless,» says Boyd, «it's exciting to think that, if we can overcome the
issues of immune rejection, the millions of people whose quality of life — if not life itself — is being compromised because of chronic diseases may all be treatable with the help of this technology.
Patients could benefit from having their own cells reprogrammed into ones that could help treat disease, potentially eliminating the
prospect of immune rejection.
If he could wipe all the cells from the phallus, or any other organ, he could then reseed it with cells taken directly from the intended recipient, virtually eliminating the
possibility of an immune rejection.
The landmark achievement revives the hope of being able to generate new tissues using a patient's own cells, eliminating the
risk of immune rejection.
Essential to this process are induced pluripotent stem cells (iPSCs), which can be created from a patient's own tissues, thus eliminating the risk
of immune rejection.
