title: [Possibility of using hematopoietic stem cells in relation to their generation age].
abstract: A hypothesis of the use of hemopoietic stem cells with a view of satisfying the demand for mature cells depending on their generation age predicts that CFUs that survived after repeated treatment with hydroxyurea should have a greater capacity for self-renewal. It has been demonstrated that after repeated administrations of hydroxyurea according to the scheme devised by the authors of the hypothesis (3-4 times) and as a result of a more prolonged treatment (6 times, every other 12 or 15 h), the capacity of the survived hemopoietic stem cells for self maintenance was not only lower than normal but commonly significantly decreased. The generation-age hypothesis of the use of hemopoietic stem cells thus remains badly needing experimental support.
