Science Education: Cell Biology
Understanding the structure and function of cells and their many parts, in health and in disease—that's cell biology. Studies in cell biology focus on questions like:
- How do cells move, communicate, divide and ultimately die?
- How are cellular components made and maintained?
- What tools do we need to study cells up close and in real time?

Nobel Prize for Powerful Microscopy Technology
An NIGMS grantee is honored with a Nobel Prize for his role in developing super-resolution fluorescence microscopy, which lets researchers see and track individual molecules in living organisms in real time.
Recreating cheese rind microbial communities in the lab could answer fundamental questions about the ecology of other microbial communities, including infection-causing biofilms.
Restoring the Function of an Immune Receptor Involved in Crohn's Disease
A protective protein restores the function of an immune receptor associated with Crohn's and other inflammatory diseases.
Meet mitochondria: cellular compartments that are best known as the powerhouses that convert energy from the food we eat into energy that runs a range of biological processes.
The Fireworks Inside Us All
Here are just a few glimpses into cells captured by scientists in the course of their NIH-funded research.
Bleach vs. Bacteria
Details about how bleach kills-and how bacteria can survive the attack-may lead to the development of new drugs.
Chemist Marc Zimmer studies protein molecules that make animals glow in the dark—and help scientists study their cells.
Mastering Stem Cells
Researcher Peggy Goodell pursues the properties and uses of stem cells.
The Forces That Bind
Engineer Andrés García studies cell stickiness to create new biomaterials that can heal bones and other body tissues.
Cool Video: How a Microtubule Builds and Deconstructs
In a process critical for many biological activities, tubulin proteins snap into place to build a microtubule, part of the cell's skeleton, which then falls to pieces from its top end.
Cool Video: How Bee Venom Toxin Kills Cells
A new video that shows how a toxin destroys an animal or bacterial cell might help scientists design new drugs to combat bacterial infections.
Cool Video: How Cilia Do the Wave
Thin, hairlike biological structures called cilia are tiny but mighty. Working together, cilia play essential roles in human health, such as sweeping debris from the lungs.
Cool Image: Of Surfaces and Stem Cells
The green threads shown here are neurons that have just formed from unspecialized cells called stem cells.
Cool Image: Training Cells to Devour Dying Neighbors
A healthy cell has engulfed a number of dying cells just as a predator might ingest wounded or dying prey.
Cool Image: Outsourcing Cellular Housekeeping
Neurons in the mouse optic nerve pass some of their worn out mitochondria to neighboring brain cells for recycling.
