Abstract

Optogenetics Applied to Motorneuron Control: Nerves damaged by disease or injury do not always regenerate. In such cases, therapies involving transplanted stem cells show some promise. However, the new neurons derived from transplanted cells cannot communicate with the central control systems that would normally regulate movement. To avoid the need for such communication, in a proof-of-principle study, Bryson et al. (p. 94 ; see the Perspective by Iyer and Delp ) added optogenetic control to differentiation and transplantation of motor neurons. In the mouse, these engineered neurons were able to reestablish connections within a damaged sciatic nerve and, when activated by localized light stimulation, could drive muscle contractions.

  • Engrafting embryonic stem cell-derived motor neurons expressing channelrhodopsin-2 into a denervated peripheral nerve demonstrated that regenerative medicine and optic stimulation can be used together to reinnervate peripheral nerves.

    “The results demonstrated that regenerative medicine and optic stimulation can be used together to reinnervate peripheral nerves [134].”

    From Interfaces with the peripheral nervous system for the control of a neuroprosthetic limb: a review (2020) · cites this paper as [134]

    The Abstract reports that stem cell–derived ChR2 motor neurons were engrafted into partially denervated peripheral nerve branches and, with optical stimulation, restored muscle function. It says the grafted neurons reinnervated denervated muscle fibers, not that they reinnervated peripheral nerves. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
