Heart patches and functioning kidney units cloned in cows
Advanced Cell Technology, Inc. (ACT) reported today that nuclear transplantation can be used to generate functional immune-compatible tissues. The research, which will appear in the July issue (cover story) of Nature Biotechnology, by ACT and its collaborators, provides the first experimental evidence that it may be possible to use cloning to generate medically important tissues and eliminate tissue rejection. Heart patches and miniature kidneys engineered from cloned cells were successfully tested in a large-animal model, the cow, which has a sophisticated immune system similar to that of humans.
"These results bode well for the future of human therapeutic cloning," said Robert Lanza, Vice President of Medical & Scientific Development at ACT, and lead author of the study. "Cloning could theoretically provide a limitless supply of cells and organs for any type of regenerative therapy. Before now, therapeutic cloning as a means of preventing rejection was criticized by some as being purely theoretical – just an idea. This study furnishes the first scientific evidence that cloned tissues can be transplanted back into animals without being destroyed by the bodys immune system. The use in medicine to generate immune-compatible cells using cloning would overcome one of the major scientific challenges in transplantation medicine - namely, the problem of organ and tissue rejection."
The goal of nuclear transplantation is to clone genetically matched cells and organs for transplantation into patients suffering from a wide range of disorders that result from tissue loss or dysfunction. In addition to patients with heart, lung, liver and/or kidney disease, millions more suffer from diabetes, arthritis, AIDS, strokes, cancer and other diseases that may one day be treatable using this technology. It has been estimated that by the year 2010 over 2 million patients will suffer from end-stage kidney disease alone, at an aggregate cost of over $1 trillion dollars during the coming decade.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
