Desarrollo de tejido cardíaco humano organizado en 3D dentro de una plataforma microfluídica

Overview

This protocol describes the development of a three-dimensional (3D) microfluidic model of human cardiac tissue. The model consists of stem cell-derived cardiomyocytes co-cultured with cardiac fibroblasts in a collagen-based hydrogel, aimed at enhancing cardiac tissue engineering and drug screening.
