Figure 2From: Simulated microgravity facilitates cell migration and neuroprotection after bone marrow stromal cell transplantation in spinal cord injurymRNA expressions of the graft cells. Effect of simulated microgravity on the graft cells. (A) mRNA expressions of Oct-4, CXCR4, NGF, and BDNF at day 7. The expression of Oct-4 and CXCR4 mRNAs was observed to be stronger in group CL cells. Expression of the housekeeping gene G3PDH was used to standardize expression. Immunostaining (B) indicated that the number of CXCR4-positive cells was significantly greater (P < 0.01) in group CL than in group 1G (n = 5 per group). Data are expressed as mean ± SD. CXCR4-positive cell percentage was significantly higher (P value < 0.01) in group CL than in group 1G.Back to article page
