Human mesenchymal stem cells (hMSCs) are considered to be a promising tool for novel cell-based therapies. Clinical applications in solid organ transplantation were hampered by the dependence on animal serum for hMSCs clinical scale expansion until substitution with human platelet lysate (HPL) became a promising alternative. Therefore we focused on a direct comparison of immunomodulatory properties of hMSCs cultured in HPL or fetal calf serum (FCS). Phenotypic characterization, detection of cytokine secretion and effects on alloantigen- and mitogen-induced lymphocyte proliferation as well as degranulation of cytomegalovirus-specific cytotoxic T cells were applied in potency assays. We demonstrated that HPL-cultured MSCs have comparable immunomodulatory capacities to their FCS-cultured counterparts. The observed immunomodulatory properties include a beneficial inhibitory effect on immune cell proliferation and an unaffected viral T cell immunity. Thus, culturing hMSCs in HPL generates an efficient and safe expansion combined with intriguing immunomodulatory properties making these cells an attractive cell therapeutic tool.

The transference of BONE MARROW from one human or animal to another for a variety of purposes including HEMATOPOIETIC STEM CELL TRANSPLANTATION or MESENCHYMAL STEM CELL TRANSPLANTATION.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
The process of generating white blood cells (LEUKOCYTES) from the pluripotent HEMATOPOIETIC STEM CELLS of the BONE MARROW. There are two significant pathways to generate various types of leukocytes: MYELOPOIESIS, in which leukocytes in the blood are derived from MYELOID STEM CELLS, and LYMPHOPOIESIS, in which leukocytes of the lymphatic system (LYMPHOCYTES) are generated from lymphoid stem cells.
Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.
Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.
