In a randomized study, animals received injections of their own adipose stem and regenerative cells after a simulated heart attack. This approach resulted in a statistically significant reduction in perfusion defects and improved ejection fraction.
Researchers have identified key mechanisms for cell volume regulation, including water channels and organic particle efflux. Cells use these processes to manage salt concentrations and prevent osmotic disruption.
Researchers at UCLA and USUHS discovered the Ephrin-B2 receptor as the doorway for Nipah and Hendra viruses to enter cells. This finding promises to lead to better understanding of how these viruses cause disease in humans and animals, ultimately aiding in vaccine and treatment development.
A study found that gene UCHL1 is consistently low in replaceable neurons, associated with increased survival and reduced neuronal death. Researchers discovered UCHL1 levels increase when birds sing, suggesting a link to improved neuron replacement.
Researchers successfully produce spider silk fibers in insect cell cultures using genetic engineering, opening the way for commercial development. The fibers possess chemical resistance characteristics similar to those produced by spiders.
Researchers at UNC's Bowles Center discovered that new brain cells develop during alcohol abstinence, reversing damage caused by chronic alcohol dependency. The study found a twofold burst in brain cell proliferation after four-to-five weeks of abstinence.
Researcher Conrad focuses on elucidating molecular steps in embryonic animal eyes to develop new treatments for corneal transplants. His team uses mass spectrometry to analyze polysaccharides and uncover the influence of sugars on cell decisions.
In a groundbreaking study, researchers at NYU School of Medicine found that young nerve cells can rewire their developmental timeline, defying long-held assumptions about brain development. This discovery opens up new possibilities for generating neural tissue for replacement therapies.
A new study by the Society for Women's Health Research has found that spleen cells can rapidly regrow adult islet cells without embryonic stem cells. This breakthrough discovery opens up a new approach to treating Type 1 diabetes, which develops when the immune system attacks insulin-producing islet cells.
Researchers have discovered that spleen cells can regenerate insulin-secreting islets in mice with Type 1 diabetes, potentially leading to a cure. The study shows that these cells can grow from both the recipient's own cells and donor cells, opening up new approaches to diabetes treatment.
Zebrafish provide a unique window into blood cell development, allowing researchers to distinguish individual cell types and transplant genetically altered cells. The technique enables the study of cellular defects in mutant fish, which can inform human transplantation strategies.
Researchers found that specific cells in the bird's brain become 'tuned' to what the bird is learning, responding strongly to familiar songs and motifs. The study suggests that experience modifies the brain to highlight important motifs, allowing birds to recognize individual songs.
Researchers at Stanford University have witnessed the birth and growth of individual microtubules in plant cells, discovering a unique process called treadmilling. This process involves the addition and removal of protein subunits from the microtubule ends, leading to its movement across the cell.
Researchers discovered that the removal of MTase1, a viral protein, did not impact virus replication rates in tissue culture. This finding suggests that proteins essential to virus function may be more complex than previously thought, with implications for understanding virus behavior and potential applications in pest control.
Researchers at Advanced Cell Technology successfully transplanted cloned tissues into animals without rejection. The study's findings suggest that nuclear transplantation could provide a limitless supply of immune-compatible cells and organs for regenerative therapies, tackling one of the major challenges in transplantation medicine.
Researchers at Columbia University Irving Medical Center have discovered a combination of two genes that selectively kill pancreatic cancer cells in test tube experiments. The mda-7 protein and K-ras antisense DNA combination prevents tumor growth in animals, offering a potential new treatment option for this aggressive disease.
Researchers found that a fish oil-rich diet protects against colon cancer, while a corn oil-diet appears to promote it. The scientists also discovered how cancer spreads among cells in the colon, with a new understanding of cell damage varying from bottom to top within crypts.
