IP Group plc (LSE: IPO) ("IP Group"), the developer of intellectual property based businesses, is pleased to note that Tissue Regenix Group plc ("Tissue Regenix" or "the Company"), a medical technology company that is held within the IP Group portfolio and a spin-out company from the University of Leeds, has today joined AIM via a reverse takeover of Oxeco plc (AIM: OXE) ("Oxeco") (the "Reversal").

First day dealings on AIM of Ordinary Shares ("Ordinary Shares") in Tissue Regenix commence today. Concurrent with the Reversal, Tissue Regenix has completed a placing raising proceeds (before expenses) of £4.5 million.

Tissue Regenix (AIM: TRX) is a medical technology company focused on the development and commercialisation of acellular tissue replacement products to address the chronic global shortfalls in donor tissue availability. Tissue Regenix uses its proprietary technology platform, dCELL®, to remove cells and other components from human and animal tissue allowing them to be used without anti-rejection drugs to replace worn out or diseased body parts.

The three priority markets for the application of the technology are vascular, cardiac and orthopaedics. Tissue Regenix's lead product is the dCELL® Vascular Patch, intended to be permanently implanted into the human body for vascular repair. The company intends to start marketing the dCELL® Vascular Patch in Europe during the second half of 2010. The next product on which Tissue Regenix intends to focus is the dCELL® Meniscus, for the repair of damaged knee meniscus.

IP Group is beneficially interested in 71,703,123 Ordinary Shares in Tissue Regenix (worth £3.6 million at the placing price of 5 pence per share), representing 15.4% of Tissue Regenix's enlarged issued share capital. The Reversal will result in a fair value gain to IP Group of £1.4 million.

Tissue Regenix is the fourteenth of IP Group's portfolio companies to have listed on either AIM or PLUS Markets and is the second IP Group portfolio company to have achieved a listing this year following Ilika plc's flotation in May.
