Plant stem cells could be fruitful source of low-cost cancer drug

26.10.2010
A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests.

Researchers have isolated and grown stem cells from a yew tree whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products.

Scientists and engineers behind the development say the drug treatment – currently used on lung, ovarian, breast, head and neck cancer – could become cheaper and more widely available. The study was carried out by the University of Edinburgh and the Unhwa Biotech company in Korea.

Currently, an extract from yew tree bark is used to industrially manufacture the compound paclitaxel. However, this process is expensive, requires supplies of mature trees, and creates environmentally damaging by-products.

Researchers claim that using stem cells – self-renewing tree cells which can be manipulated to produce large amounts of the active compound – would effectively create an abundant supply of the drug. The process would cost far less than conventional methods.

Scientists behind the project have also cultured stem cells from other plants with medical applications, indicating that the technique could be used to manufacture other important pharmaceuticals besides paclitaxel.

The study was published in Nature Biotechnology and supported by the Biotechnology and Biological Sciences Research Council and the Engineering and Physical Sciences Research Council.

Professor Gary Loake, of the University of Edinburgh's School of Biological Sciences, who led/took part in the study, said: "Plants are a rich source of medicine – around one in four drugs in use today is derived from plants. Our findings could deliver a low-cost, clean and safe way to harness the healing power of plants, potentially helping to treat cancer, and other conditions."

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
