Karen Moxon, a professor of biomedical and mechanical engineering at UC Davis, showed that a combined therapeutic regimen of drugs and physical therapy promoted cortical reorganization that bypassed a spinal cord injury, allowing paralyzed rats to walk again.
Scientists have known for 2,300 years that articular cartilage neither repairs itself nor regenerates with ease. “Cartilage, when once cut off, [does not] grow again,” observed Aristotle, the Greek philosopher and scientist, in the fourth century BC. In the last fifty years, scientists have succeeded in creating tissue that closely resembles native cartilage, but the engineered tissue lacks the tensile values required to endure the natural strains it would encounter when implanted in human joints to replace damaged cartilage.
The Heinrich lab found that single human neutrophils, a type of white blood cell, are able to accurately and reliably recognize and interact with real-world pathogens such as Salmonella bacteria and Coccidioides, the cause of Valley Fever.
A new study published by Kent Leach's group at UC Davis shows that mesenchymal stem cells (MSCs) can adapt to their environment and become resistant to low oxygen to carry out their function.
The Silva Lab is developing a new alginate hydrogel that incorporates chitosan to control the release of S1P to improve the formation of new blood vessels.

Giant lipid vesicles, topologically closed flexible compartments, subject to solute concentration gradients dissipate the available chemical energy through the osmotic movement of water, producing shape transformations driven by surface-area–volume changes.
A new virus-killing peptide springs from an unexpected source: another virus, Hepatitis C. Biomedical engineers at UC Davis and Nanyang Technological University, Singapore show how the HCV alpha-helical (AH) peptide can make holes in the types of membranes that surround viruses.
