Implication
Coculture platform demonstrates enhanced NMJ innervation in motor neurons, indicating potential for therapeutic compounds.
Key Points
- The platform shows enhanced NMJ reinnervation after applying blebbistatin to injured motor neurons, revealing therapeutic potential.
- Evidence indicates that SMA-derived motor neurons exhibit reduced NMJ function, specifically in SMA type 0 and type I.
- Real-time monitoring of axon growth, NMJ innervation, and muscle activity provides insights for developing neuroprotective therapies.
- GCaMP6f muscle activity serves as a functional marker for assessing NMJ formation in response to treatments.
