    Grey’s Anatomy neurosurgeons perform a “groundbreaking procedure” to cure Parkinson’s.

    Gray’s Anatomy neurosurgeons carry out a “groundbreaking process” to remedy Parkinson’s.

    It’s common for TV to fast-track medical innovation. Take the present season of Gray’s Anatomy, which featured a serious storyline a few “remedy” for Parkinson’s illness. The drama sequence adopted a staff of researchers and docs as they used a groundbreaking surgical process utilizing skin-derived stem cells.

    In actual life, regardless of a long time of analysis and big positive aspects in technical information round stem cell therapies for Parkinson’s illness, these remedies stay out of attain for most individuals with the illness. Parkinson’s is a mind dysfunction that worsens over time and causes the demise of sure nerve cells that usually produce dopamine, which helps coordinate muscle motion. Probably the most generally used surgical therapy for Parkinson’s is deep mind stimulation, which delivers electrical pulses to mind areas affecting motor signs, reminiscent of tremors and rigidity.

    Nonetheless, given the stakes of this persistent progressive neurological illness going through about 1 million People, it’s value unpacking simply how far-fetched the Hollywood depiction is – or isn’t.

    On the present, docs take stem cells from a pores and skin biopsy of a personality with Parkinson’s illness and, “by means of a fancy course of,” rework these cells into dopamine-producing cells. Individuals with Parkinson’s sometimes have low dopamine ranges within the putamen, part of the mind concerned in motion. By injecting new dopamine-producing cells into the character’s forebrain, the place the putamen is discovered, the docs purpose to spice up dopamine ranges.

    The process kicks off with a CT scan, which supplies the surgical staff pictures of what’s described as “an interactive 3D roadmap” of the character’s mind. After a number of extra fast steps – together with drilling of burr holes to forestall stress from increase within the mind – a robotic arm brings a hole needle into place. A researcher then removes the stem cells from a cooler and examines them underneath a microscope to substantiate that sufficient cells are alive. Lastly, the cells are injected into the character’s forebrain, beginning with one facet after which shifting to the opposite.

    A lot of what’s depicted on the present is sensible – if simplified and futuristic – in response to Willard Kasoff, MD, an affiliate professor of neurosurgery on the Lewis Katz Faculty of Drugs at Temple College and director of stereotactic and purposeful neurosurgery at Temple College Hospital.

    “It is not science fiction, but it surely’s a future present,” he says.

    Grey’s Anatomy doctors celebrate after a successful Parkinson’s surgery.

    Gray’s Anatomy docs have a good time after a profitable Parkinson’s surgical procedure.

    There have been a number of thrilling stem cell improvements concentrating on Parkinson’s in recent times that, on the floor, are harking back to Gray’s Anatomy’s televised “remedy.”

    In 2017 and 2018, as an example, docs reprogrammed pores and skin cells taken from an individual with Parkinson’s to create “alternative dopamine neurons,” which received implanted into the individual’s mind. Extra lately, a scientific trial concerned injecting stem cells into the brains of individuals with Parkinson’s as a way to restore their dopamine ranges, full with a GPS-like mind scan displaying neurosurgeons the place to inject the cells. Upcoming scientific trials can even use Parkinson’s sufferers’ pores and skin cells to provide alternative dopamine neurons for transplantation.

    However such remedies received’t essentially be broadly out there anytime quickly, in response to Kasoff. “Cell transplantation is extremely tough and sophisticated,” he says. “It has been labored on for many years, and it is nonetheless early, early analysis trials. So even that sort of remedy is probably going years and years away.”

    A number of the therapies depend on genetic engineering to transform stem cells into neural progenitor cells, which may develop into numerous cell varieties discovered within the mind – a course of often called differentiating. Neurosurgeons may also direct how neural progenitor cells change, reminiscent of guiding them to change into dopamine neurons. The hope is that after these cells are transplanted into the mind, they’ll “work out what to do, or be advised what to do by the encircling cells,” says Kasoff.

    Even when the trials succeed, they could not characterize a remedy. As a result of the remedies are directed on the putamen and the substantia nigra (an space the place neuron loss can have an effect on dopamine ranges), they solely deal with motor signs. Parkinson’s illness additionally impacts considering abilities, steadiness, and different features all through the physique. Cognitive decline can result in dementia and demise.

    “The thought you could remedy Parkinson’s by placing cells within the substantia nigra or the putamen might be not true,” Kasoff says.

    Additionally, Parkinson’s is usually considered a illness of 1 cell kind: the dopaminergic cells within the substantia nigra. However in actuality, Kasoff explains, it’s seemingly a illness with “1000’s of cell varieties,” which makes any potential stem cell-derived remedy extraordinarily advanced. Sort 1 diabetes, however, is a illness of just one cell kind, and new remedies utilizing insulin-producing cells derived from stem cells might quantity to a remedy.

    As for Parkinson’s, says Kasoff, “it could be that the subsequent stem cell trial hits the jackpot, after which we’ll be on to the subsequent step.” That would imply determining the place to transplant stem cells for the cognitive and balance-related signs of the illness, as an example.

    In the end, he says, “the hope is that what occurs on the present is strictly what is going to occur in some unspecified time in the future sooner or later.”
