Growth Factor and Extracellular Matrix Regulation of Heifer Mammary Development
(Virginia Tech, 2002-08-02)
The overall objective of this project was to investigate the role of locally derived growth factors and extracellular matrix proteins in regulating prepubertal heifer mammary development. In the first experiment, short-term ...
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 ...
