When you have seriously damaged bones you want to regrow them quickly, but you also have to carefully manage that growth to produce the right shape. A gel has been created by Rice University researchers that makes it easier to produce only the bone tissue a patient needs. (Video)
New low-intensity pulsed ultrasound device helps regrow teeth.
Researchers at the University of Alberta in Canada have developed a low-intensity pulsed ultrasound (LIPUS) technology that they hope will ultimately be able to re-grow lost or severely damaged teeth from the root, eliminating the need for pricey prosthetics and painful procedures.
The discovery could lead to developing a drug that can trigger regrowth of damaged nerves.
Spinal cord injuries are currently irreparable. Most people who suffer from such an injury never fully recover, and many end up with partial or even full paralysis. Although we’ve made great strides in understanding how spinal injuries damage nerves and how we might fix the spinal cord in the future, and even how those patients can cope in the meantime, we still don’t know how to repair the nerves themselves when such an injury occurs. However, scientists at Imperial College London have recently discovered a mechanism that allows them to repair, and even regenerate, nerves in the central nervous system after a spinal cord injury.
Researchers worked with mice and found that if a portion of the heart was removed within the first week of life, the heart grew back completely.
An adult zebra fish can regenerate a damaged heart with no scar formation. This remarkable phenomenon has been seen in other fish and amphibians as well, but never before in a mammal.
Scientists at the University of California, Los Angeles (UCLA) and the Veterans Administration (VA) did discover a chemical compound that caused hair regrowth in mice with alopecia, but they were testing the compound on the mouse digestive system.
