Abstract: The present invention relates to a method for obtaining connective mesenchymal stem cells from the mononuclear fraction of human bone marrow cells using type AB human serum as a supplement. Said method includes the steps of obtaining said mononuclear fraction of bone marrow, the step of recovering and pre-expanding the connective stem cells and the step of expanding the connective stem cells until obtaining the clinical dose required for the therapeutic use thereof.

Abstract: Procedure for the undifferentiated or myeloid lineage biased expansion of haematopoietic stem cells coming from umbilical cord blood, mobilized peripheral blood or bone marrow. Procedure for the undifferentiated or myeloid lineage biased expansion of haematopoietic stem cells (HSCs). More specifically, the present invention relates to a procedure of expansion of HSCs from umbilical cord blood, bone marrow or mobilized peripheral blood. Said procedure comprises the steps of expansion culturing of the purified CD34+ cells at constant volume, expansion culturing of said cells at variable volume and the conditioning of the CD34+ cells for transplantation. With this procedure the dose of undifferentiated or myeloid lineage biased HSCs which is necessary for their clinical use is produced reproducibly, robustly and safely.
