Modeling Synaptic Maturation from Growth Cone to Synapse in Human Organoids
Medicine · Neurology
A new study published in the Journal of Neurochemistry introduces a simple, centrifugation-based method for isolating growth cone particles and immature synaptosomes from human forebrain organoids at distinct developmental stages. The researchers demonstrated that Day 90 isolates were enriched with growth cone markers and responded to KCl-induced depolarization with phosphorylation of proteins involved in pathfinding, while Day 150 isolates contained immature synapses with functional vesicle cycling. For a neuroscientist developing preclinical models of chronic pain, this protocol offers a scalable, human-relevant platform to investigate synaptic dysfunction in neurodevelopmental and neurodegenerative disorders, moving beyond rodent-based approaches.
