This usually results in the restoration of the lipid deficit through compensatory increases in nonexcised white adipose tissue (WAT) masses of ground squirrels, laboratory rats, and mice, as well as Siberian and Syrian hamsters. We challenged this hypothesized total body fat regulatory system by testing the response of Siberian hamsters to 1) lipid deficits [lipectomy; primarily bilateral epididymal WAT (EWAT) removal], 2) lipid surfeits (addition of donor EWAT with no lipectomy), 3) no net change in lipid [EWAT or inguinal WAT (IWAT) lipectomy with the excised fat replaced to a new location (autologous)], 4) lipectomy with the same pad (EWAT lipectomy only) added from a sibling (nonautologous), and 5) sham surgeries for each treatment. Food intake generally was not affected. Body mass was not affected across all treatments. Grafts \u223c3 mo later had normal appearance both macro- and microscopically and were revascularized. The normal lipectomy-induced compensatory increases in nonexcised WAT masses surprisingly were exaggerated with autologous EWAT transplants, but not for autologous IWAT or nonautologous EWAT transplants. There was no compensatory decrease in native WAT masses with nonautologous EWAT additions. Collectively, only lipectomy triggered reparation of the lipid deficit, but the other manipulations did not, suggesting a system biased toward rectifying decreases in lipid or an inability of the hypothesized total body fat regulatory system to recognize WAT transplants.<\/jats:p>","DOI":"10.1152\/ajpregu.00476.2003","type":"journal-article","created":{"date-parts":[[2004,1,31]],"date-time":"2004-01-31T00:56:28Z","timestamp":1075510588000},"page":"R61-R70","source":"Crossref","is-referenced-by-count":14,"title":["Autologous fat transplants influence compensatory white adipose tissue mass increases after lipectomy"],"prefix":"10.1152","volume":"286","author":[{"given":"Eva L.","family":"Lacy","sequence":"first","affiliation":[{"name":"Department of Biology, Neurobiology and Behavior Program and Center for Behavioral Neuroscience, Georgia State University, Atlanta, Georgia 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy J.","family":"Bartness","sequence":"additional","affiliation":[{"name":"Department of Biology, Neurobiology and Behavior Program and Center for Behavioral Neuroscience, Georgia State University, Atlanta, Georgia 30303"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","reference":[{"key":"REF1","doi-asserted-by":"publisher","DOI":"10.1038\/382250a0"},{"key":"REF2","unstructured":"Ashwell M.The use of the adipose tissue transplantaton technique to demonstrate that abnormalities in the adipose tissue metabolism of genetcally obese mice are due to extrinsic rather than intrinsic factors.Int J Obes9: 77-82, 1985."},{"key":"REF3","unstructured":"Bartness TJ, Demas GE, and Song CK.Central nervous system innervation of white adipose tissue.
