title: Micro-CT technique for three-dimensional visualization of human stem cells.
abstract: Micro-CT offers high spatial resolution of the distribution of stem cells and provides rapid reconstruction of 3D images and quantitative volumetric analysis. Together with real-time PCR analysis, micro-CT offers the possibility to obtain a quantification of the number of cells that are able to migrate from the bloodstream inside the muscular tissues. Here, we studied for the first time the kinetics of the human cells injected into the femoral artery of DMD animal model. It is fundamental to determine whether the cells disseminate and entrap only within the capillary system of downstream muscles and/or they are able to reach the non-injected muscles and other organs through blood flow. The efficient transplantation of stem cells to dystrophic-deficient muscle reinforced the utility of intra-arterial delivery of cells as a viable approach for cell-based clinical therapies of neuromuscular diseases.
