Validation experiment designed to validate causal mechanisms targeting AMPK, mTOR in animal ICH model. Primary outcome: therapeutic effects of iPSC-NPC transplantation
This experiment evaluated the therapeutic effects of induced pluripotent stem cell-derived neural progenitor cell (iPSC-NPC) transplantation in an in vivo intracerebral hemorrhage (ICH) model. The study investigated how iPSC-NPCs influence the AMPK/mTOR signaling pathway and autophagy regulation in the context of stroke recovery. Researchers analyzed protein and mRNA expression changes of key markers including GFAP (glial fibrillary acidic protein), AMPK, mTOR, SQSTM1/P62, and LC3 (microtubule-associated protein 1 light chain 3) using immunofluorescence techniques. The experiment demonstrated that iPSC-NPCs secrete cytokines that mitigate brain injury and protect astrocytes from autophagy by promoting astrocyte activation through inhibiting AMPK phosphorylation and promoting mTOR activation.
iPSC-NPC transplantation followed by analysis of protein and mRNA expression, immunofluorescence of GFAP, AMPK, mTOR, SQSTM1/P62, and LC3
iPSC-NPCs would promote behavioral recovery and neural connectivity
reduced brain injury, astrocyte protection from autophagy, modulation of AMPK/mTOR pathway
