Sejtvándorlás

Sejtvándorlás, also known as cell migration, is a fundamental biological process where cells move from one location to another within an organism. This directed movement is crucial for a vast array of physiological and pathological events. In embryonic development, sejtvándorlás guides cells to form tissues and organs, a process essential for shaping the body. During wound healing, cells migrate to the injured site to repair damaged tissue. The immune system relies heavily on sejtvándorlás for white blood cells to travel to sites of infection or inflammation to combat pathogens.

However, uncontrolled or aberrant sejtvándorlás is implicated in serious diseases. Cancer metastasis, the spread of cancer cells from a primary tumor to distant parts of the body, is a prime example where cell migration plays a critical role. The process involves complex molecular mechanisms, often triggered by external stimuli or internal cellular cues. Cells employ various strategies to migrate, including amoeboid movement and mesenchymal migration, each involving distinct cytoskeletal rearrangements and cell adhesion dynamics. Understanding the intricate pathways governing sejtvándorlás is a significant area of research, offering potential targets for therapeutic interventions in diseases characterized by abnormal cell movement.
