The UK Patent Office has granted Stem Cell Sciences  with a patent covering its new range of stem cell culture media. The new Culticell iSTEM range uses the inhibitor-based technology discovered by Prof Austin Smith.

The culture media covered by this patent contain the key combination of two or three types of enzyme inhibitor.  Prof Smith discovered that by inhibiting certain key enzymes in specific combinations, pluripotent (or embryonic) mouse stem cells could be grown reliably without feeder cells, growth factors, leukaemia inhibitory factor or serum.

The UK patent, number GB2436737B covers any use of this media, and also the use of the media for culturing stem cells, especially pluripotent stem cells.  This gives the Stem Cell Sciences the exclusive right to market cell culture media containing these inhibitor combinations.
