InvivoSciences, WUSTL to construct artificial tissue models for heart failure

The National Institutes of Health has awarded more than $2 million to a team of scientists from Washington University in St. Louis and InvivoSciences, a biotechnology startup with WUSTL roots, to construct artificial tissue models that will allow the rapid testing of new drugs for heart failure.

Next generation predictive 3D cell toxicity assays to be developed by Medicyte GmbH and Reinnervate Ltd

Two market leading companies in the field of cell based assays and predictive toxicology today announced a new product collaboration. Medicyte (inventors of the upcyte® technology) and Reinnervate (market leaders in the growing field of 3D cell culture) said they will work together to combine their upcyte® and Alvetex®Scaffold technologies to bring next generation cell bases assays to the biopharma and academic research markets.

Effect of spaceflight on C. elegans could help it to live longer

The effect of spaceflight on a microscopic worm - Caenorhabditis elegans (C. elegans) - could help it to live longer.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

New toxicology testing method requires lesser number of fish

A new way of testing the safety of natural and synthetic chemicals has been developed by scientists with funding from the Biotechnology and Biological Sciences Research Council (BBSRC). Their research, published today in the journal Ecotoxicology, could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.

New laboratory model for Huntington's disease

Cedars-Sinai scientists have joined with expert colleagues around the globe in using stem cells to develop a laboratory model for Huntington's disease, allowing researchers for the first time to test directly on human cells potential treatments for this fatal, inherited disorder.

New photoactive compound eradicates 'Iraqibacter' from wounds and skin infections

Researchers at the University of California, Santa Cruz, have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. The UCSC team developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material that could be applied as a sprayable powder.

Bioengineers develop first structure to grow small human blood vessels

Mice and monkeys don't develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates. University of Washington bioengineers have developed the first structure to grow small human blood vessels, creating a 3-D test bed that offers a better way to study disease, test drugs and perhaps someday grow human tissues for transplant.

New system measures strength of communication between muscle cells and motor neurons

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish.

Experts identify new gene that could help development of human fertility treatments

Experts from Durham University have identified a new gene that could help the development of fertility treatments in humans in the future.

Irreversible Electroporation can more effectively kill cancer cells with BNNTs

A new study has shown that adding boron-nitride nanotubes to the surface of cancer cells can double the effectiveness of Irreversible Electroporation, a minimally invasive treatment for soft tissue tumors in the liver, lung, prostate, head and neck, kidney and pancreas.

Helpful roles of rank, toxic substances

Usually, we think of mold, feces, nitric oxide, hydrogen sulfide and rat poison as rank, toxic or both. But scientists funded by the National Institutes of Health are learning more about the helpful roles these substances can play.

Cell graphs link structure of human tissue to corresponding biological function

Computer scientists and biologists in the Data Science Research Center at Rensselaer Polytechnic Institute have developed a rare collaboration between the two very different fields to pick apart a fundamental roadblock to progress in modern medicine. Their unique partnership has uncovered a new computational model called "cell graphs" that links the structure of human tissue to its corresponding biological function.

Studies use three genes to reprogram fibroblasts into myocytes

The latest research developments to reprogram scar tissue resulting from myocardial infarction (MI) into viable heart muscle cells, were presented at the Frontiers in CardioVascular Biology (FCVB) 2012 meeting, held 30 March to 1 April at the South Kensington Campus of Imperial College in London.

Cancer cells grow and proliferate more robustly when exposed to human cells

New research from the Technion-Israel Institute of Technology Rappaport Faculty of Medicine and Research Institute and the Rambam Medical Center may lead to the development of new methods for controlling the growth of cancer, and perhaps lead to treatments that will transform cancer from a lethal disease to a chronic, manageable one, similar to AIDS.

Scientists artificially derive brain stem cells from connective tissue of mice

These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells.

n3D releases new 24-well Bio-Assembler

Only days after Rainbow BioSciences closed a deal to acquire an equity interest in Nano3D Biosciences, n3D announced the release of its groundbreaking new 24-well Bio-Assembler.

Planarian flatworms reveal new insights into stem cell biology

Devising a novel method to identify potential genetic regulators in planarian stem cells, Whitehead Institute scientists have determined which of those genes affect the two main functions of stem cells. Three of the genes are particularly intriguing because they code for proteins similar to those known to regulate mammalian embryonic stem cells. Such genetic similarity makes planarians an even more attractive model for studying stem cell biology in vivo.

Scientists create first 3-D living tissue model of glioma

Brown University scientists have created the first three-dimensional living tissue model, complete with surrounding blood vessels, to analyze the effectiveness of therapeutics to combat brain tumors. The 3-D model gives medical researchers more and better information than Petri dish tissue cultures.
