SCHEME 1.
Design of ROS‐responsive T3 delivery through NSC nanoencapsulation in ICH cell therapy. ROS‐induced cell apoptosis and a lack of differentiation inducers are two major problems in NSC transplantation for ICH. By means of single‐cell nanoencapsulation with an ROS‐responsive T3 complex, apoptosis was attenuated, and oligodendrogenesis was promoted in transplantation therapy.
