Adipose tissue, or fat, is an anatomical term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.

Since most of the MCP-1 release by adipose tissue was due to the nonfat cells, we examined MCP-1 release by the pieces of adipose tissue that do not contain enough lipid to float (connective tissue).
