Tissue Transplantation
Adrenal Autografting
Adrenal autografting by stereotactically placing adrenal medullary tissue within the central nervous system has been reported to alleviate symptoms in patients with Parkinson Disease . Allografts of adrenal tissue, especially from fetal donors, have also been proposed. Fetal adrenal medullary tissue stereotactically implanted in the striatum of patients with Parkinson disease has been reported to reduce rigidity and bradykinesia. However, with the ethical and political debates about the propriety of using human fetal tissue, a controlled trial large enough to adequately assess fetal neural transplantation appears unlikely. Xenografts of endocrinologically active cells from porcine donors are being tested.
