Worm “operating table” in the diagram

U.S. researchers have successfully built up specifically for the 1 mm size worms tailored “operating table”, it can be recycled to the worm’s nervous system and other structural aspects of the worm “surgery.”

According to scientists, due to worms and humans have a lot in common, the research on the worm may well serve humanity, it would help solve the restoration of the human spine, nervous system and digestion with the many problems This research is now published in the “NatureMethods” magazine, received from the concerns of scientists around the world. .

It is reported that, in order to more in-depth study of the worm, Texas State University, Adela? This? Yacar (AdelaBen-Yakar) Professor and Frederick? Bourjois (FredericBourgeois) professor and his team Through a long and ultimately successful in 1-millimeter-long worm built a “mini-operating table.”

In the “operating table”, the scientists will use a special chip that has two compartments of the “operating table” using a membrane separation of the constant pressure in the air so that the worm securely, and then use laser Scalpel Cut off the worm’s nervous system, then scientists can carefully to the worm’s nerve regeneration was observed and studied.

Scientists 10 years ago has successfully been decrypted worm genes. At that time a total of 1,500 scientists in 250 laboratories, spending 15 years, spent 3 million pounds to complete this great work. Scientists found a 9 1 000 7 1 million genetic code and 20 000 gene pairs.

This project, the British head of John? Sulston (JohnSulston) has thus won the Nobel Prize. He has said that the worm is like a “micro-model of human internal structure” (amicrocosm of humanity in terms of the mechanism inside).

Fact, Sulston’s remarks are not unfounded. With a new rod called nematodes (Caenorhabditiselegans) to small-scale examples of soil nematodes. Although the new worm rod constituted by the less than 1000 cells, but only 1 mm long, but it has striking similarities to human nature, such as cell division, cell recognition and cell death.

In addition, it has experienced by the human embryo to the mature individual life journey. The new rod-shaped worm body nerves, muscles and skin have everything, taste and even the body of these structures is the inherent degree of similarity to human cells is also unusually high, 40% of similarity.

As worms and humans in the nervous system has a striking similarity, so the worm has a very important for humans, the research value, but also the significance of the operating table is very important.

According to experts, introduced in the “operating table”, the worm can be arbitrary in addition to release and grasp, the operating table can also be flexible to different according to the size of the worm adjustment, which will allow scientists free operation, while the worm can be easily observed nerve regeneration. Researchers said not without a sense of humor, “is for the worm, this operation is very gentle.

For us, we can be more effective and more convenient of the worms were observed and studied. “Yacar professor, said the future of this technology will indirectly bring good to mankind. According to the scientists on the operating table in the worm’s findings will eventually help people overcome the human spinal rehabilitation and recovery, and many other nervous system medical problem.

Note: “NatureMethods” magazine is a world-renowned scientific methodology of the most cutting-edge forum for the publication, covering life science and related chemical in the field of technical progress demonstrated by the experiments. This issue for the academics, the first line of business providing eclectic New Vision and the new research tools, with particular emphasis on the existing work of immediate practical application.
