Cell publishes findings of unusual significance in any area of experimental biology, including but not limited to cell biology, molecular biology, neuroscience, immunology, virology and microbiology, cancer, human genetics, systems biology, signaling, and disease mechanisms and …

Publisher of over 50 scientific journals across the life, physical, earth, and health sciences, both independently and in partnership with scientific societies including Cell, Neuron, Immunity, Current Biology, AJHG, and the Trends Journals.

Cells emerged on Earth about 4 billion years ago. All cells are capable of replication, protein synthesis, and motility. Cells are broadly categorized into two types: eukaryotic cells, which possess a nucleus, and prokaryotic cells, which lack a nucleus but have a nucleoid region.

6 days ago · cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other …

Jun 14, 2025 · 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 cell is prokaryotic or eukaryotic, and whether it …

Dec 19, 2023 · Cells are the basic units of life. The body contains around 50—100 trillion cells, and they vary widely in size, number, structure, and use. Cells also communicate with each other. Whether in...

Mar 8, 2022 · A cell is the smallest living unit. Inside every cell is a host of structures known as organelles. “Every cell has essential structures that are the same, like every house has a kitchen sink and a bed. But how big and complex they are, and how many of them there are, is going to vary from cell type to cell type,” says Katherine Thompson-Peer.

All cells evolved from a common ancestor and use the same kinds of carbon-based molecules. Learn how cell function depends on a diverse group of nucleic acids, proteins, lipids, and sugars.

Feb 22, 2021 · The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell shape, participating in cell division, and allowing cells to move.

Apr 7, 2024 · Key cellular components, such as the cell wall and cell membrane, bestow support and form to organisms. For instance, human skin comprises myriad cells, while in vascular plants, the xylem, composed of specialized cells, imparts structural robustness.
