with human tragedies.
마주하게 됩니다.
from one second to the other
삶을 바꿀 수 있다는 걸 깨달았습니다.
or after a car accident.
겪은 후에 말이죠.
for us neurosurgeons
굉장히 좌절시키는 건
other organs of the body,
ability for self-repair.
매우 적다는 데에 있습니다.
of your central nervous system,
심각한 손상을 입으면
with a severe handicap.
가지고 살아가게 됩니다.
the reason why I've chosen
되기로 결정했습니다.
무엇일까요?
a neurological function
다양한 수술방법을 이용하는
one of the famous ones
in the depths of the brain
치료방법입니다.
the destiny of patients
does not mean neuro-repair.
신경세포를 고치지 못합니다.
in the emergency room.
일하고 있을 때였습니다.
of patients with head trauma.
환자들을 치료해야했죠.
comes in with a severe head trauma,
머리에 외상을 입은 사람들은
his intracranial pressure.
this intracranial pressure.
a piece of swollen brain.
제거해야 합니다.
these pieces of swollen brain,
버리는 대신에
from these pieces of tissue.
길러내고 싶었습니다.
very small children
to make them thrive.
조성시켜야 합니다.
to do with these cells.
under his microscope.
현미경을 통해 본 것입니다.
as a stem cell culture,
줄기세포와 똑같이 생겼기 때문이죠.
surrounding small, immature cells.
감싸 안은 그 모습이 너무나 비슷했죠.
생물시간에 배웠듯이
of cell of the body.
성숙할 수 있습니다.
but they're very rare
있지만 매우 드물고
in deep and small niches
this kind of stem cell culture
얻어낸 것이 너무나 신기했습니다.
of swollen brain we had
intriguing observation:
발견이 있었습니다.
are very active cells --
divide very quickly.
they're immortal cells.
다르게 행동했습니다.
new cell population
but behaved differently.
to understand where they came from.
알아내기까지는 오랜시간이 걸렸습니다.
doublecortin-positive cells.
더블코르틴-양성세포들입니다.
of your cortical brain cells.
4%를 차지합니다.
during the development stage.
매우 중요합니다.
도와준 세포들입니다.
머물러 있는 걸까요?
participate in brain repair
관련되어 있다고 봅니다.
in higher concentration
뇌 손상 부위에 많이
of a potential new source of cells
an experimental paradigm.
조직검사로 떼어냈고
did it in his lab.
to track them in the brain.
these cells in a normal brain,
재이식하면 어떤 일이 있을까?"와
if we re-implant the same cells
재이식하면 어떨까?"
of professor Eric Rouiller,
에릭 호이예 교수님의 도움으로
in the normal brain
disappeared after a few weeks,
없어지는 걸 볼 수 있었습니다.
so they disappear.
사라진 것입니다.
we could observe under the microscope.
이미지를 보십시오.
that were re-implanted.
성숙한 모습입니다.
are the cells that we've labeled
염색한 세포들입니다.
to recover after a lesion?
이 세포가 도움을 줄까요?
to perform a manual dexterity task.
사용하는 훈련을 시켰습니다.
food pellets from a tray.
a plateau of performance,
익숙해졌을 때
corresponding to the hand motion.
뇌 부분을 손상시켰습니다.
to a certain extent,
자연적으로 회복합니다.
due to a brain plasticity mechanism,
회복을 하려고 노력하고
had reached his plateau
that has spontaneously recovered.
마친 원숭이입니다.
of his previous performance
보시죠.
the same individual.
똑같은 원숭이입니다.
for us, I tell you.
much more about these cells.
많은 것을 발견했습니다.
in other neuropathological models,
다른 신경병리학 실험에도
to implant them in humans.
사람에게 이식하는 것입니다.
to show you soon
도구를 가지고 있다는 것을
the tools to repair itself.
several dozen people in the audience,
어쩌면 대부분이
나아질 사람이 있는데"
somebody who can use this."
into human clinical trials?
obstacles are regulations. (Laughs)
규제입니다. (웃음)
you need to fill out
kind of trials.
작성해야 합니다.
the brain is delicate, etc.
a professional team to do it, you know?
전문가 팀도 필요합니다.
permission to start the trials,
somebody gets into a hospital
on the approval of the trial.
to do it soon?
허가가 날지 의문입니다.
this kind of study
to select the patients,
오랜 시간이 걸립니다.
to do this kind of treatment.
this to a multicentric trial.
임상 실험을 해야 합니다.
first that it's useful
이 치료법을 제공하기 전에
up for everybody.
JB: 당연하죠.
to TED and sharing this.
공유해줘서 감사합니다.
ABOUT THE SPEAKER
Jocelyne Bloch - Functional neurosurgeonJocelyne Bloch is helping to unlock potential self-healing capacities of the human brain.
Why you should listen
Swiss neurosurgeon Jocelyne Bloch is an expert in deep brain stimulation and neuromodulation for movement disorders. Her recent work focuses on cortical cells, called doublecortin, related to neurogenesis and brain repair. In collaboration with Jean François Brunet and others, she is pioneering the development of adult brain cell transplantation for patients with stroke, using their own stem cells. She aims at gathering all these novel therapeutic strategies under a common umbrella that will optimize treatment options for patients suffering from neurological impairments. She is in charge of the functional neurosurgery unit at the Lausanne University Hospital (CHUV).
