Cells is an international, peer-reviewed, open access journal on cell biology, molecular biology, and biophysics, published semimonthly online by MDPI.

Cells are largely composed of compounds that contain carbon. The study of how carbon atoms interact with other atoms in molecular compounds forms the basis of the field of organic chemistry and plays a large role in understanding the basic functions of cells.

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 function in all organisms, and that all cells come from pre-existing cells.

Cells publishes the highest quality Research Articles, Reviews, Communications and Editorials. Full experimental details must be provided so that the results can be reproduced.

All living organisms consist of one or more cells. Cells can exist independently (unicellular) or as part of multicellular organisms. Two main types of cells exist: prokaryotic (without a nucleus) and eukaryotic (with a nucleus). Cells contain specialized structures (organelles, in eukaryotic cells) that perform distinct functions.

Since 1994, CELLS alive! has provided students with a learning resource for cell biology, microbiology, immunology, and microscopy through the use of mobile-friendly interactive animations, video, puzzles, quizzes and study aids.

Cell publishes peer-reviewed articles reporting findings of unusual significance in any area of experimental biology.

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.

Cells is a monthly peer-reviewed open-access scientific journal that covers all aspects of cell and molecular biology, and biophysics. It was established in 2012 and is published by MDPI.
