About FullStem

FullStem has developed Achieva-CS^*1: a high-density, large-scale stem cell culture device that employs a proprietary method for high-density, three-dimensional, large-scale culture and recovery.

The company’s concept here is to have a device that anyone can use safely and easily, and the company is aiming now to commercialize its technology for use in large-scale stem cell culture.

Achieva-CS uses special nonwovens as scaffolding for stem cell culture to enable a more compact, high-density culture area. This then facilitates the large-scale culture of stem cells under conditions that are inexpensive while being close to those of an in vivo environment. In addition to selling Achieva-CS, FullStem is working to use this technology to develop large-scale culture technology for medical applications, as well as sell related products.
