Issues of banking breast cancer cells to generate mammospheres.
Identification of breast cancer stem cells, within the context of the tumor tissue, requires an efficient and standardized method to preserve the functional features of living cells. Although isolating cancer stem cells can be laborious and time-consuming, minimal processing may be advantageous for the banking of specimens from which cultures are not immediately needed. Homogenization of banking procedures will result in a reliable network of biorepositories for cooperative studies and several research groups are focusing on the issues of tissue banks for translational medicine. Most tissue banks collect and freeze unprocessed cancer specimens, which cannot therefore be used to generate viable cells. We discuss the principal issues of biobanking breast cancer living cells and protocols for mammospheres formation from single cell suspension of tumor cells.
