Аннотация:Since 1954, almost any organ or tissue or body part of the human body has been transplanted, with the notable exception of the central nervous system (CNS). While cell graft trials into diseased brains, spinal cords, and retinas have been conducted since the end of the XX century, transplantation of segments of the spinal cord (SC) to treat spinal cord injury (SCI) or transplantation of the whole brain tout court is considered out of reach, due to impassable biologic and – in the case of the brain – ethical hurdles.Nerve fusion technology developed over the past 40 years, including the GEMINI SC fusion (SCF) protocol, aims at enabling spinal cord transplantation (SCT) and optic nerve (ON) reconstruction in the setting of eye transplantation. Brain transplantation is discussed elsewhere.
