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.

Human Cell is a peer-reviewed English-language journal that publishes cutting-edge research papers and reviews on all aspects of the human cell including the establishment of cell lines. The official journal of the Japan Human Cell Society.

2025年2月13日 · 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 …

2022年1月12日 · Humans are multi cellular organisms, which roughly have trillions of cells in the human body. They all play an important role in various bodily functions. They form the body’s structure, take in and transport nutrients from foods to the host, convert nutrients to energy, and carry the genetic materials of the body.

2023年12月19日 · A cell is the smallest living organism and the basic unit of life on earth. Together, trillions of cells make up the human body. Cells have three parts: the membrane, the nucleus, and the...

2025年3月27日 · A human cell is the basic unit that makes up your body, kind of like tiny rooms in a massive mansion working together to keep everything running. Picture it as a microscopic bubble with a flexible outer layer—the membrane—that decides what enters or exits. Inside, there’s a gooey mix called cytoplasm, packed with tiny machines that handle different jobs.

2020年8月14日 · Define a cell, identify the main common components of human cells, and differentiate between intracellular fluid and extracellular fluid; Describe the structure and functions of the plasma (cell) membrane; Describe the nucleus and its function; Identify the structure and function of cytoplasmic organelles

2021年2月22日 · The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.

The list of human cell types provides an enumeration and description of the various specialized cells found within the human body, highlighting their distinct functions, characteristics, and contributions to overall physiological processes.

Human Cell Epigenome Atlas. We performed multi-omic profiling of 3D genome structure and DNA methylation for 86,689 single nuclei across 16 human tissues, identifying 35 major and 206 cell subtypes. This browser allows users to interactively visualize the dataset. The genome browser visualizes DNA methylation tracks, contact maps, and putative ...
