BMSC-CM reduces lesion extension.

<p>(<b>A</b>) Illustration of an injured spinal cord transversal section invaded by a cyst. For each section, cystic cavity extent (H1) and spinal cord extent (H2) were measured on the median axis. Both values were related to express a ratio in percents. (<b>B</b>) Photomicrographs of Luxol-fast-blue/periodic acid - Schiff/hematoxylin stained sections of BMSC-CM treated and control animals, taken at the lesion epicentre, 6 weeks after injury. Cyst extent is shown by an arrow. (<b>C</b>) Ratio cyst extent/spinal cord extent of BMSC-CM treated and control animals, 6 weeks after injury. BMSC-CM treated animals obtained a ratio significantly reduced compared to control group. 6 animals per group were studied. ** p<0.01.
