Lab-grown dopamine cells aim to reboot movement in Parkinson’s patients

Researchers are testing implanted induced pluripotent stem cells engineered to become dopamine-producing neurons in the brains of Parkinson’s patients in a Phase 1 trial. Delivered via MRI-guided surgery into the basal ganglia, the goal is to restore dopamine production, improve motor function, and slow disease progression. The 12-person study (RNDP-001) is monitored for 12–15 months with long-term follow-up planned for up to five years to assess safety (e.g., dyskinesia, infection) and efficacy, and it has FDA fast-track designation.

Diverse autism mutations converge on a shared chromatin-regulation network in stem-cell–derived human cortex

A large hiPSC-based study generated cortical organoids from eight ASD-risk mutations, idiopathic ASD, and controls, profiling gene expression across 25–100 days. Early mutation-specific changes give way to convergent transcriptional and chromatin-regulatory disruptions enriched for ASD risk genes, including SWI–SNF components. CRISPRi validation supports key regulators driving this convergent network, suggesting that diverse genetic risks in ASD propagate through shared transcriptional pathways that affect early neurodevelopment, while idiopathic cases show less convergence.
