The Role of Exogenous Somatotropin, Ovariectomy and Extracellular Matrix in Bovine Mammary Gland Development
(Virginia Tech, 2010-01-27)
The highly regulated maturation of the mammary gland is poorly understood. Our studies were designed to further characterize the role of ovarian hormones, growth hormone (GH)/IGF axis proteins and extracellular matrix (ECM) ...
Effects of Milk Replacer Composition on Measures of Mammary Development in Holstein Heifer Calves
(Virginia Tech, 2008-04-15)
This study was to evaluate effects of milk replacer (MR) composition on: mass and composition of mammary parenchyma (PAR) and fat pad (MFP), growth hormone (GH)/insulin-like growth factor-I (IGF-I) axis gene expression, ...
The Role of Insulin-like Growth Factor-I and IGF-binding Proteins in Mammary Gland Development
(Virginia Tech, 1998-11-19)
Development of the mammary gland is likely mediated by locally produced growth factors acting in concert with circulating mitogens. To investigate the importance of mammary synthesis of insulin-like growth factor-I (IGF-I) ...
Ovarian and Growth Hormone Regulation of Mammary Growth and Transcript Abundance in Prepubertal Dairy Heifers
(Virginia Tech, 2009-04-03)
Ovarian secretions and growth hormone (GH) are major endocrine regulators of mammary growth and development in bovine mammary gland; but information on endocrine regulation during early prepubertal period is limited. Our ...
Mechanisms Controlling Ductal Morphogenesis in the Ruminant Mammary Gland
(Virginia Tech, 1998-08-17)
Basic research into the histology, endocrine control, and local regulation of prepuberal ruminant mammogenesis was conducted to provide a better understanding of this important developmental period. Histologic features of ...
