How To Grow a Head 355

Posted by CmdrTaco from the no-not-like-that dept.
Taco Cowboy writes "British scientists have found a mechanism within our gene sequence that allows the growing of a new head — with brains, etc. The gene is tentatively known as smed-prep, and the information contained in smed-prep also makes the new cells appear in the right place and organise themselves into working structures."

      At the moment, this only works for flatworms, whose purchasing power is rather limited, last time I checked. So I doubt they will make a fortune soon. Then again, the difference between a banker and a flatworm is probably somewhat negligible. Actually, no, I am sorry. My sincerest apologies to all the flatworms reading slashdot.

    From what I gather, they figured out the gene sequence in flatworms for growing another head for a flatworm, and can do so consistently.

    Since our genes are similar, they probably can figure out where the genes for growing a human head are, and *might* be able to use that info for regenerating damaged brain tissue

      In particular, it mostly illustrates that in flatworms, body plan genes can be routinely reactivated throughout an organism's life. Most multicellular animals on Earth have a series of genes known as Hox or homeobox genes whose role is to determine the correct placement of structures on the body- depending on the form of the organism, "structures" can mean things like organs, limbs, eyes, tails, etc. The activity of these genes is so important that they tend to have been strongly conserved sequences throughout time- we have some Hox genes that are very similar to those in flies, for instance. This conservation is helped along by the fact that the Hox genes ultimately work by signaling other genes to work; the signaling cascade functions whether the signal is for the development of insect wings or for bird wings.

      According to the paper, the signaling involved in the development of the posterior end of planaria (Wnt/beta-catenin) had already been identified; the discovery of Smed-prep explains how the development of anterior structures (the trunk and head of the animal) are regulated. In addition, they found that the anterior and posterior pathways normally work in opposition (to avoid growing a tail on the head or head on the tail), and by silencing the posterior signaling, then activating head regeneration, a head would grow at both ends.

      From what we know of human Hox genes, the picture is not so simple- even at the most basic level of developmental organization there are several genes that direct development of the head, so there isn't a master gene we can reactivate to grow an ectopic head, but many of the same developmental pathways (Wnt, for instance) are the same or similar across organisms.

    Those are not the body parts we seek.

    • Seriously, of all the body parts for scientists to figure out how to grow, the head has to be the least important one. When the head is gone, you just harvest the organs for others people to use. If a person needs a new head, then you really need a person. If you can figure out how to grow extremities or organs, then you're onto something!

      Better yet, grow me a whole new body, sans brain, and transplant mine. That'd be awesome!

    Science always advances faster then the moral and ethics of the society.

    Science Fiction tends to serve as the cursory warning of the abuses of science. Please reply with suggetsions on reading that our fellow scientists should watch when they are not busy playing God (in the figurative sense.)

    The Island comes to mind but even comic books like the Micronauts foretold the warnings of Body Bank abuses. The Repo Men is a recent film that from what I can gather might also make for a good reading.

    Oh how I wish that science would first think:
    "Ok if this works what are the ethics" rather then "do it first, then we'll worry about the ethics later."

    I'm all for science, I just have the crippling burden of being a history buff, knowing how often science gives birth to atrocities. Comparing post-1600s science has made religion look tame.

      Science doesn't think anything. It's a process. Plenty of scientists can be assumed to have chosen morality over science. You don't hear about them because they didn't do anything. All scientific progress can be put to ends both good and ill, there is therefore nothing ethical or unethical about science fact, only the actions of men.

        This is very true. Just look at Nobel [wikipedia.org] [Wikipedia]. When designed nitroglycerin, he was trying to make a safer explosive for miners. Instead he made a tool of war and was horrified by it. It was not his morality nor his invention that was flawed. It was the people who used it. I would think by now that our society had moved past the base point of science is evil and technology is amoral. That cell phone in your pocket could be used to make a bomb threat or call an ambulance for the guy having a heart attack. As for this research, it is quite a ways off from any useful/practical applications. But people hope that when it does come to fruition, it will be for things first like severe brain damage cause by an accident, a blood clot or other damage. And while yes, planarians have a cephalic ganglia (brain) and a complex nervous system for being a simple invertebrate, it is vastly less complex than even a mouse brain. As a case in point, their "eyes" are a photoreceptor not a lens, so while they can see and react to light, they do not have the capability to distinguish shapes. Disclaimer: I work in a research lab that uses S. mediterranea, the flatworm used in this paper.
