As a cell mediated-process, valvular heart disease (VHD) results in significant morbidity and mortality world-wide. In the US alone, valvular heart disease VHD is estimated to affect 2.5% of the population with a disproportionate impact on an increasing elderly populous. It is well understood that the primary driver for valvular calcification is the differentiation of valvular interstitial cells (VICs) into an osteoblastic-like phenotype. However, the factors leading to the onset of osteoblastic-like VICs (obVICs) and resulting calcification are not fully understood and a more complete characterization of VIC differentiation and phenotypic change is required before treatment of valve disease or …

Drugs tested on animal models do not always produce the same results in humans; a reliable in vitro lung model can bridge the divide between the two. Because the alveolus is a target for several drugs, an alveolar model can be a platform for both designing drugs and studying lung diseases. A model should allow for gas exchange, growth of primary alveolar epithelial cells, extracellular matrix production, and have similar mechanical properties to alveoli, creating an environment conducive to normal metabolic activity and cellular responses. Existing artificial alveolar models that use polymeric membranes to sustain lung cells are limited by …
