  1. Re:useless in 10 years on Umbilical Cord Blood Banking? · · Score: 1

    Actually we can do this already but it's not really made it out of the lab and into the clinic yet.

    That's because you aren't creating true "Stem cells" that can differenatiate into any tissue. You are creating 'pluropotent cells' but not anywhere near as pluropotent as a normal stem cell. Unfortunately, as far as I'm aware, no iPS cell has ever been reverted completely enough to differentiate into something useful; ie we can't figure out how to revert alpha islet cells back far enough to differentiate them into beta-cells, and given the amount of focus on trying to do this, it's doubtful that we ever will be able to. So, no, we can't "already do this already".

    We have very few clinical uses for stem cells at the moment, but it seems a fairly safe bet that in the timeframe it takes to develop these clinical applications we will also develop a reliable system for generating stem cells from our own somatic cells. I certainly wouldn't (and didn't) spend the money to store umbilical blood cells from my kids.

    I'd definitely wager against you; unless of course Bush's policy hindering the use of real stem cells was some how re-implemented. There a multitude of projects just waiting for funding to go into clinical trials. If the results are as promising as they are in rats, we could see approval in just a few years. While iPS are haven't shown promise in curing ANYTHING as they are still completely useless because they are not as pluropotent as a real stem cell.

    Ahh, I'm sorry for my lack of clarity; I failed to mention the premise that umbilical cords CONTAIN stem cells, that's what makes them so much more useful than regular tissues made up of only somatic cells.

    You are confusing pluripotency with omnipotency. Note my alpha/beta cell example. Just because we can revert to an alpha cell to a pluripotent state doesn't mean we can or ever will be able to make a beta cell from an alpha cell.

    When we will be able to reprogram them (for example) to become insulin islet cells, then we have won the battle. We will cure diabetes.

    We already do know how to do this.

    But when we will know how to reprogram them, then we will not need Umbilical cells, that aren't of much use today (although they aren't totally useless). We could easily use somatic cells (mature cells in the body) and program them to behave as we want ... some nice progress is being made on that field today ...

    I'm a researcher in this field and what you say is total BS!!! Believing this is like believing that global climate change doesn't exist. Anything you've heard contrary is just Bush pushing bad science to fuhrer his policy decisions. It's MUCH easier to differentiate a truly undifferentiated cell into a desired tissue than to revert an already matured on. It will be easier to cure cancer than preform this feat. We can't even differentiate near cousin islet alph-cells into beta-cells. If you can find a way to afford it, you'd be stupid not to bank umbilical cord. The benifits of having the cord far outweigh the cost to bank it. Hell, if you find your self in need of a bone marrow transplant, and find your child is a donor, you could potentially use the umbilical stem cells rather than put your child under the knife. If this magical 'cellar differentiation' does somehow become possible in your child's life time, then you simply stop paying the yearly up-keep fees.

    No, you are missing parts to your analogy; it should have went like this:

Later on the back home from the dealership she was unable to refill the car at the gas station because they wouldn't sell her electricity. When she later tried to go to school, she ran out of power and was stranded on the side of the road.

    Oddly, about a 1/2 hr before this story was posted I received a similar vishing scam. CallID said +23456, a guy with an American name but Indian-like accent claiming to be from the "United States Federal Grant Program" said that he was going to send me $5000 in grant money. He explained this was because I was a good taxpayer, that I didn't have any felonies, and that I can be given this money for a variety of reasons ranging from family care to school etc.. His accent, and sentence composition totally gave away that he wasn't a US paid telemarketer. Curious about how the scam worked I played along, verifying information about my address that he some how already had. He continued to explain how his company would be transferring money to me as soon as I send back the info they are going to send me. He went on to explain further, then eventually he asked for my bank account info; I deferred him until later, claiming I didn't have it, hung up and called the FBI.

    Oddly, he had such a long story, and the way he extracted info (aside from his accent) seemed pretty reasonable. I could totally see some fool (my mother) assuming that since the incoming number wasn't a normal one, that only possible explanation was that the government could be calling them.

    Strangely, the FBI took my call and I spoke with a detective, however, they were unwilling to work with me to try and catch this guy, because the amount of money he was scamming wasn't high enough; apparently he has to scam $300,000 before they will allocate any resources toward the case!!! It's no wonder there's such a problem with this type of scamming.

    If you would like to diverge from the argument that undifferentiated cells are not a complete human and take up the topic of forced medical procedures, then yes, indeed you have now found a questionable argument.

    Further you are correct, the point at which a differentiated embryo should be considered a human being is unclear. However, just because I cannot define a clear level of differentiation at which we should start to consider an embryo a human, doesn't mean that we should consider a fully undifferentiated embryo as such.

    While a similar premise to the open access mandate, its a bit off topic, nevertheless, I'll bite. I work in a supposedly "open-access environment" where we are encouraged to share, yet everyone still insists on a Nature paper rather than PLoS One Biology. It's a culture problem. Just yesterday I was having this same discussion about drug patentablity with a very pro open access co-worker, and they responded "you know I never though about." Most of the researchers I've had this conversation with conceded, that if they were guaranteed "full funding" they'd be willing to give up patent rights. The problem is most government grants fall far short of full funding. Often, government grants isn't even enough to finish out the entire research (I'm writing one up right now that won't even cover 1/10 of the project), or funding will be cut in the middle of a project due to a change of interests. Even if your project is successful, congress may not pass the additional funding needed to continue your work. This leaves Hospitals and Universities to pick up the slack, after they've already fronted the added costs of an administrative staff, security and janitorial services, HR benifits, building space, lights, computers, pens, paper, copiers, ink ect.. Until today, even if a fully funded project was to make a discovery, there was no way to bring such a drug to market due to the overwhelming costs of clinical trials. Further, just because US taxpayers paid for the development of a drug, doesn't mean the rest of the world should get it royalty free (unless the was the intention during funding, such as malaria research). That said, I can't wait for the US to follow India's lead on this one, and would happily return to engineering if they do.
