Scientists develop artificial spider silk or help regenerative medicine

[science and technology trends of China Pharmaceutical web] Swedish research team successfully copied the spinning ability of spiders and developed artificial spider silk, one of the tough materials in nature The team said the rayon is biocompatible and may be useful for regenerative medicine Johnson pointed out that artificial spider silk may be used in the repair of vertebrae or in the cultivation of stem cells to repair damaged hearts (scientists develop artificial spider silk or help regenerate medicine picture source: Baidu picture) soft, light, and biodegradable, but harder than steel The researchers said on January 9 that they have successfully developed the artificial spider silk, one of the tough materials in nature The Swedish research team said it had successfully copied the spinning ability of spiders, using E.coli proteins and "spinning equipment" to imitate the changes in acid and alkali values when spiders produce silk, France Radio International reported on January 10, citing AFP "It's the first time that we can make spider silk without stimulating chemicals," Jan Johansson, co-author of the Research Report at the Swedish University of Agricultural Sciences, told AFP He said the large amount of protein produced by bacteria allows people to make one kilometer of bionic fiber from one liter of E.coli culture dish The team said the rayon is biocompatible and may be useful for regenerative medicine Johnson pointed out that artificial spider silk may be used in the repair of vertebrae or in the cultivation of stem cells to repair damaged hearts The invention could also be useful for the textile industry, such as making lighter and stronger body protective clothing Spiders have evolved over a long period of time Their silk is not only 30 times thinner than human hair, but also more tenacious than the man-made fiber used to make bulletproof vests Scientists have long been trying to replicate all the unique characteristics of spider silk Spider silk is essentially composed of a long string of linked protein molecules When spiders spin silk, they secrete protein liquid through narrow channels This process changes the acid-base value and increases the strength, so the protein molecules can be linked into chains However, spiders are notoriously difficult to breed, producing little spider silk and eating each other's habits (reporter Wang Lilian)
