How we could teach our bodies to heal faster | Kaitlyn Sadtler

2754 ratings | 120255 views
What if we could help our bodies heal faster and without scars, like Wolverine in X-Men? TED Fellow Kaitlyn Sadtler is working to make this dream a reality by developing new biomaterials that could change how our immune system responds to injuries. In this quick talk, she shows the different ways these products could help the body regenerate.

Regenerative immune system is the #future
Sasha Pollard (30 days ago)
Everyone's body is different. If you think about it, their is no right answer. The immune system is something that fights off diseases, colds etc. When your immune system is weakened, then something will happen negatively to your body. It's about taking care of yourself. Also taking care of your mental health.

Jai Maa (1 month ago)
yes, there would be patches for recovery of injuries to buy in the supermarket, similar how today we buy paracetamol or other drugs, but in reality there is the moral hazard of how many pills can/should one take/buy. It is a shortcut, a lazy one yes, could heal by yourself, easier, faster, but some prefer to buy paracetamol and move on. It is learning to heal oneself, to know you can master your own body defence system. One can/should seek assistance at times, but a doctor does not cure anything, but oneself gives authority for such and such treatment to function and get the body into a recovery. Again is the conviction that the human body has an innate ability to master oneself body and mind, and to operate at perfect rate, whatever this is, low or high, will depend on the individual and circumstances. thank you
Jai Maa (1 month ago)
we all have seen this already!! The key for healing, not faster or slower, but healing (e.g. full stop, end of the paragraph). Each individual has a unique body metabolism, this is the speed or velocity at which his/her brain nerve cells make a contact, synapsis!! a connection that sends an instruction, one that is received, one first instruction that triggers a reaction of chain recovery for an unwanted tumour, a wound, an emotional scar or even a more ethereal glitch that triggers all other reactions. Something that makes a comeback on a sublevel and makes the body react and gain confidence in the healing process until the individual is healed. 2. First is Heisenberg principle, either velocity or position are determined at once (this principle is also valid and applied for more than two dependent variables. A beam of light is required to be thrown at a particle's trajectory to determining its position. At this point velocity slows down to near O. 3. If a child falls down on a playground, and injures/have an accident of some sort, him/herself badly, bleeds, looks for mum/dad and seeks all ATTENTION possible. Parents rush to hospital, he/she is healed and his/her trust in parents ability to care/heal him/her is enhanced every time this happens. However if the same occurs in a playground while parents are away (ok. momentarily). The child will get up, dust off, cry a bit less, wondered around fro a while and go back to play. When parents arrive find him in blood, in half the pain, half the requirement of before (yes, could be dead as well, depending on the injury). True some elderly have been left unattended/neglected in severe pain in hospital corridors, wards, often when medical assistance is more needed. But ATTENTION will always slow recovery, it is key. When the brain has other activities that requires to be healthy, fit, up and running; it will begin recovery. Mind acts more clearly when it is clean from nasty chemicals, and pollution of some sort which creates blockages in the speed of metabolism and the ability to heal itself. There is an equilibrium in the body (which is a mind in itself), which is determined by freedom of movement; much like that of 'eat as much as you like' some will take 400kcal , some 700kcal, some 1000kcal, some 300kcal in one meal. There is a natural revolution or frequency one particle can take, including its maximum and minimum velocity points of the trajectory for the particle. 4. Doctors and patients alike should enter into a two way compromise agreement, a contract. You do this , We (doctor and health system) do this. 5. Health systems are a bit like a supermarket. Go & see, you may buy or not, try later or throw away, try something else. very expensively and costly on either side, highly demanding, and inefficient. UK NHS for example prescribes only the right amount of drug required for a treatment, which it is good, but too many unnecessary drugs are prescribed. Patients must take more responsibility/accountability in the recovery/healing process. Salvation = healing comes from the true conviction; I am healed, I am cleaned and my body is/will be too (at some point one may also die). Thank you

I've seen shark bite victims lose large amounts of muscle tissue that never gets rebuilt. Will that be possible with your treatments?
ONCE - Englandson Lim (1 month ago)
No need to send signals to our cells, because our body knows how to rebuild our body parts. Just give it the raw materials like proteins and vitamins so that our body can regenerate on its own. We need nutritionists more than immunologists!

Subsonic Hypixia (1 month ago)
But the thing I’m wondering is 1. How do you plan to put the T Helper into wounds? Injection that can make people uncomfortable? Or tablets which can take too long or even liquid form which can sting ALOT. 2. How do you plan to afford this
Connor Lynch (1 month ago)
I assume the process will be more like adminstering immunomodulatory molecules to make the patient's Th cells play nice. I assume if you have severe muscle scarring you won't be too upset about getting an injection. Although yeah, I'm sure even once this has been developed it will be ludicrously expensive for years afterwards

ok and how do I teach my body to heal faster in a practical way ?
Connor Lynch (1 month ago)
Immune cells can help you heal wounds; certain molecules can prompt immune cells to heal wounds; creating materials imbued with these molecules could potentially prevent scarring during wound healing and maybe even act as a scaffold for growing lost body parts.

I am also curious how they can make this material only work where it's needed rather that grow back stuff that was removed (like tonsils, appendix, hymen etc)

mild soup I didn’t automatically go there, but YOU called me a troll and I was merely stating my researched perspective. 🤔
mild soup (1 month ago)
And (once again I know this maybe pointless to tell you) but even though most vaccines have taken mercy out the ones that do have them in cannot be counted as the same molecule, chemical properties change when atoms bond. Much like a poisonous gas and a vloital metal combined make table salt.

Well, while we have you here....I had a family member of a family member who lost his finger tips in an accident several years back and the doctors wrapped them up and used powder from a pig’s bladder and he regrew his finger tips over the course of many months. They didn’t look like nothing happened, but that is better than losing them. Is that stem cell treatment something the Helper T cells would enhance?

K S Hi Kaitlyn, good to know that it's not on purpose because it somehow made you looked a bit arrogant, which in turn diminished the clarity of your talk, to me and some other people (due to some psychological defensiveness). But eitherway, you and your team's research is really exciting and spectacular! Thanks for all your efforts! :)
K S (1 month ago)
You raise a very valid concern & I had to make an account to respond, because as a speaker saying "I" is difficult, as research is 100% done in teams. We were instructed to speak in I/I'm, which is the *only* reason it was worded that way, original drafts had "we". I hope this clarified why it was worded in that manner, I've cited the original work done by the teams on the TED page.

Arent the same blood cells responsible for scar tissue also used to stop the bleeding in the first place? I doubt you can just trick the body this easily and have no repercussions.
Connor Lynch (1 month ago)
Platelets and clotting factor proteins in the blood prevent bleeding; switching T cells and macrophages to be more recovery-based shouldn't affect this in theory. Although I have to agree that we really don't understand the finer details of our immune system well enough to expect no side effects from this...

I'm surprised axolotls weren't mentioned, many lizards can regrow parts, but axolotls, as well as starfish, are some of the kings of regeneration. Still though, very interesting thought. A few years ago I had a number of life-saving surgeries, but the aftereffects of cutting into my head and abdomen have left some fairly major, and quality of life decreasing side effects. Being able to minimize, or even prevent some of these would be huge.
Level Joe (1 month ago)
+fealubryne you didn't ramble at all and I was concerned about that too with my own post. Going to mull over your comments... I just Thanks for your time and God willing, I hope you live a long fulfilling life. We all serve a purpose and maybe our conversation is part of that?
fealubryne (1 month ago)
First off, no worries on your comment, I'll never turn down a thoughtful conversation. Financially speaking, no, I most likely will never be able to contribute financially to any great degree. Between surgeries, I've worked since I was 13, so it's not always been like this. I've long since come to terms with the fact that I'd be lucky to see my 7-year-old daughter graduate college, and most of my family is aware as well, and so it's been made fairly clear that there should be no heroics done to save me should things seriously go downhill. I do think healthcare should be available to everyone, in many cases better healthcare, as well as more research put into preventing illnesses before they start, or stopping them before they cause irreparable damage should be done. In many cases, prevention is key to stopping problems snowballing into major, expensive issues. If my illness had been caught and properly diagnosed sooner I could've forgone half of the surgeries and hospitalizations. I'm in a wheelchair because of complications from an illness running rampant through my teen years, and those issues could have been prevented, but now we can only wait for problems to arise and attempt to keep them from getting worse. There most certainly should be limitations to medical care and the extents gone to assist someone, and to a degree, exist already. In a lot of cases, elders are only given figurative band-aids, because expensive, dangerous surgeries or treatments have little point for them. Particularly expensive, or rare chances at medication or therapy are given to those with the absolute best odds of surviving/utilizing them. Even the Hippocratic oath suggests that physicians "help the sick according to [their] ability and judgment." It becomes a balance of that and ethics none of which are overly clear which is an excess of spending or assisting and which is a deficiency in medical care. Financial calculations and logic are cold and unflappable, but should never be utilized alone when making decisions alone. Not that I'm saying you suggested it, but just putting it out there. All the things you mention should most certainly be a part of the grand scheme of things, though I heavily suspect all hospitals have had their own balance of those things and incorporated it into their own policy. In my opinion, if there isn't already a general guide for all hospitals, it would make sense for there to be at some point. But I also feel there should be more transparency when it comes to medical care, to an extent. Hopefully this makes sense and isn't a bunch rambling, though if it is I apologize. I'm not always the best at conversations, my brain tends to go in circles sometimes and I come across wrong.
Level Joe (1 month ago)
First off, I hope to never go through what you did and I'm truly sorry you had/have to. Second, if my questions offend you in anyway let me know and I will delete my post. Here we go... More than likely, you will never contribute enough financially to society to pay for what has been done to you. Do we spend millions of dollars to save the life of an 80 year old man who may live another year or two or ten? We deny liver transplants to those who can't quit drinking. I know the difference is self-destruction versus natural causes but when does society have this conversation? Don't get me wrong, I'm glad you're here but (self preservation aside) where does risk, quality and reward vs resources and financial cost enter into the equation? or Does it ever enter the equation and should it? Lots of people are asking for healthcare for all but we have to decide what lines need to be drawn and where. I asked you because you've been down that road. My wife and I have DNR's because of this.

Combine this with teaching patients to use their focused attention to heal themselves. Going only at the biomechanical scale will work alright, yet when we also engage focused conscious willpower I think we'll see the full results we want. holohealing.com
