AIMS: Differentiation of cardiac fibroblasts (Fbs) into myofibroblasts (MyoFbs) is responsible for connective tissue build-up in myocardial remodelling. We examined MyoFb differentiation and reversibility. METHODS AND RESULTS: Adult rat cardiac Fbs were cultured on a plastic substratum providing mechanical stress, with conditions to obtain different levels of Fb differentiation. Fb spontaneously differentiated to proliferating MyoFb (p-MyoFb) with stress fibre formation decorated with alpha-smoo ...[more]
Project description:Inflammation is a key component of pathological angiogenesis. Here we induce cornea neovascularisation using sutures placed into the cornea, and sutures are removed to induce a regression phase. We used whole transcriptome microarray to monitor gene expression profies of several genes Overall design: This was a time course study conprising two arms. In the suture IN arm, sutures were maintained in the cornea after the 0h time point, while suture OUT arm is where both sutures were removed from the cornea at the 0h timpoint. 0h timepoint is when sprouts were 3/4 the distance from the pre-existing limbal vessels towards the sutures. Microarrays were performed at 0h, 24h suture IN and 24h suture OUT. Non sutured eyes from separate animals were used as controls. At each time point except for 0h=3 rats, the rest of the timepoints had four rats each.
