Definition
Programmed cell death, or apoptosis, is a regulated process by which cells undergo an orderly sequence of events leading to their self-destruction, often in response to developmental cues or cellular stress. This mechanism is crucial for maintaining tissue homeostasis and eliminating damaged or unwanted cells in multicellular organisms.
Summary
Programmed cell death, or apoptosis, is a crucial biological process that allows cells to die in a controlled manner. This process is essential for maintaining health, as it helps eliminate damaged or unnecessary cells without causing harm to surrounding tissues. Apoptosis plays a significant role in various biological processes, including development, immune response, and tissue homeostasis. Understanding apoptosis is vital for comprehending how organisms develop and how diseases, particularly cancer, can arise from its dysregulation. By studying the mechanisms of apoptosis, researchers can develop targeted therapies that can restore normal cell death processes, offering hope for effective treatments for various diseases.
