Mesenchymal Stem Cells In Neurodegenerative Disease Therapy is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Mesenchymal stem/stromal cells (MSCs) have emerged as a promising therapeutic approach for neurodegenerative diseases. These multipotent cells can be derived from various tissues and exert neuroprotective effects through multiple mechanisms.
- Sources: Bone marrow, adipose tissue, umbilical cord, dental pulp
- Surface markers: CD73, CD90, CD105, negative for hematopoietic markers
- Differentiation potential: Adipogenic, chondrogenic, osteogenic, neurogenic
- Immunomodulatory capacity: Low immunogenicity, immunosuppressive properties
-
Paracrine signaling
- Growth factor secretion (BDNF, GDNF, NGF)
- Anti-inflammatory cytokines
- Antioxidant factors
-
Immunomodulation
- T cell modulation
- Microglial activation shift
- Reduced cytokine toxicity
-
Mitochondrial transfer
- Functional mitochondria transfer to受损 neurons
- Metabolic support
