In addition to tissue, DNA/RNA and eDNA samples, somatic cells are also cryopreserved in the LIB biobank. As part of the FOGS, BGE and ZooRepository projects, a cell culture laboratory was set up that has all the necessary facilities for the establishment, growth and thawing of somatic cells.
Obtaining primary cell cultures is the best way to preserve the genetic resources of a species, as the cells retain most of their original properties and functions and can be used for a variety of studies.
For biodiversity research, the main advantages are access to high quality DNA, RNA, proteins and chromosomes, which facilitates the characterisation of species. In addition, living cells represent a growing, i.e. "renewable" resource, which is particularly important for endangered species given the scarcity of research material and the need to limit the number of samples taken.
In addition, cells offer the possibility for conservation strategies: they can be used in conjunction with assisted reproductive technologies to restore genetic diversity. In addition, somatic cells can be reprogrammed into pluripotent stem cells (iPSCs).
Please contact the LIB Biobank if you have access to material that is suitable for cell culture and that you think should be preserved. You can find a short guide here.
