Expression of myelin basic protein in injured and treated spinal cords of rats. RT-PCR analysis of myelin basic proteins depicting SCI, SCI-MO, SCI-hUCBSC, and SCI-MO-hUCBSC groups. Housekeeping gene GAPDH was utilized as loading control. Note. RT-PCR = reverse transcription-polymerase chain reaction; hUCBSC = human umbilical cord blood stem cell; MO = Melissa officinalis; SCI = spinal cord injury; GADPH = glyceraldehyde 3-phosphate dehydrogenase.
