Guildford, UK, 28 April 2011: ReNeuron Group plc (LSE: RENE.L) notes today’s press coverage regarding an ongoing European legal case concerning the patentability of human embryonic stem cells.

A legal opinion has been given by the advocate-general of the European Court of Justice (ECJ) regarding a patent test case originally brought in Germany and ultimately referred to the ECJ.  The opinion given by the advocate-general is that patent claims involving the use of human embryonic stem cells should not be allowed. The ECJ is due to decide over the coming months whether to uphold this legal opinion in their ruling on the case.  

ReNeuron wishes to confirm that it does not utilise human embryonic stem cells in its own research and development programmes and has no plans to do so.  Consequently, ReNeuron’s technologies, development programmes and its extensive patent estate would be unaffected by any prohibition on the patenting of human embryonic stem cells in Europe.

Michael Hunt, Chief Executive Officer of ReNeuron, said:

“Whilst we support research on all stem cell types conducted under appropriate regulatory frameworks, we have always believed that the particular technologies and cell types ReNeuron works with will stand the Company in good stead in its development of patent-protected stem cell therapeutics addressing major unmet medical needs such as stroke disability.”

About ReNeuron
ReNeuron is a leading, clinical-stage stem cell business.  Its primary objective is the development of novel stem cell therapies targeting areas of significant unmet or poorly met medical need.   

ReNeuron has used its unique stem cell technologies to develop cell-based therapies for significant disease conditions where the cells can be readily administered “off-the-shelf” to any eligible patient without the need for additional immunosuppressive drug treatments.  ReNeuron’s lead candidate is its ReN001 stem cell therapy for the treatment of patients left disabled by the effects of a stroke. This therapy is currently in early clinical development.  ReNeuron’s ReN009 stem cell therapy is being developed as a treatment for peripheral arterial disease, a serious and common side-effect of diabetes. The Company is also developing stem cell therapies for other conditions such as blindness-causing diseases of the retina.

ReNeuron has also developed a range of stem cell lines for non-therapeutic applications – its ReNcell® products for use in academic and commercial research.  The Company’s ReNcell®CX and ReNcell®VM neural cell lines are marketed worldwide under license by USA-based Millipore Corporation.

ReNeuron’s shares are traded on the London AIM market under the symbol RENE.L.  Further information on ReNeuron and its products can be found at
