Illegal Use of Umbilical Cord Blood

Joint investigation team of four local police offices in Ehime, Kochi, Ibaraki and Kyoto arrested 6 persons, including a medical doctor, with suspect of violation against Regenerative Medicine Safety Preservation Law on Sunday. They are suspected to have planting umbilical cord blood without registration to the government of Japan. It was the first time for the government to make forced investigation on illegal medication related to umbilical cord blood, which was supposed to work for beauty treatment.

Umbilical cord blood is retrieved from navel string or placenta, which includes stem cell generated to blood cell. Although stem cell medication has been making in treatment for leukemia through blood cell bank with governmental license, scientific effectiveness or safety in medical treatment for cancer or beauty treatment has not been reconfirmed. Having concern on such medical treatment with high reward, the government required submission of treatment plan after legislation of Regenerative Medicine Preservation Law in 2014.

The suspects include president of an umbilical cord blood bank, broker of the blood and a medical doctor in a medical clinic in Tokyo. According to the announcement of the police team, they planted umbilical cord blood on four patients for six times without license for doing that treatment. The president of the bank also suspected as making medical treatment in Kyoto.

The planted blood had been kept in a private umbilical cord blood bank, Tsukuba Brains, which had bankrupted in 2009. The arrested president of a blood bank obtained a thousand and some hundreds of blood objects for examination in 2010 and sold 300 or 400 of them to clinics in Tokyo and Osaka. It is supposed that the president have thought the business over umbilical cord blood was profitable.

Three patients out of ten who had the treatment of planting umbilical cord blood were foreigners mainly from China. While a planting medication cost ¥3 million, the patients visited Japan in anti-aging travel tours and had the treatment. A clinic in Tokyo advertised its treatment as effective for rejuvenating cells by ten or twenty years and easing pain in cancer treatment. One clinic has earned ¥200 million with the treatment.


Study on stem cell is still in a process of verification in Japan. While umbilical cord blood is used for treatment on leukemia through public blood bank, it is expected to apply the technology to regenerative medicine such as treatment for cerebral palsy. Medical doctors are worried about negative impact of the illegal treatment on development of regenerative medicine.
