They induce stem cells to the affected area to take advantage of iron powder and a magnet.

To repair the damaged cartilage and fractures by age or accident, 27, of regenerative medicine research using the magnet was adopted to promote research and development project of the Ministry of Education, Culture, Sports, Science. Hiroshima studies, aiming to start of clinical research in around three years. If it is practical, is expected to be less of a burden to the patient treatment is more efficient than a conventional well.

Was adopted, research professor of Ochi et al. (Orthopedics). But how to repair by changing into cartilage and bone near the affected area by injecting stem cells, bone marrow cells were cultured from the patient's stem cells to mix iron powder characteristics. In order to induce the stem cells to the affected area a strong magnet from outside, there is no need for surgery, unlike conventional treatments, such as artificial joints.

Prof. Ochi, ensure safety and efficacy in experiments using pig ever. Business of the Ministry of Education to evaluate in more detail, such as the safety of the cells mixed with iron powder. I'm talking with Professor Ochi "I want to start a clinical research in around three years later." I hope the diseased stem cells induced by utilizing magnets and iron powder, and put into practical use.



加齢や事故によって損傷した軟骨や骨折を修復するため、磁石を利用した再生医療の研究が２７日、文部科学省の研究開発推進事業に採択された。広島大の研究で、３年後をめどに臨床研究の開始を目指す。実用化されれば、従来より効率がよく患者への負担が少ない治療法として期待される。
　採択されたのは、越智教授（整形外科）らの研究。患者の骨髄細胞から培養した幹細胞を、患部の近くに注射して軟骨や骨に変化させて修復する方法だが、幹細胞に鉄粉を混ぜるのが特徴。体外から強力な磁石で幹細胞を患部に誘導するため、人工関節など従来の治療法と違い手術の必要がない。
　越智教授らは、これまでブタを使った実験で有効性や安全性を確認。文科省の事業では鉄粉を混ぜた細胞の安全性などをさらに詳しく評価する。越智教授は「３年後をめどに臨床研究を始めたい」と話している。鉄粉と磁石を活用して幹細胞を患部に誘導、実用化するといいですね。
