What are stem cells?

Stem cells are defined as undifferentiated cells that possess the unique ability to develop into various specialized cell types. This characteristic allows them to play a crucial role in tissue development and repair. Unlike fully differentiated cells, which are tailored for specific functions and cannot transform into other cell types, stem cells retain the potential to differentiate into a range of cells such as muscle cells, nerve cells, or blood cells, depending on the signals they receive from their environment.

Their ability to remain in an undifferentiated state while also having the potential to undergo differentiation is what makes them essential in research and therapeutic applications, particularly in regenerative medicine, where they can help in repairing damaged tissues or organs. Understanding the role of stem cells is fundamental in the study of developmental biology and the treatment of various diseases.
