[First results of in vitro cultivation of stem cells from bone marrow and peripheral blood in an autologous test system of patients with hematological diseases].

In 17 patients with haematological diseases an autologous test system was elaborated for determining the percentage of unipotent myeloic stem cells in the bone-marrow and peripheral blood and implemented by experiments. In comparing the results obtained by means of the traditional heterologous culture method, differences (diminutions, increase of aggregate numbers) could be found which allow certain conclusions to be drawn on the patient's real bone marrow function. For reasons of standardization, cultivation in the heterologous system cannot be abandoned. The investigations are continued.
