Imagine being a master chef creating a gourmet meal. You have all the right ingredients, but you need the perfect recipe. That’s where pluripotent stem cells come in, acting as the versatile ingredients for rebuilding the human brain. Just like a chef can transform raw ingredients into a variety of delectable dishes, scientists can use stem cell technologies to differentiate these cells into highly specialized types of neurons like cholinergic, dopaminergic, and motor neurons. By doing so, they hope to develop therapeutic options for devastating neurodegenerative disorders such as Alzheimer’s, Parkinson’s, Huntington’s, ataxia, and amyotrophic lateral sclerosis. But it doesn’t stop there! Not only can they generate neurons, but they can also create glial cell populations like oligodendrocytes and microglia to support neural function. In fact, clinical trials are already underway to test these cell replacement therapies in the nervous system. The potential for regenerative medicine is truly exciting, and further research is needed to unlock its full potential!
Neurodegenerative disorders have been extremely challenging to treat with traditional drug-based approaches and curative therapies are lacking. Given continued progress in stem cell technologies, cell replacement strategies have emerged as concrete and potentially viable therapeutic options. In this review, we cover advances in methods used to differentiate human pluripotent stem cells into several highly specialized types of neurons, including cholinergic, dopaminergic, and motor neurons, and the potential clinical applications of stem cell-derived neurons for common neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, ataxia, and amyotrophic lateral sclerosis. Additionally, we summarize cellular differentiation techniques for generating glial cell populations, including oligodendrocytes and microglia, and their conceivable translational roles in supporting neural function. Clinical trials of specific cell replacement therapies in the nervous system are already underway, and several attractive avenues in regenerative medicine warrant further investigation.
