Scheme 1From: Sustained delivery of MMP-9 siRNA via thermosensitive hydrogel accelerates diabetic wound healingSchematic Illustration of preparation of the hybrid hydrogel dressing. The siMMP-9 is first complexed with GT, then GT/siMMP-9 is mixed completely with PF-127 and methylcellulose. This hybrid hydrogel undergoes a sol-gel transition in situ and then deliver sustained siMMP-9 to the diabetic wound areaBack to article page
