TSH receptor in adipose cells.
Although there have been reports supporting the presence of the TSH receptor (TSHR) in human adipose tissue, these findings are still not universally accepted. Contributing to the controversy is a paucity of data about the physiological role the TSH receptor might play in adipose cells. In addition to mature lipid-filled adipocytes, adipose tissue also harbors a pool of specialized, fibroblast-like preadipocytes within the stromal-vascular compartment. Upon appropriate induction, preadipocytes can either differentiate into adipocytes or undergo apoptosis. Since TSHR has been detected in preadipocytes and adipocytes, its potential impact on adipose tissue function may relate to differentiation stage-specific cellular properties.
