What is a key benefit of using fibroblast cells in cytogenetic studies?

Fibroblast cells are often used in cytogenetic studies due to their ability to survive longer in culture compared to other cell types. This longevity in culture allows researchers to conduct extended experiments and obtain more reliable and extensive data over time. The capacity for prolonged survival is particularly important when performing analyses that require multiple passages or when waiting for specific cellular events to occur.

In contrast, other cell types, such as lymphocytes, may have a shorter lifespan in culture, which limits the duration and depth of studies that can be performed with them. Thus, the use of fibroblast cells facilitates more comprehensive cytogenetic analyses, making them a valuable tool in the field.
