it's more in the gdnf/bdnf mode of action, rescues damaged neurons. pig cells secrete growth factors so they are not selecting most advanced patients for the LCT phase2b trial.

don't discount fetal neuron implants, they successfully reversed advanced pd and the benefit lasted years. recent autopsies of patients receiving these implants in 1990's, early 2000's, show implanted neurons survived.

canadians and europeans working on improved implant techniques.

as far as LCT, you'd have to go to NZ for the implants if their procedure gets approved.y phase1 pd trials involving drilling a hole in your head has been successful and then most had a failed phase 2 when blinding/placebo added. keep your fingers crossed.
