Two studies in the Jan. 27, 2006 Cell have yielded evidence that could prove a boon for stem cell therapies aimed at patients with Parkinsons disease and those with compromised immune systems due to intensive cancer therapy or autoimmune disease, according to researchers. The basic findings in mice revealed critical factors that determine the fate of one type of nerve cell progenitor and that set bone marrow stem cells into action.
Researchers at the Karolinska Institutet in Sweden discovered a "master determinant" that turns embryonic stem cells into bona fide dopamine neurons, brain cells that degenerate in those with Parkinsons disease. The findings hold promise for the future of cell replacement therapy for the debilitating and incurable disease characterized by tremors, said study authors Thomas Perlmann and Johan Ericson. The results also underscore the general importance of a thorough understanding of development for producing authentic cells of a desired type from stem cells.
"The use of cell replacement therapy in the treatment of Parkinsons disease is fraught with many problems," Perlmann said. "However, clinical trials have provided important proof of principle that transplantation of dopamine neurons might work in patients."

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
