Engraftment of Human Primary Acute Myeloid Leukemia Defined by Integrated Genetic Profiling in NOD/SCID/IL2rγnull Mice for Preclinical Ceramide-Based Therapeutic Evaluation.

Acute Myeloid Leukemia (AML) is a highly heterogeneous and poor prognosis disease with few available therapeutic options. Novel advances are urgently needed, however effective models to test experimental therapeutics have been lacking. Recently, NOD/SCID/IL2rγnull (NSG) mice were shown to engraft primary human AML in a manner that recapitulated the natural disease and its progression.

Distribution of murine adipose-derived mesenchymal stem cells in vivo following transplantation in developing mice.

Systemic delivery of mesenchymal stem cells (MSCs) or stromal cells in vivo is attractive because it offers means of disseminating therapeutic cells to various tissues and organs in vivo. In the present study, we investigated the distribution and engraftment of the murine adipose-derived mesenchymal stem cells (ADSCs) without exposure to or exposed to bone microenvironment or transforming growth factor-beta1 (TGF-beta1) prior to transplantation into developing mice. The ADSCs harvested from the murine inguinal fat pad exhibited potential for differentiation toward osteogenic and adipogenic cell lineages in vitro.
