Cell Proliferation

Was ist der Zellzyklus?
Was ist der Zellzyklus?
The cell cycle refers to the sequence of events occurring throughout a typical cell’s life. In eukaryotic cells, the somatic cell cycle has two ...
Interphase
Interphase
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of the ...
Das Cell Cycle Control System
Das Cell Cycle Control System
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent ...
Positive Regulatormoleküle
Positive Regulatormoleküle
Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic ...
Hemmung der Cdk-Aktivität
Hemmung der Cdk-Aktivität
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be ...
S-CDK initiiert DNA-Replikation
S-CDK initiiert DNA-Replikation
The cell cycle is a series of events leading to DNA duplication followed by the division of cell content to form two daughter cells. The cell cycle ...
M-CDK treibt den Übergang in die Mitose voran
M-CDK treibt den Übergang in die Mitose voran
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it ...
Mitogene und der Zellzyklus
Mitogene und der Zellzyklus
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell ...
Replikative Zellseneszenz
Replikative Zellseneszenz
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while ...
Abnorme Proliferation
Abnorme Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. ...
Zellen koordinieren Wachstum und Proliferation
Zellen koordinieren Wachstum und Proliferation
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their ...
