Human cancer cells with nuclei (specifically the DNA) stained blue. The central and rightmost cell are in interphase, so the entire nuclei are labeled.The cell on the left is going through mitosis and its DNA has condensed.
To keep cells alive during observation, the microscopes are commonly enclosed in a micro cell incubator (the transparent box). Live-cell imaging is the study of living cells using time-lapse microscopy. It is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics.

The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
Human egg cell. The egg cell or ovum (pl.: ova) is the female reproductive cell, or gamete, [1] in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one).
In 1951, Henrietta Lacks was admitted to the Johns Hopkins Hospital with symptoms of irregular vaginal bleeding; she was subsequently treated for cervical cancer. [9] Her first treatment was performed by Lawrence Wharton Jr., who at that time collected tissue samples from her cervix without her consent. [10]
In systems biology, live single-cell imaging is a live-cell imaging technique that combines traditional live-cell imaging and time-lapse microscopy techniques with automated cell tracking and feature extraction, drawing many techniques from high-content screening.
A series of biochemical switches control transitions between and within the various phases of the cell cycle.The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases.
Modern evidence suggests that early cellular evolution occurred in a biological realm radically distinct from modern biology. It is thought that in this ancient realm, the current genetic role of DNA was largely filled by RNA, and catalysis was also largely mediated by RNA (that is, by ribozyme counterparts of enzymes).
