An upcoming genetics investigation into the symbiotic association between soil fungi and feedstock plants for bioenergy production could lead to more efficient uptake of nutrients, which would help limit the need for expensive and polluting fertilizers.
By understanding the secret of how lizards regenerate their tails, researchers may be able to develop ways to stimulate the regeneration of limbs in humans. Now, a team of researchers is one step closer to solving that mystery.
In a new study, a thermosensitive collagen hydrogel remained as a liquid when kept at temperatures below 10C and gelled when the temperature was increased to 37C in an incubator for 30 minutes, which was used as an extracellular matrix and combined with bone marrow mesenchymal stem cells to construct tissue-engineered peripheral nerve composites in vitro.
In a boon to stem cell research and regenerative medicine, scientists have created a computer algorithm called CellNet as a 'roadmap' for cell and tissue engineering, to ensure that cells engineered in the lab have the same favorable properties as cells in our own bodies.
A new technique has demonstrated for the first time that the size of molecules penetrating the blood-brain barrier can be controlled using acoustic pressure - the pressure of an ultrasound beam - to let specific molecules through.
Scientists discovered that living cell migration is regulated by the engagement of a force transmitter composed of vinculin and talin, two types of cytoskeletal protein. The researchers showed that force-dependent vinculin binding to talin plays a critical role in mechanically connecting the actin cytoskeleton to the extracellular substrate to contribute towards cell migration.
Deep within most tumors lie areas that remain untouched by chemotherapy and radiation. These troublesome spots lack the blood and oxygen needed for traditional therapies to work, but provide the perfect target for a new cancer treatment using bacteria that thrive in oxygen-poor conditions. Now, researchers have shown that injections of a weakened version of one such anaerobic bacteria can shrink tumors in rats, pet dogs, and a human patient.
