Cardiac fibrosis inhibitor CTPR390 prevents structural and morphological changes in human engineered cardiac connective tissue.

ABSTRACT: Cardiac fibrosis is a key characteristic of heart failure. CTPR390, an experimental anti-fibrotic inhibitor targeting Hsp90, has shown success in animal models, but remains unexplored in human cardiac models. This study evaluated an engineered cardiac connective tissue (ECCT) model, focusing on changes in the extracellular matrix and fibroblasts. Results showed that CTPR390 prevented architectural changes in TGFβ1-activated ECCT, preserving tissue perimeter, collagen fibers alignment while reducing structured areas and degree of collagen structuration. CTPR390 treatment reduced cell area of fibroblasts under tension, without changes in the internal rounded cells devoid of tension. Fibroblast recruitment to tension areas was diminished, showing biomechanical behavior similar to control ECCT
