transit amplifying cell
Quick Summary
A transit-amplifying cell is a stage in cell differentiation. This process involves an immature cell developing into a specialized cell type with a distinct structure and function.1
The stages of cell differentiation are:
* Stem cell stage: An undifferentiated cell that can divide to produce more stem cells or cells destined to differentiate.2
* Progenitor cell stage (transit-amplifying cell): These cells arise from stem cells and undergo a limited number of divisions, becoming increasingly specialized with each round.13
* Terminally differentiated cell stage: Cells become fully specialized and typically cease dividing.1
Transit-amplifying cells are crucial for tissue regeneration and repair, as they rapidly produce the cells needed to replace damaged or lost ones. Aberrant differentiation, including issues with transit-amplifying cells, can contribute to diseases like cancer.1
