A Novel Conductive Polypyrrole‐Chitosan Hydrogel Containing Human Endometrial Mesenchymal Stem Cell‐Derived Exosomes Facilitated Sustained Release for Cardiac Repair (Adv. Healthcare Mater. 10/2024)

Bioactive Cell‐free Conducting Hydrogel In article 2304207, Sanyuan Zhang, Sheng He, Ren‐Ke Li, Jun Xie, and co‐workers show new strategies for heart tissue engineering. PPY‐CHI is conductive biomaterial and can repair damaged conduction in heart. This biocompatible conductive hydrogel is a platform to carry biological hEMSCExo for long‐term releasing and become a multifunctional biomaterial. It not only enhances tissue regeneration but also reduces arrhythmia through resynchronization.
