University Of Chicago Researchers Uncover First Steps In Cell-Cell Adhesion Process
For the first time, researchers describe in detail how neighboring skin cells adhere to one another to form sealed barriers.

Hide And Seek: Researchers Discover A New Way For Infectious Bacteria To Enter Cells
French scientists have learned how Listeria monocytogenes,which causes a major food-borne illness, commandeers cellular transportmachinery to invade cells and hide from the body's immune system.

Dying Cells Encourage Neighbors To Grow
Researchers have uncovered specific mechanisms by which cells that are genetically programmed to commit suicide stimulate growth in surrounding cells.

Blocking "Engulfment" Gives Dying Cells New Lease On Life
Multicellular life is a balance between cell survival and cell death.

New Method Lets Researchers Study Heart Cell Communication
Scientists at the University of North Carolina at Chapel Hill are using a new way to study how heart muscle cells communicate electrical and chemical messages.

Decision Making At The Cellular Level
It's a wonder cells make it through the day with the barrage of cues and messages they receive and transmit to direct the most basic and necessary functions of life.

A critical role for endocytosis in Wnt signaling
A necessary component of Wnt signaling occurs in a subcellular compartment distinct from the plasma membrane.

Control and maintenance of mammalian cell size
This analysis explains how cell size is maintained through a combination of interdivision time variation and cell growth rate variation.

Food For Thought: Cells Dine On Their Own Brains To Stay Fit And Trim
Eating your own brain may not sound like a sensible approach to prolonging your life, but researchers have discovered that some single-celled organisms essentially do just that to keep themselves healthy.

Cells In Retina Found To Behave Like Soap Bubbles
Soap bubbles delight children and the young at heart, but they also have been objects of scientific study for centuries.

Heart Attack In A Laboratory Dish
NWO researchers at Utrecht University have given heart muscle cells a heart attack in the laboratory.

How Cell Suicide Protects Plants From Infection
Researchers at Yale have identified a gene that regulates the major immune response in plants, programmed cell death (PCD), according to a recent report in the journal Cell.

Why Don't All Moles Progress To Melanoma?
Sometimes pigment-producing cells in moles called melanocytes start dividing abnormally to form a deadly form of skin cancer called melanoma.

Peripheral Timekeeping: Mammalian Cells Outside The Brain Have Their Own Circadian Clocks
Researchers have discovered that individual fibroblast cells contain independent, self-sustaining circadian (ca. 24 hr) clocks.

UT Southwestern Researchers Decode Filament Structures That Help Organize Signaling Molecules In Cells
Scientists have found the blueprint for how filaments assemble during the development of caveolae, a membrane system that organizes signaling molecules used by cells to communicate with each other.

Study Identifies Key Step Allowing Cells To Migrate
University of North Carolina at Chapel Hill researchers have discovered a prime regulator of the mechanism by which human cells migrate in health and in illness, a process crucial to sustaining life.

Minnesota Researchers Identify Protein That Causes Cell Nucleoli To Disassemble
Researchers at the University of Minnesota have identified the protein responsible for disassembly of donor nucleoli in the context of nuclear cloning.

How The Cell Finds Its Center
Yeast cells place their nucleus in the center of the cell, where the nucleus helps define where the cell will later divide in half.

How To Mend A Broken Heart: Zebrafish Hold Key To Regeneration
When a portion of a zebrafish's heart is removed, the dynamic interplay between a mass of stem cells that forms in the wound and the protective cell layer that covers the wound spurs the regeneration of functional new heart tissue...

Chromatin, Not Proteins, Support Chromosomes During Cell Division
When cells divide and transfer copies of genes to daughter cells, the process includes a phase where the replicated chromosomes are tightly condensed into durable packages called mitotic chromosomes.
