Yes, HeLa cells are known to grow exceptionally fast.
HeLa cells are a particularly aggressive and rapidly dividing cell line. Their rapid growth rate is one of the key reasons they have become such a widely used and studied cell line in scientific research. This rapid proliferation is due to a combination of factors, including their cancerous origin and certain genetic adaptations that allow them to divide more quickly and efficiently than many other cell types.
Here's why their rapid growth is significant:
-
Contamination Risk: Because they grow so quickly, HeLa cells can easily contaminate other cell cultures in a lab setting. This has been a significant problem in the past, as researchers unknowingly worked with HeLa cells instead of the cell line they intended to study.
-
Research Advantages: Their rapid growth makes them easy to culture and maintain in large quantities, making them a convenient tool for various types of experiments. Researchers can quickly obtain a large population of cells for their studies.
-
Immortalized Nature: Unlike normal cells, which have a limited lifespan (Hayflick limit), HeLa cells are considered "immortal" and can divide indefinitely under the right conditions. This contributes to their rapid proliferation over long periods.
In summary, HeLa cells' rapid growth is a defining characteristic that has both advantages and disadvantages in the context of scientific research.
