What researchers are saying...

“In order to investigate the in vivo role of MMPs, we established a rodent model of glioma progression... We chose continuous infusion using an osmotic pump as the method for delivering TIMP into the tumor. This paradigm allowed aggressive glioma development and circumvented the problem of the blood brain barrier disturbing reagent delivery following intravenous delivery.” Takahashi et al., Pharmacological Research 2002;46(2):155-163.
