This is why funding pure science research for the sake of discovery is important. Funding only the things that have potential commercial use is hampering our research methodology in ways we only begin to comprehend.

@@oldvlognewtricks are you kidding me? I can’t tell if you’re being sarcastic or serious but there’s very little done for erectile dysfunction. I’m 23 and I had all the time from puberty all the way to 20 years old to have normal sexual health, it all went down hill after taking antidepressants, I haven’t got help with it either, viagra doesn’t help orgasm and most pills they offer to counter sexual dysfunction don’t work in everyone, medical science is far from done. I also live in chronic pain as a result of an adverse reaction to a medication, im not bluffing about this either, OP is right, more funding into science instead of wars will probably revolutionize medicine and our lives in ways majority of healthy people can’t understand. Also weight loss pills are not helping anybody, I’d compare them to viagra, they’re not the end all be all drug, they do not fix our metabolism or fix the erectile dysfunction especially if the person is overweight

IPSCs also play a huge role in research. For example they are used to grow organoids from stem cells obtained from the patient's skin cells. Then, the organoids can be studied and compared to control organoids to possibly spot the genetic origin of a certain disease.

Not only that but organoids are also used in personalised medicine and disease modelling. Although, some of the personalised medicine studies are now moving to the use of patient terminally differentiated cells. And disease mechanism studies rely more on adult stem cells instead as IPSC only give you embryonic/feotal organoids. The value of IPSCs for organoid research is really in development and aging.

[@princeofexcess]

Yamanaka factors also lead to development of reversing the age of the cell to age 0 without turning it into a pluripotent stem cell. This means we can now reverse aging the problem is safety trials as well as a delivery system. we do not know how to deliver yamanaka factors into so many different types of cells. First human trials should be finished in 2 years (restoring sight to the blind) comment if you'd like to know more!

[@allytg1]

The whole giving you cancer thing is certainly one of the main downsides! That and the spectrum of dosage, since it inevitably wont be taken up evenly.

[@waterunderthebridge7950]

This statement just feels generalized to the point it loses most accuracy. No cell cam be “turned to age 0” (not even the iPSCs) ‘cuz any living cell continues to accumulate random, spontaneous mutations. Without the ability to somehow reverse those, you will always just keep producing less and less functional (maybe even cancerous at some point) cells. The way nature circumvents the problem is summarized in the concept of natural selection (so basically, nature doesn’t solve anything really). Accumulating, disadvantageous mutations will naturally be selected against either biological (failure to complete embryonic development) or ecologically (reduced fitness). This principle works as it applies to an entire population and doesn’t work on an individual level

[@bnhcomputers4856]

You are right that delivery of Yamanaka factors into cells will be a challenge, although the recent Covid-19 vaccines represent a major advancement in delivery of mRNA to cells using lipid nanoparticles.

[@ravvingar7328]

Really really hope we can grow new healthy tissue for living beings soon. The kind of he if it that could have for stroke victims and all other sorts of ailments would be unreal.

[@bnhcomputers4856]

They are growing vascularized organoids in laboratories right now, although they are not full-sized organs. One promising technique is to obtain an animal organ, kill off all the animal cells, and have iPSC-derived human cells repopulate the extracellular matrix which serves as a 3D scaffold for the cells to grow. Yet another interesting technique is the 3D printing of cells using a biological 3D printer. Replacing old tissue in the patient with young tissue would probably go a long way toward extending human lifespan.

[@neuswoesje590]

I wonder if if they can grow organs from the patient's stemcells it means that they would no longer need immunosuppressants since their body would hopefully not reject it, which would mean they aren't so at risk for diseases. I really hope so!

[@bnhcomputers4856]

@@neuswoesje590 That is absolutely correct, and that is one reason why there is so much excitement around iPSCs. Organs and tissues made from a patient's own cells are not rejected by the patient's immune system because the cells of the organ/tissue will display proteins (i.e. MHC and other proteins) on the cell surface. The immune cells (i.e. T cells and natural killer cells) will recognize those proteins as "self" and regard the cells as friendly. The other reason why iPSCs are exciting is because they can divide endlessly, so it is possible to make as many iPSC-derived cells, tissues, and organs as needed by the patient. This has the potential to revolutionize the organ transplant industry, and maybe allow us to live longer, more productive lives. However, iPSCs have an important drawback. iPSCs carry a high risk of forming cancerous teratomas when injected into an animal host. Cell therapies and organs/tissues based on iPSCs always carry the risk that some undifferentiated iPSCs may remain in the cells, organs, or tissues to be transplanted into the patient, thus exposing the patient to cancer risk. On the other hand, adult pluripotent stem cells such as VSELs and Muse cells do not form cancerous teratomas and do not carry any cancer risk. Like iPSCs, they are obtained from the patient, carry the patient's DNA, are recognized as friendly by the patient's immune system, are pluripotent, and can differentiate into any cell type. Some adult pluripotent stem cells have demonstrated practically limitless number of cell divisions [Ref: Henry E. Young, Asa C. Black, "Adult-derived stem cells" 2005. Cancer Gene Mechanisms And Gene Therapy]. Furthermore, when adult pluripotent stem cells are injected intravenously into the patient or animal host, the cells automatically migrate to areas of damage in the body, and then differentiate and engraft into the tissue at a high level of efficiency (typically greater than 20%). Thus, repair is long-term, as opposed to the short-term effects of other types of cell therapy such as MSC therapy. Muse cells are now in clinical trials in Japan.

[@processingpodcastseattle]

Thanks! We love SciShow.

[@rimigill]

Great video! One of the things you didn’t mention is although the iPSC themselves aren’t used for many approved therapies, there are many iPSC DERIVED cell therapies in the clinic and in trials such as immune cell transplants to treat cancer. These offer huge off the shelf potential even if it’s not the iPSC themselves but the differentiated cell lineage

[@bnhcomputers4856]

Yes agreed, there is still good potential for iPSC-derived cell therapy in the future, so I slightly disagree with the pessimistic outlook of this video. For example, there is now a clinical trial for treating Type I Diabetes with iPSC-derived pancreatic beta cells "off the shelf". (For more info, search ViaCyte). These cells are genetically modified to evade the host immune system, as MHC genes have been deleted by CRISPR. From the FDA's standpoint, iPSC-derived cells are risky because they may be contaminated with undifferentiated iPSCs, which are known to cause cancerous teratomas in mice. In recent years, techniques have been developed to solve this problem by killing off, sorting out, or culturing away the undifferentiated iPSCs before injecting the cells into the patient. However, it is difficult to be absolutely sure that every last undifferentiated iPSC has been removed from the cells, when only one single iPSC cell may be enough to cause cancer in the patient. I think that it is only a matter of time before these techniques are advanced enough to convince the FDA to routinely approve iPSC-based therapies, but the question is, "how long?"

[@NECRO1369]

Would be nice to see this advance more in nerves and skin regeneration. Burnt my eyelids off years ago and still waitin to get new eyelids to progress towards getting my eyesight back.

[@latimil838]

Although we don't have a lot of clinical trials using iPSCs, we do have an considerable number of stem cell teraphie studies (both in human and rodents). Lately, a lot of progress has been made to study the use of extracellular vesicles released from these stem cells as therapy source. They have the benefit of not being able to mutate after injection. There's a lot to say about that (trust me I know, I work in a lab that study the use of those for stroke therapy), but I dare to say that future is promising (even if expensive at the begging)

[@ConstantChaos1]

There are some developments you might have missed, we have successfully grown (mini) human eyes, there are a relatively new class of polymer gels that have promising futures for neuron regeneration, and if I recall correctly there have been advances in specifically optical implants but with the guy who has the flashlight prosthetic I can't find the articles for the last one, sorry

[@zatar123]

This also has tie-ins to cancer researcher Given that cancer is basically just stem cells running amuck, and there is evidence that the same process that causes stem cells to specialize into a given cell type can cause cancer cells to revert back to being normal cells.

[@bnhcomputers4856]

Recently, studies have shown that cancer cells can be converted back into normal cells, and even differentiate, by inhibiting certain ion channels (e.g. potassium ion channels) in their plasma membrane. Because this effect is seen in a wide variety of ion channels, there is a hypothesis that electric membrane potential (i.e. voltage across the membrane) may drive cancer. Cancer cells are known to be electrically different than normal cells. Interestingly, after ion channel inhibition, the effect seems to be permanent and long-lasting. This indicates that the long-term state of the cancer cell has changed upon ion channel inhibition. In addition, ion channel inhibition may be relatively non-toxic to normal cells, at least compared to existing chemotherapy drugs. Aged and/or senescent cells also seem to have abnormal electric membrane potential compared to normal or young cells, and it would be interesting to see whether ion channel inhibition might provide a long-term, anti-aging effect on aged tissues. For more info, search Michael Levin and "cancer". He is also on KZbin.

[@kae8450]

The main issue why ipsc is found to have more mutations is because 1. Cells that are reprogrammed may already contained some levels of mutations that is carried forward after it is reprogrammed. 2. Most reprogramming methods involved integration of extra genetic materials that knocks in the genes randomly, causes random mutations to occur. It’d be a good idea to monitor and often sequence the genome to monitor these mutations from occurring. In a preventive effort, may need to use a non-integrating methods in ipsc generation. But of course currently it’s not that efficient, maybe the next person to produce a mutation-free ipsc might get a nobel prize 🤷🏻‍♂️

[@Geroscientist]

As someone in the field, there is so much more to this story that was missed - it might even 'reverse aging'. Epigenetic reprogramming can be applied in live animals to partly 'reverse aging', which has been shown by top labs (e.g. Belmonte, Serrano, Sinclair) in multiple different organs. Altos labs recently got $3B funding from people like Bezos, likely the largest startup raise in history, just to advance this research. This technique is specifically known as partial epigenetic reprogramming, which unlike 'full' reprogramming, aims to rejuvenate adult cells without taking them back all the way to stem cells (which would become a tumor). Not only does this have the potential to reverse age-related diseases like glaucoma or Alzheimer's, it might also treat genetic orphan diseases like progeria.

A weird take on iPSC research, because literally everyone predicted they would first be useful for basic research. Apart from people raising funds for their start-ups, everyone also knew most of the first clinical trials would fail. That's just statistically what happens with new technology in biology, and there were concerns very early on that iPSC weren't equivalent to normal PSC, and that the yield is just too low. I don't the hype for iPSC has ever died down, and many cell biologists concerned with medical applications are still working on making it work, either by optimisation of the methods, or combining it with other ideas.
