Brain tissue from (A) non-induced group; (B) Sham group: showing severe leukocyte infiltration (* in yellow); (C) WJ-MSCs therapy group: mild parenchymal infiltration (black arrows); (D) NPs therapy group: demonstrating cell death, pycnotic neurons (black arrows); (E) WJ-MSCs + NPs therapy group: showing astrocyte activation (black arrows). All stained with H&E obtained byoptical microscopy (Carl Zeiss Microscopy, Zeiss, Jena, Germany). Simulation of surgical stereotaxic treatment (Sham); Wharton’s jelly mesenchymal stem cells (WJ-MSCs), neural precursors (NPs).
