NR3C1 and dementia: Ginsenoside Rg1 stimulates the proliferation and differentiation of human dental pulp stem cells and facilitates neural differentiation of mouse embryonic stem cells via the GR-dependent signaling pathway (31, 32), which promotes peripheral nerve regeneration in the rat model of nerve crush injury (142) and improves spatial learning-memory in dementia rats after bone marrow mesenchymal stem cell transplant (21).
