HSP27 expression in the sensory dorsal root ganglion (DRG) in healthy (A,C,E,G,I) and in GK diabetic rats (B,D,F,H,J). The left panels: (A) = contralateral uninjured side (14-day model) healthy rats, (C) = no repair (14-day follow-up) healthy rats, (E) = immediate repair (14-day follow-up) healthy rats, (G) = immediate repair (7-day follow-up) healthy rats, and (I) = delayed (7 days) repair (7-day follow-up) healthy rats. The right panels: (B) = contralateral uninjured side (14-day model) GK rats, (D) = no repair (14-day follow-up) GK rats, (F) = immediate repair (14-day follow-up) GK rats, (H) = immediate repair (7-day follow-up) GK rats, and (J) = delayed (7 days) repair (7-day follow-up) GK rats. Bar = 200 μm in all images.
