Szövetnövekedés

Szövetnövekedés is the Hungarian term for tissue growth. This biological process involves an increase in the number of cells within a tissue or organ, leading to an overall increase in its size. It is a fundamental aspect of development, repair, and adaptation in living organisms.

There are several mechanisms by which szövetnövekedés can occur. Cell proliferation, also known as mitosis, is a primary driver where existing cells divide to create new ones. This is crucial for growth from a single cell to a complex organism and for replacing damaged or old cells. Another mechanism is hypertrophy, where individual cells increase in size rather than number. This is often seen in muscle tissue in response to increased workload.

Szövetnövekedés is tightly regulated by a complex interplay of genetic factors, hormones, growth factors, and environmental cues. Dysregulation of these processes can lead to abnormal tissue growth, such as cancer, where cells proliferate uncontrollably, or developmental disorders. Conversely, controlled szövetnövekedés is essential for healing wounds, regenerating lost limbs in some species, and adapting to physiological changes like pregnancy or exercise. Understanding the intricacies of szövetnövekedés is vital in fields ranging from developmental biology and regenerative medicine to oncology and veterinary science.
