Learn how cells work together in tissues, organs, and organ systems. In 1665, Robert Hooke coined the term cell to describe the structures he could see in cork with some of the first microscopes. Since then, …
Phys.org: Zapping stem cells could boost growth of new tissues and organs
Scientists in Melbourne have discovered how tiny electrical pulses can steer stem cells as they grow, opening the door to new improved ways of creating new tissues, organs, nerves and bones. Dr. Amy ...
Medical Xpress: New tracking tool reveals how T cells adapt in different organs
Our immune system relies on T cells to fight infections. But T cells don't just show up and react—first, they train, get a game plan, and coordinate their defenses in lymphoid organs. Researchers have ...

EurekAlert!: Construction of three-dimensional atlases encompassing all cells across whole organs and the whole body
Construction of three-dimensional atlases encompassing all cells across whole organs and the whole body
A new study from scientists at the University of North Carolina at Chapel Hill reveals that the cells shaping our organs may be far more mobile and coordinated than once believed. Using fruit flies as ...
New Scientist: The secret signals our organs send to repair tissues and slow ageing
The secret signals our organs send to repair tissues and slow ageing
Using their novel Freeform Reversible Embedding of Suspended Hydrogels (FRESH) 3D bioprinting technique, which allows for the printing of soft living cells and tissues, Carnegie Mellon's Feinberg lab ...
Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a …
Cell theory, developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and …
Cells consist of a variety of internal and external structures that perform specialized functions necessary for survival and reproduction. These components vary depending on whether the …
Some cells are organisms unto themselves; others are part of multicellular organisms. All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates...
Beneath the skin, beyond the bones, and within every organ of every living creature lies an astonishing world of microscopic structures—the cells. They are the smallest units of life, the …
Take your cellular knowledge to the next level! From organelles to membrane transport, this unit covers the facts you need to know about cells - the tiny building blocks of life.
Cells are the basic building blocks of all living things. The human body is made of trillions of cells that carry out specialized functions.
Cells are incredibly diverse in their morphology and function. They can range from the minuscule Mycoplasmas, the smallest known cells, to complex multicellular organisms like humans, …
Real Cell Gallery The images in this gallery show real cells under the microscope. Do they look like cell diagrams you’ve seen? Probably not! Most cell diagrams, whether in your textbook or online, are …
All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.
From organelles to membrane transport, this unit covers the facts you need to know about cells - the tiny building blocks of life. Explore the structures and functions of major eukaryotic cell organelles.
All cells can be sorted into one of two groups: eukaryotes and prokaryotes. A eukaryote has a nucleus and membrane-bound organelles, while a prokaryote does not. Plants and animals are made of …
Cells help in the formation of the structure of an organism. A cell is a membrane-bound unit that has other cell organelles, which perform different functions. In eukaryotic cells, the nucleus …
Medical Xpress: Organs-on-chips provide insights into molecular mechanisms of disease, facilitate design of newer treatment strategies
Organs-on-chips (OoCs) represent a revolutionary advancement in the study of human physiology and disease, offering an in vitro microphysiological environment that mimics the functions of human organs ...

The New York Times: Nobel Prize in Physiology or Medicine Is Awarded for Work on Immune Systems
Nobel Prize in Physiology or Medicine Is Awarded for Work on Immune Systems
Organoids are 3D cultures that mimic organ structure and function, derived from embryonic, adult, or iPSCs cells.
Immune cells that are designed to soothe could improve treatment for organ transplants, type 1 diabetes and other autoimmune conditions. When the immune system overreacts and starts attacking the body ...
Profiling the proteins that cells are making is a staple of studies in biology, neuroscience and related fields because the proteins a cell is expressing at a given moment can reflect the functions ...
