Activated macrophages create lineage-specific microenvironments for pancreatic acinar- and β-cell regeneration in mice.

Criscimanna A, Coudriet G, Gittes G, Piganelli J, Esni F (2014) Activated macrophages create lineage-specific microenvironments for pancreatic acinar- and β-cell regeneration in mice. Gastroenterology 147:1106-1118.e1111. doi: 10.1053/j.gastro.2014.08.008

Summary: In response to tissue damage or infection, monocytes are recruited to the injured area and differentiate into macrophages. These macrophages can perform different functions depending on the tissue type. The specific differentiation macrophages undergo in response to their environment is called polarization. The authors used a mouse pancreatic lesion model to examine the polarization of macrophages into the two distinct states known, M1 and M2. Mice received 20 μg of Mac-1-SAP mouse (Cat. #IT-06) in a tail vein injection following a pancreatic lesion, and were sacrificed on various days post-injection in order to evaluate macrophage presence at different response stages. The results demonstrate that various aspects of macrophage polarization are required for pancreatic regeneration.
