  • Western blot shows tPA protein level (a) and zymography shows tPA activity (b) in MCAo mice with or without MSC treatment. tPA and PAI-1 expression was significantly increased in the IBZ of mice subjected to MCAo compared with normal mice. tPA expression was significantly increased and PAI-1 expression was significantly decreased in the IBZ of MCAo mice after MSC treatment compared with MCAo alone mice (c).

  • The proteolytic activity of MMP-9 measured by zymography was also significantly diminished in mice treated daily with i.p. injections of minocycline and i.v. injections of PEG minocycline-liposomes every five days (B).

  • Proteolytic activity of MMP-9 was assessed in supernatants of human PBMCs after 24 hrs of stimulation with IL-2 and assessed by gelatin-zymography, as previously described

    PLoS ONE Alerts: New Articles

  • Gelatinolytic activity was detectable by gelatin-zymography at molecular weights of 92 kDa, indicative of MMP-9, in the supernatants from all human PBMC samples studied.
