In cytology or cell biology, cell adhesion is a process by which cells attach to neighbors through specialized structures on their surface. Cell adhesion can occur either through direct contact … Continue Reading Previously unknown human cell structure identified.
The nucleolus is a crucial membrane-less structure or organelle that takes up about 25% of the nucleus of a mammalian cell. The largest membrane-less organelle, the nucleolus has been compared … Continue Reading Protein ‘glue’ which holds biomolecules within the nucleolus, identified.
Age is the largest risk factor for numerous pathologies, ranging from neurodegeneration to cancer. These pathologies likely arise from a loss of tissue homeostasis driven by one or more basic … Continue Reading New role for mitochondria identified in cellular senescence and aging.
Neural stem cells generate new neurons throughout life in the mammalian brain. Neural stem cells are self-renewing, multipotent cells that generate the main phenotype of the nervous system. Stem cells … Continue Reading Researchers identify neuroprotective mechanism against stem cell aging.
Structural proteins perform much like their name suggests, they maintain cell shape and make up connective tissues like cartilage and bone. Telling a cell biologist that a structural protein is … Continue Reading Transcription factor doubling as a structural protein identified in world’s first.
Study begins to map the epigenetics of brain plasticity, the switch which changes neuronal function.
Scientists at the Salk Institute have discovered that the role of neurons, which are responsible for specific tasks in the brain, is much more flexible than previously believed. By studying … Continue Reading Study begins to map the epigenetics of brain plasticity, the switch which changes neuronal function.
Sensory hair cell loss is the major cause of hearing loss and balance disorders. The postnatal mammalian inner ear harbors progenitor cells which have the potential for hair cell regeneration … Continue Reading Researchers regenerate inner ear hair cells via the Notch pathway to restore hearing.
