    I would have to disagree with a Teratoma being the worst type of tumor to have (albiet in ones brain of course it could present some serious issues) considering they are mostly benign and very treatable. And on the cool factor you can find some rather interesting things inside of them. I should also say gross factor, as most people do not share my ideas of what is 'cool'

    You're talking about the teeth and hair? Yeah, that's gross and cool in my book.

    I would wonder how long it would be until we can be absolutely sure that we have successfully reprogrammed these cells. I'm not sure that is possible at this point, though someone feel free to correct me on that, as I am not sure of the process.

    Yes, it seems like it's the same as stem cell differentiation after the deprogramming, and we've been working on that for some time. You can definitely get stem cells and IPSC to differentiate in culture prior to implanting. For instance the yamanaka paper or the other initial paper detailing iPSC showed you could direct differentiation into cardiac like cells which would beat in the dish. And they had other ways of showing they directed differentiation of some tissues.

    However, making a pure culture is an issue for at least neurons. Not really a good way (as of the last review paper on neurogenesis I read, a year old so I could easily be out of date) to make sure you've gotten all the cells to become postmitotic neurons. I know you can get cultures that are enriched with neurons and are at least mostly neurons, but AFAIK implanting that into a spinal cord lesion might get you teratomas there because of a few cells we can't isolate out yet. And there are probably issues with organization of neurons after that as well.

    I realize that I'm thinking only of neurons, since I work on neurogensis (sorta). I should have said that I don't think we're there for brain and spinal cord, but don't know about other tissues. Maybe we've figured out how to turn stem cells into all liver cells already. Maybe pancreatic cells, I think I remember hearing something about that. Anyway, I'd amend my statement to "we might be ready for clinical trials with some non-neural tissues with this finding."

  5. Re:Wow... on Scientists Can Grow Stem Cells In a Petri Dish · · Score: 4, Informative

    One potential problem is that they're using c-myc, an oncogene.

    From the actual paper

    Here we report the generation of stable iPSCs from human fibroblasts by directly delivering four reprogramming proteins (Oct4, Sox2, Klf4, and c-Myc) fused with a cell-penetrating peptide (CPP).

    Tumor cells are often found to have more c-myc protein than they should, and mice which have too much c-myc develop cancer much more frequently. By getting protein in rather than genes expressing the protein into cells, this is probably safer, as the cells aren't going to continue making c-myc presumably, but it is something that needs to be rigorously tested.

    I think the chances of it being anything really dangerous are pretty low. You're going to be turning individual cells with this, growing a whole bunch, and differentiating the cells before putting it into a patient. The protein only needs to work on that first cell, and proteins are turned over pretty quickly, it's likely that by the time you got to making new tissues it would already be gone, and any left over would probably be very dilluted to where it won't have an effect.

    Also, you can make these cells without it. C-myc was one of the initial four genes used to make plurpotent cells, but a short while later it was shown that c-myc only increases the efficiency. This current method is low-efficiency, and you'd expect the efficiency to drop even lower without c-myc. As the summary points out, they're already working on ways to increase the efficiency, dollars to doughnuts they're going to be trying it without c-myc in the near future.

    As far as the question in the summary

    I'd like to hear if anyone has some insight into exactly how close that brings us to everyday-use of stem cells for regenerative therapy, and exactly what obstacles remain before such therapies can be put to use."

    It puts it a lot closer. Transgenic tissues are much more worrisome than protein-treated tissues. When you give the cell new instructions for how to make proteins that can cause cancer, that's dangerous. Supplying those proteins yourself, not as much.

    There is still one major obstacle that's probably a bigger concern: we can deprogram these cells, but you want to be absolutely sure though they're reprogrammed before you put them into a patient. If you want to put new neurons into someone, you have to be sure you've turned all the iPSC into neurons. If you put undifferentiated cells into someone's brain, they tend to develop teratomas, which I think is one of the worst types of tumors to have. They're making strides on that, but I don't think they're to the point where they can say for sure that's not going to happen.

    This current breakthrough is absolutely a great thing though, don't mean to diminish it, just that there are other steps.

    But truly, where is the line? What about injecting human brain cells into mice? How about into chimps?

    The differences between mouse, chimp, and human neurons are less significant than the higher organization of neurons. I couldn't find figures for numbers of neurons in chimps or mice, but this website indicates that humans have around a hundred billion neurons in the brain, the human brain weighing 1.3-1.4kg. The chimp brain weighs 420 grams. We have more cells in our brains than mice do in their entire body.

    Injecting human neurons into a mouse? Wouldn't do anything like make the mouse self aware. It would most likely cause seizures in the mouse. I have no moral objections to it, as long as it was done with a clear research goal. Otherwise, it's probably my tax dollars at work, and those immunocompromised mice they'd be using are expensive to maintain.

    If researchers were wanting to make smarter mice, there's more to it than that. They'd first have to figure out how the human brain is made, what patterning differences exist, would have to change the mice, and wouldn't use human neurons. Again, there's not much special about them, it's the organization.

    The line here is when they start making brains that look human like in mice. And those would be so big as to crush the mice, so I'm not really worried about that.

    Anyway, why are we perpetuating this idea that biologists do morally objectionable research for kicks with their own money? Who is going to fund making a mouse think? Why would researchers be doing this? This would be expensive, would require grants, and wouldn't really have a purpose that I could see.

    Today's biology is finite component analysis done at a massive scale.. Figuring out how a machine as big as a person works is going to take millennium

    Maybe not, high-throughput molecular biology is getting better all the time.

    -With the genome sequenced we have a rough idea of how many genes there are and can find homologies between genes, so you can begin clustering genes by presumed function.

    -With mutagenesis screens, you can sometimes identify most of the genes involved in a given process.

    -High-throughput protein interaction studies can identify complexes, grouping proteins into functional groups.

    -There's an attempt to make a knockout mouse for every gene in their genome.

    None of those will give you the full story for any one gene, nor will any give you good stories for most of the genes by themselves. But used together, we can have a rough idea of what genes do what, and can take a closer look at what we need to. This gene, FOXP2 for example, was not chosen at random.

    And that's just with technology I've heard of that exists now. I don't know much about genomics, and we certainly are going to continue to invent ways to get research done faster. I think the human genome project came in under budget and ahead of schedule largely due to technology that was advanced as the project was underway. It's too early to make such long forecasts.

    More than that, I'm sure there's a natural screening process at work that gets rid of inquisitive people with good heads on their shoulders: the monotony of the job.

Managing people who look at passports all day and dealing with people who have issues with their passports might be a little more interesting, except with all the paranoia I'm sure they're in a straightjacket and have little power to do anything that someone might think will decrease security.
