Abstract
The ability of growth hormone (GH) to stimulate lipolysis was examined using chicken abdominal adipose tissue explants incubated in vitro and purified pituitary and bacterially derived chicken and bovine GH. Consistently in the fourth hour of incubation, lipolysis (as determined by glycerol release) was increased by the presence of GH (1 μg/ml), irrespective of pituitary or bacterial derivation or of chicken or bovine origins. This effect of GH was observed with adipose tissue originating from young (6-8 weeks old) intact and hypophysectomized chicks and adult (6-9 months old) male chickens. Glycerol release was also enhanced by lower doses of GH (10 ng/ml with tissue from young and 100 ng/ml with tissue from adult chickens).
