    ..Our data suggest a lack of cellular differentiation capacity in WRS patients, which may be responsible for the clinical appearance and symptoms of this rare disorder. ..
  2. Jager M, Sager M, Knipper A, Degistirici O, Fischer J, Kogler G, et al. [In vivo and in vitro bone regeneration from cord blood derived mesenchymal stem cells]. Orthopade. 2004;33:1361-72 pubmed
    ..Human USSC are a mesenchymal multipotent stem cell population that shows osteoblastic differentiation onto a collagen I/III carrier in vitro as well as in an athymic rat in vivo. ..
  3. Jager M, Degistirici O, Knipper A, Fischer J, Sager M, Krauspe R. Bone healing and migration of cord blood-derived stem cells into a critical size femoral defect after xenotransplantation. J Bone Miner Res. 2007;22:1224-33 pubmed
    ..Human cord blood-derived stem cells showed significant engraftment in bone marrow, survived within a collagen-TCP scaffold up to 4 wk, and increased local bone formation in a nude rat's femoral defect. ..
  4. Jager M, Krauspe R. Antigen expression of cord blood derived stem cells under osteogenic stimulation in vitro. Cell Biol Int. 2007;31:950-7 pubmed
    ..Future investigations should show the role of cytomechanical forces in the differentiation of cord blood derived progenitor cells and also if a cell-loaded collagen I/III scaffold is appropriate to stimulate bone regeneration in vivo. ..

    ..In conclusion, BMP-2 enhances DAG-induced osteogenic differentiation in mesenchymal bone marrow cells. Both agents interact in various ways and can modify osteoblastic bone formation. ..
