molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. the insulin like growth factor-i (igf-i) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. the objectives of the present study were the estimate the haplotype frequencies of the igf-i gene polymorphisms i...

conclusions this case highlights the fact that fhr and ghd may coexist, with possible masking effect of one on the other, thereby misleading the approach, posing large impacts on therapy, which has historically been a difficult challenge in fhr patients. introduction coincided familial hypophosphatemic rickets (fhr) and hypopituitarism is a rare condition. growth hormone deficiency (ghd) evalua...

when grown in monolayer culture at low density and with the addition of serum, cartilage cells dedifferentiate or are overgrown by fibroblast-like cells. the aim of this study was to optimize the cultivation of chondrocytes in monolayer culture and to slow down their transformation or their overgrowth by fibroblast-like cells. the interaction between chondrocytes and cartilage-specifc matrix is...

Insulin-like growth factor (IGF) remains in the different classes of vertebrates including birds [1,2], reptiles, amphibians [3], fishes [4-6] and mammals [7]. Insulin-like growth factor I (IGF-I) is a protein comprising two major forms, IGF-I and IGF-II [8,9] . The IGF-I is produced from the liver Sjogren et al. [10] by the influence of growth hormone involving the axis of pituitary/hepatic sy...

conclusions igf-1 has the most significant effect on intrauterine growth. acylated ghrelin is detectable in cord blood and correlated with birth weight, suggesting a role in intrauterine development, but its level is not affected by intrauterine growth retardation. results no significant differences were observed in ghrelin and gh concentrations between sga and aga infants. however, igf-1 level...

New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...
