Technology Approaches
iPSC-Derived Neurons Induced pluripotent stem cells (iPSCs) offer the potential for patient-specific, immune-matched cell therapies:
Autologous iPSCs : Patient-derived cells minimize immune rejection risk [3](https://doi.org/10.1016/j.stem.2020.02.002)Allogeneic iPSCs : "Off-the-shelf" products from master cell banksGene editing : Correction of disease-causing mutations in patient-derived iPSCsEmbryonic Stem Cell (ESC) Derivatives
Dopaminergic neurons : For Parkinson's disease (clinical trials ongoing)Motor neurons : For ALSRetinal pigment epithelium : For macular degenerationMesenchymal Stem Cells (MSCs)
Immunomodulation : Suppression of neuroinflammation [4](https://doi.org/10.1186/s13287-021-02255-3)Trophic factor secretion : Support for endogenous neuronsSafety profile : Well-established safety in clinical trialsNeural Stem Cells (NSCs)
Endogenous repair : Stimulation of host neural circuitsTrophic support : Secretion of neurotrophic factorsDisease modeling : Platform for drug screeningKey Companies
