The team seeded pig intestine grafts with adult stem cells taken from fat tissue in rats.

Mammograms often can't detect dense tissue in obese women because it is hidden by fat cells, Fischbach says.

Obese people can experience chronic inflammation in various tissues, and previous studies show that fat cells can produce and release specific signaling proteins that cause inflammatory responses.

Some possibilities include the ready availability of quick energy in the stored fat, or the fact that the fat may provide an accessible source of lipid - based signaling molecules to facilitate communication between cells or tissues.

Low temperatures activate the brown - fat thermogenesis process via the sympathetic nervous system: Nerve ends in brown fat tissue release the neurotransmitter norepinephrine, and that triggers a shift in metabolism within the brown fat cells, which are densely packed with tiny biological energy reactors called mitochondria.
