PLG and neoplasm: To evaluate whether MPs and Man-MPs can degrade tumor ECM by MMP activity, PKH26-labeled MPs or Man-MPs pretreated with or without Bati or 4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF, an inhibitor of serine proteases, such as plasminogen activation system involved in the activation of a number of MMPs49) were incubated with collagen I film.
