Interestingly, we found a significantly greater synthesis of GAP-43 in 4G-BMHP1 group (12.94±2.03% of the whole cyst area) in comparison with saline (6.33±1.7% of the whole cyst area) and SCI control (5.84±1.29% of the whole cyst area) groups (Figure 2Bii). The gene discussed is GAP43; the disease is cyst.
