Definitions
- the invention relates to a method for cell preparation of mononuclear cells from bone marrow, in particular for use in stem cell therapy after myocardial infarction.
- the damaged heart muscle tissue is not or not sufficiently recovered, resulting in limited physical performance.
- the deterioration of the pumping function of the heart can be stopped by a cell transplantation of bone marrow cells of the same patient.
- mononuclear cells must be separated from the bone marrow and the patient treated with the separated cell fraction.
- the cell preparation is carried out in a special laboratory. This is very expensive. These costs are partly due to statutory provisions of the German Medicines Act, but these do not apply if the collection, preparation and transplantation are in the hands of one and the same natural person (doctor) and the cells are prepared under clean room conditions. It is therefore desirable to carry out the cell preparation at the treatment site.
- the preparation under clean room conditions is a problem.
- the object of the invention is to provide a method for cell preparation of mononuclear cells from bone marrow, which can be carried out with reasonable equipment and economic effort on site and under the supervision of a natural person.
- the solution according to the invention provides that a large volume of peripheral blood is added to a small volume of bone marrow and in that the preparation of the mononuclear cells under clean room conditions is carried out by means of a commercial, fully automatic apheresis apparatus intended for the separation of blood components from blood.
- the method of the invention works best when a volume of 30 ml to 150 ml of bone marrow is mixed with a volume of 150 ml to 350 ml of peripheral blood.
- the bone marrow and the peripheral blood are mixed in a blood bag outside the apheresis apparatus, because the blood taken from the patient is usually filled in such a blood bag, which is also suitable for receiving the bone marrow.
- the blood bag is particularly well suited for mechanical mixing of the two components.
- the apheresis apparatus is adjusted by suitable programming so that the highest possible concentration of the mononuclear cell fraction in the smallest possible final volume is achieved.
- the programming is preferably carried out in accordance with the operating instructions of the apheresis apparatus.
- the volume of the mononuclear cell fraction obtained should be about 5 ml to 7 ml. Much larger volumes would be impractical in administering the cell fraction for therapy.
- the small final volumes can be administered by means of a commercially available syringe.
- the apheresis apparatus is sterile connected to a syringe instead of a conventional collection bag for receiving the separated cell fraction.
- the invention also includes the use of a "Spectra Therapeutic Platform” from Gambo Inc., Lakewood, Colorado, USA for the preparation of a mononuclear cell fraction from a mixture of a small volume of bone marrow and a larger volume of peripheral blood because of positive experience with this machine ,
- the heart of a patient should be treated after having suffered myocardial infarction by means of mononuclear cells to restore its performance.
- a doctor removes 250 ml of blood from the patient, which is collected in a blood bag. Furthermore, the doctor takes the patient 50 ml of bone marrow. The bone marrow is placed under sterile conditions in the blood bag and mixed by hand with the blood. A mixture of 300 ml volume is obtained.
- the blood bag is connected to a "Spectra Therapeutic Platform" apheresis apparatus from Gambro Inc., Lakewood, Colorado, USA, which under sterile conditions separates the mononuclear cell fraction of bone marrow cells under clean room conditions from the mixture of bone marrow and peripheral blood in a fully automated manner
- the apheresis apparatus is sterile connected to a syringe designed to receive the mononuclear cell fraction, which has a volume of 10 ml the syringe is picked up.
- the doctor can remove the syringe and inject the recovered mononuclear cell fraction for therapy purposes in the heart of the patient.
- the invention does not relate to this therapy, but only to the cell preparation.
- the inventive method is very cost-effective, because even with the purchase of a said apheresis system especially for the cell preparation according to the invention suburb lower costs are caused than in a cell preparation in a special laboratory. In addition, in many cases, such Apheresesytem anyway for other purposes will be available, so that the costs can be further reduced thereby.

Abstract
L'invention concerne un procédé particulièrement économique de préparation cellulaire de cellules mononucléaires de moelle osseuse, selon lequel un petit volume de moelle osseuse est ajouté à un grand volume de sang périphérique et selon lequel la préparation de cellules mononucléaires est effectuée, en conditions de salle blanche, dans un appareil d'aphérèse usuel, entièrement automatique et destiné à séparer les constituants du sang.
