Tissue engineering has long held promise for building new organs to replace damaged livers, blood vessels and other body parts. However, one major obstacle is getting cells grown in a lab dish to form 3-D shapes instead of flat layers.
It's a bit of a challenge. But, imagine a microscopic jet vacuum cleaner, the size of a pen nib that hovers over cell surfaces without ever touching them. Then imagine that the soap in the cleaning solution is replaced with various molecules that can be selectively delivered to the cells. This gives you a sense of a new device that researchers believe will serve as a powerful tool to study the behaviour of living cells and a range of crucial cellular processes, from cancer cell formation to how neurons align themselves in the developing brain.
Eve Marder, PhD, a professor of neuroscience at Brandeis University, is the recipient of the 2013 Neuroscience Prize of The Gruber Foundation. Marder is being honored with this prestigious international award for her pioneering contributions to the understanding of neural circuits, particularly how the properties and dynamics of neural circuits give rise to specific behaviors.
In a small clinical study, researchers administered a new method for treating chronic wounds using a novel ultrasound applicator that can be worn like a band-aid. The applicator delivers low-frequency, low-intensity ultrasound directly to wounds, and was found to significantly accelerate healing in five patients with venous ulcers.
