Researchers have devised a new method for the cultivation of skin cells (keratinocytes) on new support materials, which can be transferred to the site of the skin defect. The support material is a hydrophilic polymer carrying specific saccharide molecules for the cultivation of keratinocytes.

Studies have shown that the new polymer-based system holds specific advantages over similar approaches, in terms of mechanical and swelling characteristics. The main structural advantage of this procedure lies in the mode of bonding of the saccharide molecules, which essentially leaves the mechanical properties of the polymer carrier unaltered. Furthermore, the cultivation of the cellular populations can be realised without the use of feeder cells, thus simplifying the process.

A series of patents have been filed for, covering the new technology. The researchers are now in a position to seek a licensing agreement with a suitable partner in order to further explore the potential of this approach.
