Which extra thyroid tissues have thyrotropin (TSH) receptors?
['GD orbital fibroblasts, which comprise a mixture of CD34(+) and CD34(-) cells, express much lower levels of Tg and TSHR', 'Previously, we found that CD34(+) progenitor cells, known as fibrocytes, express functional TSHR, infiltrate the orbit, and comprise a large subset of orbital fibroblasts in TAO. ', 'TSH induced lipolysis in adipose tissues.', 'TSH worked as a lipolytic factor in white adipose tissues,', 'These fibrocytes infiltrate orbital connective tissues in thyroid-associated ophthalmopathy and express functional TSH receptor (TSHR). ', 'TSHR levels are higher than those in orbital fibroblasts.']
['TSH receptors are expressed also in extrathyroid tissues. TSH receptors seem to be functional. Extrathyroid tissues include fibrobasts of the orbit and adipose tissue\nThe principal tissues with TSH receptors are:\nadippose tissue\n orbital fibrotic tissue']
['adipose tissue', 'fibrotic tissue']
