Cell Biology is the branch of science that studies cells at the microscopic or at the molecular level. It includes studying the cells’ physiological properties, structures, organelles, interactions with their environment, life cycle, division and apoptosis.
Yale Scientists Give The Golgi Apparatus Its Own Identity, Paving The Way For More Targeted Cancer ResearchResearchers at Yale have discovered that, contrary to previous beliefs, the Golgi apparatus is an organelle that exists independently of the larger endoplasmic reticulum and is a crucial component of cell division.
Rewind, Please: Nature Paper Shows That Cell Division Is ReversibleA scientist found a way to reverse the process of cell division.
To evade chemotherapy, some cancer cells mimic stem cellsAnti-cancer treatments often effectively shrink the size of tumors
CHECKING HOW CELLS GROW: New research dismisses a widely held assumption about cell growthResearch published today in Journal of Biology challenges an assumption about cell growth that underpins modern cellular biology.
Rare cell prevents rampant brain activityOne of the mysteries of the brain is how it avoids ending up in a state of chaos
St. Jude identifies the specific cell that causes eye cancer, disproving long-held theoryResearchers found that certain mutations enable specific cells in the retina to multiply and cause eye cancer
Researchers discover pathway to cell size, divisionOrganisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types
Location, location — Cell sizes, lives influenced by host sizeCells from the smallest to the largest of mammals often seem to be "one size fits all."
The stem cells that weren't thereMany researchers had proposed that adult stem cells develop into insulin-producing cells, called beta cells, in the pancreas.
Penn study points to new direction for pancreas cell regenerationReplacing faulty or missing cells with new insulin-making cells has been the object of diabetes research for the last decade.
The sturdier sex? — Study by Pittsburgh scientists finds female stem cells work betterFemale stem cells derived from muscle have a greater ability to regenerate skeletal muscle tissue than male cells
A new study of living cells could revolutionize the way we test drugsResearchers have made a breakthrough by detecting the electrical equivalent of a living cell's last gasp.
Massey researchers induce cell death in leukemiaResearchers presented preclinical research at the American Association of Cancer Research's annual meeting suggesting the potential of a new combination treatment for chronic lymphocytic leukemia
Cancer stem cells: know thine enemyStem cells -- popularly known as a source of biological rejuvenation -- may play harmful roles in the body
Stem cell identity in culture may strongly depend on the cellular microenvironmentIdentification, isolation and large scale culture of stem cells for potential medical applications is a major challenge in cell biology.
Asymmetry due to Perfect BalanceCell membranes are like two-dimensional fluids whose molecules are distributed evenly through lateral diffusion
Bone morphogenetic protein antagonist gremlin 1 is widely expressed by cancer-associated stromal cells and can promote tumor cell proliferationIn this work, the authors used a genomic approach to identify factors produced by cells in the microenvironment of basal cell carcinoma of the skin, one of the most common human cancers.
Deactivation of phosphatidylinositol 3,4,5-trisphosphate/Akt signaling mediates neutrophil spontaneous deathNeutrophil spontaneous death plays essential roles in neutrophil homeostasis and resolution of inflammation, whereas the underlying molecular mechanisms are still ill-defined.
Evolution of cooperation among tumor cellsExisting cancer theory suggests that individual clones of cancer cells evolve independently from one another, acquiring all of the genetic traits or hallmarks necessary to form a malignant tumor.
Hepatic Stem Cells: In Search ofIn this review, the authors discuss the different definitions and functions of hepatic progenitor cells as well as the current research efforts examining their therapeutic potential.
