CLONING TECHNOLOGY: Geron, the US-based biotechnology company specialising in embryo research has bought the Scottish cloning technology that led to Dolly the sheep. The company aims to clone patients' cells to produce specialised tissues for transplantation. Geron is issuing about US $28 million of new shares to buy Roslin Bio-Med, a private company set up in 1998 to commercialise cloning research. Ian Wilmut, the scientist in charge of Roslin's cloning programme said Scottish science would benefit through Geron's research funding.
