Researchers are exploring the potential of lysophosphatidic acid (LPA) and gelatin to promote blood vessel formation and heal wounds. The study aims to determine how LPA interacts with specific proteins, such as Hic-5, to enhance or inhibit migration.
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.
Researchers discovered that a cell death protein, IAP, plays a surprising role in restoring cellular movement in fruit fly ovaries. By studying engineered flies with dysfunctional Rac protein, they found that IAP can compensate for the lack of functional Rac, allowing cells to migrate properly and restore fertility.
Research found that hepatocyte growth factor (HGF) coordinates cellular behaviors for tubule development through sequential regulation of ERK and matrix metalloproteases. The study used MDCK cells to examine molecular events during tubulogenesis, revealing distinct regulatory subprograms acting at different times.
Research finds that passive smoking hinders healing by changing the arrangement of fibroblast cells' cytoskeleton, making them less mobile and more prone to abnormal scarring. This can lead to slower wound closure rates in smokers compared to non-smokers.
Researchers at Thomas Jefferson University have found that statins interfere with a biochemical pathway crucial for germ cell migration in embryonic zebrafish. This understanding may lead to insights into disease processes, including cancer, as abnormal germ cell migration can contribute to deadly cancer spread.
Researchers discovered glycosylation enhances MIG-17 action, guiding gonad cell migration; deficiency causes abnormal gonad development. Glycosylation defects may also impact ADAM-family protein functions, leading to human diseases.
Researchers found that stem cells from human peripheral blood improved motor and cognitive performance in transplanted rats, with reduced brain damage in the affected areas. The study suggests that using these stem cells may be a viable treatment option for stroke patients.
Researchers found endostatin treatment reduced invasive head and neck cancer cells by half and their migratory capabilities by one-quarter. The study suggests an implanted drug delivery system could provide sustained therapeutic drug levels directly to tumors.
Researchers at Rice University have developed a new chemical process, pyrolytic fluorination, that yields short carbon nanotubes with predictable lengths. The technique involves attaching fluorine atoms to the nanotubes and then heating them to cut the tubes into segments ranging from 20-300 nanometers.
Scientists have identified a new cell type, VENT cells, that migrate to the developing inner ear and mix with epidermal cells, contributing to the formation of complex tissues. The discovery, made by Dr. Paul Sohal, could explain how single cells give rise to distinct systems.
A researcher has found a new cell type, VENT cells, that can give rise to all four major types of human tissue. This discovery challenges the existing understanding of human development and opens up new avenues for research into diseases such as Hirschsprung's disease and esophageal reflux disease.

This system, discovered by Martin Gorovsky and Kazufumi Mochizuki, helps regulate the cell's genome and prevent disastrous effects from genetic mutations.
Human neural stem cells transplanted into normal mice and reeler mice showed symmetrical migration in the former but failed to migrate in the latter. This suggests that protein reelin plays a critical role in directing stem cell migration, potentially underlying schizophrenia's distorted perception and thinking.
