Thanks, that's great stuff. From what you found, the abstracts only reference results that compare either a "high" or "low" amount of M1 or M2 macrophages. I don't know if you have access to the full articles? I'm just wondering if there's anything there that indicates what they mean by "high" and "low"? This graph implies that bavi is increasing the amount of M1 macrophages by four fold compared to the amount seen in a normal tumor environment.
