Human corneal equivalents comprising the three main layers of the cornea (epithelium, stroma, and endothelium) were constructed. Each cellular layer was fabricated from immortalized human corneal cells that were screened for use on the basis of morphological, biochemical, and electrophysiological similarity to their natural counterparts. The resulting(More)
One-third of women with breast cancer will develop bone metastases and eventually die from disease progression at these sites. Therefore, we analyzed the ability of human MG-63 osteoblast-like cells (MG-63 cells), MG-63 conditioned media (MG-63 CM), insulin-like growth factor I (IGF-I), and transforming growth factor beta 1 (TGF-beta1) to alter the effects(More)
The available monolayer culture systems for the study of bone metastases constitute a suboptimal simulation of the in vivo pathophysiology of bone metastases, and therefore, do not provide sufficient information to assess the morphologic evidence of bone reaction to cancer cells, the nature of cell-specific mediators of osteolysis and osteoplasia and the(More)
Our objectives were to investigate the interactions between mammary cancer epithelial cells (MCF-7) and stromal cells (Hs-578Bst) at the level of the expression and inhibition of steroidogenesis enzymes by using monolayer and three dimensional co-culture models. Expressions of steroidogenesis enzymes and E2/DHT conversions in co-cultured MCF-7 and Hs-578Bst(More)
Collagen is a widely investigated extracellular matrix material with extensive potentials in the field of tissue engineering. This protocol describes a method to prepare reconstituted collagen that can be ready-to-use, storable and suitable for further in vitro and in vivo investigations. Type I collagen was extracted from rat tail tendons and processed in(More)
