Figure Lengend Snippet: Conditional UTX knockout in ECs regulates BSCB permeability following SCI via the MLCK/p-MLC pathway, promoting neurological recovery. a Western blotting analysis of MLCK, p-MLC, MLC in UTX f/f , UTX −/− , UTX −/− + LV CON, and UTX −/− + LV MLCK-OE mice at SCI 3d. b , c Quantitative analysis of the expression levels of MLCK and p-MLC in a . n = 3 per group. d Representative immunofluorescence images of p-MLC (red) and CD31 (green), DAPI (blue) staining of injured epicenter of spinal cord in UTX f/f , UTX −/− , UTX −/− + LV CON, and UTX −/− + LV MLCK-OE mice at SCI 3d. Scale bars, 50 μm. e Quantitative analysis of CD31 + p-MLC + cells as a percentage of CD31 + cells in d , n = 6 per group. f , g Distribution of the BMS scores and BMS sub-scores in UTX f/f , UTX −/− , UTX −/− + LV CON, and UTX −/− + LV MLCK-OE mice at pre-surgery and after SCI throughout the 56-day period. n = 12 per group. h Representative images of motor-evoked potential (MEP) in UTX f/f , UTX −/− , UTX −/− + LV CON, and UTX −/− + LV MLCK-OE mice at 56-day post-SCI. i Quantitative evaluation of the amplitude of MEPs in h . n = 6 per group. Data are represented as mean ± SEM. ns P > 0.05, * P < 0.05, ** P < 0.01
