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: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
