Transcriptional profiles of valvular interstitial cells cultured on tissue culture polystyrene, on 2D hydrogels, or within 3D hydrogels

Valvular interstitial cells (VICs) actively maintain and repair heart valve tissue; however, persistent activation of VICs to a myofibroblast phenotype can lead to aortic stenosis (Chen and Simmons, 2011) [1]. To better understand and quantify how microenvironmental cues influence VIC phenotype, we compared expression profiles of VICs cultured on/in poly(ethylene glycol) (PEG) gels to those cultured on tissue culture polystyrene (TCPS), as well as fresh isolates. Here, we present both the raw and processed microarray data from these culture conditions. Interpretation of this data can be found in a research article entitled "Microarray analyses to quantify advantages of 2D and 3D hydrogel culture systems in maintaining the native valvular interstitial cell phenotype" (Mabry et al., 2015) [2].
