Akash I believe you're right. PRPn increase scar tissue who knows, i'll take a look at your paper link. I tend to think scar tissue is reaction of bad inflammation. I was looking recently at serrapeptase an enzyme to break down fibrin or the precursors of fibrin, I'm not sure. I don't know of its use for actual developed scar tissue. I was wondering if injections might help. It has been shown in mice to reduce scar tissue post surgery. Even when taken orally.
