No, because in a public bank the samples are stored anonymously. Even if the sample that was stored has not yet been used for research purposes or from someone histocompatible patient, the family will be not able to use its cells that already had donated to the public bank, because they are stored anonymously. A large number of donors is rejected from public banks given the family medical history, the mothers’ medical history, the volume of collection, and the virology tests that are performed to the sample or to the mother’s blood, (Transfusion, January 2000, Vol. 40:1, 124). These donors would not be necessary rejected in the private banking, because virus infections in the family are very rare and the purpose of the family storage is mainly the cellular therapies and not the relative rare cases of leukemia that is the only field of interesting of the public bank. Furthermore one must consider that by rule in the public bank the samples are rejected after some years either because they were renewed with new samples with similar hystocompatibility, or due to lack of space or funding.
