A novel cellular process to engulf nano-sized materials

Nanometers are one billionth of a meter, a metric typically used to measure molecules and scientific building blocks not visible to the human eye. Materials of tens and/or several hundred nanometers in diameter have unique ...

New nanotechnology could aid stem cell transplantation research

Nanotechnology developed at Rutgers University-New Brunswick could boost research on stem cell transplantation, which may help people with Alzheimer's disease, Parkinson's disease, other neurodegenerative diseases and central ...

Controlling the shape-shifting skeletons of cells

You know you have a skeleton, but did you know that your cells have skeletons, too? Cellular skeletons, or cytoskeletons, are shapeshifting networks of tiny protein filaments, enabling cells to propel themselves, carry cargo, ...

Performing chemistry in floating droplets

Could chemists be ready to ditch the venerable test tube, the very symbol of chemistry in the minds of many people? Maybe not quite yet, but Caltech's Jack Beauchamp is working on it.

Amoeba builds barriers for protection against bacteria

In some respects, animals and amoebae are not that different. For instance, both are at risk of potentially deadly attacks by bacteria and have evolved ways to prevent them. Researchers at Baylor College of Medicine report ...

Sophisticated molecular machines in action

Almost all living organisms from bacteria to humans have gate-like protein complexes in their cell membranes that get rid of unwanted or life-threatening molecules. This is not always advantageous, since in the case of bacteria ...

Do plant cells hold the roadmap for surviving climate change?

Do plant scientists hold the key to saving vulnerable populations in a changing climate? How should plant researchers prepare to deploy their knowledge to maintain food security in the future—as well as to promote renewable ...

Cell biology

Cell biology (formerly cytology, from the Greek kytos, "container") is an academic discipline that studies cells – their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. This is done both on a microscopic and molecular level. Cell biology research encompasses both the great diversity of single-celled organisms like bacteria and protozoa, as well as the many specialized cells in multicellular organisms like humans.

Knowing the components of cells and how cells work is fundamental to all biological sciences. Appreciating the similarities and differences between cell types is particularly important to the fields of cell and molecular biology as well as to biomedical fields such as cancer research and developmental biology. These fundamental similarities and differences provide a unifying theme, sometimes allowing the principles learned from studying one cell type to be extrapolated and generalized to other cell types. Hence, research in cell biology is closely related to genetics, biochemistry, molecular biology and developmental biology.
