Transverse section of spinal cord showing the ventral horn gray matter of spinal cord at the level of T12-L1 of all groups which were evaluated in this study on Day 56. Black arrows illustrate the GFAP astrocytes. Reduced GFAP astrocytes are evident. a = Intact, b = SCI, c = SCI-MO, d = SCI-hUCBSC, e = SCI-MO-hUCBSC. Bar = 50 µm. (ECLIPSE 5Oi microscope). Note. GFAP = glial fibrillary acidic protein; hUCBSC = human umbilical cord blood stem cell; MO = Melissa officinalis; SCI = spinal cord injury.
