Comparative transcriptome analysis reveals a fetal origin for mesenchymal stem cells and novel fetal surface antigens for noninvasive prenatal diagnosis

Mesenchymal stem cells (MSCs) are an attractive source for providing the cells necessary for regenerating damaged tissues. Fetal MSCs (fMSCs) are known to proliferate fast and have an excellent osteogenic capacity, yet the underlying mechanisms need to be explored. A better understanding of MSCs from different anatomic origins and ages will eventually benefit cell-based therapies, as well as subsequent mechanistic studies in the field of stem cell biology.
