University of Manchester makes made-to-measure skin and bones a reality using inkjet printers

... of cell to be printed at once, which opens up the possibility ofbeing able to create bone grafts."Using conventional methods, you are only able to grow tissues whichare a few millimetres thick, which is fine for growing artificial skin,but if you wanted to grow cartilage, for instance, it would beimpossible," P...

Growth in the sea comes down to a struggle for iron

...ly. Wells and his colleagues will be studying the possibility that small variations in iron throughout the world's oceans may have important ecological consequences as well. Their results will contribute to the diverse oceanographic understanding needed to determine whether or not adding iron to ocean waters is...

Current human embryonic stem cell lines contaminated UCSD/Salk team finds

...t they haverecently produced such a mouse. Another possibility being attempted bygroups in other parts of the world is to use human embryo-derivedconnective tissue cells as the feeder layer in the culture.A further solution might be a short-term culture in heat-inactivatedserum from the actual patient who is goi...

Bacteria collection sheds light on urinary tract infections

...ng the infections is resistant to antibiotics. The possibility that these multidrug-resistant bacteria could have an animal origin has major public health implications because of the practice of administering subtherapeutic doses of antibiotics as growth promoters in animals. E.coli is common bacteria found in ...

Breakthrough Microarray-based Technology for the Study of Cancer

...ntrons and exons. This advancement, along with the possibility itprovides to correlate genomic copy alterations with mRNA abundance andprotein abundance, is going to incite a huge body of experimentationand publication among the cancer research community."In the past, comparative genomic hybridization was perfor...

Mouse brain tumors mimic those in human genetic disorder

...f tumors," Gutmann says. "These findings raise the possibility thattargeted therapies for NF1 brain tumors may involve agents that preventthe supply of growth promoting factors provided by new blood vesselsand microglia."Next, the researchers used the mouse model to investigate a clinicalconcern. Physicians rely...

Scientists rid stem cell culture of key animal cells

.... Although the new work "dramatically reduces the possibility of contamination" from animal pathogens, Xu warns that the continued use of serum replacement and Matrigel means that contamination remains a concern. The ultimate goal, he says, would be to culture stem cells in media completely free of any animal p...

Open microfluidic and nanofluidic systems

...gent volumes, much shorter reaction times, and the possibility of massive parallel processing. In general, this should lead to increased throughput and, thus, to reduced cost of (bio)chemical analysis. In addition, such integrated labs-on-a-chip have many potential applications in biomedicine and bioengineering....

UCSD discovery may help extend life of natural pesticide

...to vertebrates. This work furthermore opens up the possibility of using Bt toxins against roundworms that parasitize humans. "These parasites infect nearly one-third of the human population and pose a significant health problem in developing countries," said Aroian. "Perhaps one-day vertebrate-safe Bt toxins co...

Influenza vaccine uses insect cells to speed development

...pment time, another drawback to this method is the possibility that an avian influenza virus would be lethal to embryos in the eggs. The vaccine strategy pursued by Protein Sciences, known commercially as FluBlok, does not rely on whole vaccine virus. It uses a purified concentration of a key molecule on the su...
