Stanford doctors advance in bid to turn mice stem cells into blood vessels

...stem. By creating a tissue-engineered blood vessel grown from a patient's own stem cells, this rejection could potentially be eliminated, Abilez said. "Our goal is to derive all the different cell types from the same, original cell," Abilez explained. "This would be new for an engineered tissue. We hope o...

Microscopic passengers to hitch ride on space shuttle

...m and that some microbes become more virulent when grown under conditions that simulate spaceflight, thus increasing the risk of astronauts becoming sick during flight. Whatever the mission or its duration, microbes are present where there are human beings. This experiment will focus on investigating th...

Super-sized cassava plants may help fight hunger in Africa

...ally modify cassava plants. The plants, which were grown in a greenhouse, produced roots that were an average of 2.6 times larger than those produced by regular cassava plants. "Not only did these plants produce larger roots, but the whole plant was bigger and had more leaves," Sayre said. Both the roots ...

Purdue creates new low-cost system to detect bacteria

...utes to identify harmful organisms after they have grown in a petri dish. The analysis is faster than any other methods in existence, and it's simple." The technique might be used to identify staph infections that are resistant to antibiotics. "This is an extremely dangerous infection, and you want to ...

Microscopic scaffolding offers a 'simple' solution to treating skin injuries

... of cosmetic and similar products, using materials grown in the laboratory that closely resemble natural skin. "Ultimately, we can envisage treatment of burns victims and the undertaking of reconstructive surgery using the scaffold and the patient's own skin to produce bespoke skin for that patient," sa...

Technique speeds up detecting, treating wound bacteria

...lso useful in detecting flora that can't easily be grown in culture because no one's been able to determine just what the bacteria like in the way of nutrients and environmental conditions. The earlier the lab staff has answers, the earlier the correct treatment can begin. Initial treatment is necessaril...

Single cell amoeba increases MRSA numbers 1000- fold

...re more invasive than the same bacteria which have grown freely. Replication within amoebae may have the same effect on MRSA. Amoebae, as cysts, are often dispersed by air currents, providing another means of spreading any trapped bacteria. "We need more research into the role of amoeba in the spread of ...
