sejttárház

A sejttárház, often translated as cell bank or cell repository, is a facility where biological samples, typically cells or cell lines, are stored for long-term preservation. These stored cells are cryopreserved, meaning they are kept at extremely low temperatures, usually in liquid nitrogen, to halt their biological activity and prevent degradation. This process ensures the viability of the cells for extended periods, sometimes decades.

The primary purpose of a sejttárház is to safeguard valuable cell collections for various scientific and medical applications. This includes preserving primary cell cultures derived from specific tissues or organisms, established cell lines used in research and drug development, stem cells for regenerative medicine, and even germ cells (sperm and eggs) for fertility preservation or breeding programs.

Sejttárházak play a crucial role in research reproducibility, allowing scientists to access consistent cell populations for experiments. They are also vital for maintaining biodiversity, preserving endangered species' genetic material, and supporting the development of new therapies. The meticulous storage and cataloging systems within these facilities are essential for ensuring the integrity and accessibility of the stored biological samples. Access to these stored cells is typically controlled and granted based on specific research protocols or medical needs.
