Are there studies that document this success for the different disease patterns?
Matthiesen: We conduct our own studies and there are already several publications on this subject. The European clinical study ADIPOA, in which the University Hospital Würzburg was a part of and new data from the Czech Republic and Poland show the positive use of stem cells for knee and hip joint diseases. In a treatment study by the Department of Plastic Surgery at the Sana Clinical Center Hameln-Pyrmont, Dr. Christian Herold reports that patients had adipose tissue injected into the saddle joint of the thumb - with great success. This was still unimaginable a few short years ago.
The newly developed device you are currently collaborating on with Prof. Hermann Seitz of the University of Rostock is designed to work with water jet technology. How does this work and what else can the device do?
Matthiesen: We develop devices for the intraoperative retrieval of vital adipose and stem cells. In the process, multipotent stem cells in adipose tissue are being isolated and concentrated. The foundation for this device development is the use of already authorized systems for water-jet assisted liposuction. The stainless steel needle used in this method directs a fan-shaped jet into the tissue to gently loosen it. Unharmed adipose cells can subsequently be extracted. However, the retrieved cell clusters must not be bigger than one millimeter, otherwise they may necrotize after transplantation. This is why the device also ensures that size is not exceeded.
