An experimental model system that allows the assessment of the full ­differentiative potential of human mesenchymal stromal/stem cells (MSC) under normal physiological conditions, in the absence of genetic or injury-induced ­dysfunction, could reveal their true capabilities and also provide a valuable tool to dissect the pathways governing differentiation and fate reprogramming. The naturally occurring stem cell migratory patterns, the availability of expanding homing and engraftment sites, and the presence of tissue/organ-specific signals combine to make the developing mammalian fetus an ideal setting for MSCs to display their full biological potential. In addition to these characteristics, the early gestational age fetus also possesses the unique advantage of being relatively immunologically naive, making it possible to achieve engraftment and long-term persistence of MSCs and other stem cells from not only allogeneic but xenogeneic donors as well. In this chapter, we describe the advantages of the pre-immune fetus as a model for studying human MSCs and discuss results we have obtained thus far with a large animal (sheep) fetal model.
