The development of a new culture.

Five days , Keio University School of Medicine and Ajinomoto has announced that it has developed a new culture induced pluripotent stem cells of human (iPS cells) . Compared to the expensive culture of foreign-made that are currently used , the growth rate of iPS cells is high , the production cost is low . Ajinomoto is aiming the launch of fiscal 2016 .
because of their ability to turn into a variety of cells, such as nerve and muscle , in addition to be used for experiments in the development of pharmaceutical products , the realization of regenerative medicine to port incurable diseases are expected to be future iPS cells . However , because it would change into other types of cells If you do not pay close attention , expensive leased culture is being used .
Because iPS cells require large amounts of regenerative medicine in the realization of the heart , Fujita , et al Lecturer and Professor Fukuda of Keio Univ School of Medicine , joint research and chief scientist Okamoto et al Ajinomoto . For sugar and amino acid nutrients , such as vitamins , to narrow down the amount and components necessary for culture, which balanced the cost down and improve the growth performance . It is iPs cells of the feeling that shadow is thinner in front of the STAP cell but I hope that the release of the culture of the high growth rate me spurred clinical trials at low cost .




慶応大医学部と味の素は5日、ヒトの人工多能性幹細胞（iPS細胞）の培養液を新たに開発したと発表した。現在使われている外国製の高価な培養液に比べ、iPS細胞の増殖率が高く、製造コストが安いという。味の素は2016年度の発売を目指している。
　iPS細胞は神経や筋肉などのさまざまな細胞に変わる能力があるため、医薬品を開発する際の実験に使われるほか、将来は難病患者に移植する再生医療の実現が期待されている。しかし、細心の注意を払わないと他の種類の細胞に変わってしまうため、高価な専用培養液が使われている。　
　慶大医学部の福田教授や藤田特任講師らは、心臓の再生医療実現には大量のiPS細胞が必要となるため、味の素の岡元主任研究員らと共同研究。アミノ酸や糖類、ビタミンなどの栄養素について、培養に必要な成分と量を絞り込み、増殖性能の向上とコストダウンを両立させた。STAP細胞の前に影が薄くなっている感じのiPs細胞ですが安価で高増殖率の培養液の発売が臨床治験に拍車をかけてくれることを期待します。
