CNS regenerative and neural cell therapy
Parkinson’s, epilepsy, spinal cord injury, ALS, Alzheimer’s disease, and adjacent CNS programs where cells are being tested as defined products.
- Neural cells
- CNS delivery
- Safety follow-up
CellXperience Weekly follows cell therapies entering trials, products moving through regulatory pathways, and papers that sharpen how the field thinks about replacement, repair, and delivery.
Each issue follows a narrow set of cell-therapy developments: CNS programs, iPSC and stem-cell replacement, and selected MSC/exosome trials with clear product and endpoint details.
Parkinson’s, epilepsy, spinal cord injury, ALS, Alzheimer’s disease, and adjacent CNS programs where cells are being tested as defined products.
Cell-replacement products, iPSC-derived systems, organoids, disease models, and manufacturing methods that shape the next generation of therapies.
Clinical records and papers where product identity, route, dose, and endpoints are concrete enough to follow over time.
Some stories need more room than a weekly capsule. These posts slow down around the trial design, source material, and scientific context.

The first randomized human test of injected iPSC-derived cardiomyocytes pairs early functional improvements with ventricular arrhythmias, immune recognition, and an unresolved graft-persistence question.

A ferret airway study follows donor basal cells from niche creation through engraftment, multilineage differentiation, CFTR current, and mucus transport before a living-animal test.
Read long postEach issue collects the week's most relevant trial records, papers, regulatory updates, and company developments in one place.
This issue covers the first randomized iPSC-cardiomyocyte trial, a Parkinson dopamine-cell study, two new hUC-MSC trials, hESC-derived stromal-cell safety testing, vascularized iPSC cell sheets, and airway basal-cell replacement.
This issue covers Rincell-1 in a cochlear-implant trial, acute and chronic stroke cell-therapy records, retinal RPE replacement, pediatric cerebral palsy MSCs, MultiStem MASTERS-2, and ALS iPSC-drug repurposing.
This issue covers stroke-focused MSC and secretome trial records, Parkinson cell-replacement comparison, human spinal interneurons in a rat SCI model, ALS extracellular vesicles, FTD iPSC-microglia, and hPSC differentiation quality.
A catch-up issue covering Parkinson and Huntington cell-replacement programs, iPSC spinal cord injury follow-up, chronic stroke trial design, retinal cell therapy, neonatal HIE MSCs, and CNS MSC records.
This week: FTD exosomes, two acute-stroke MSC trial records, retinal cell-therapy follow-up, Parkinson dopaminergic progenitors, Crohn’s extracellular vesicles, and a GMP-grade spinal cord injury paper.
This issue covers five-year NSI-566 follow-up, an Alzheimer’s exosome trial record, a small NMOSD MSC study, retinal replacement-cell development, iPSC disease models, and MSC product logic.
Longer notes on regulatory milestones, model-system papers, and clinical programs that remain useful after the weekly news cycle moves on.
Rincell-1 puts an otic neural progenitor-cell therapy into a first-in-human cochlear-implant trial, with safety, delivery, neural-health measurement, immunosuppression, and long follow-up all visible from the start.
B2065 enters acute ischemic stroke as a randomized placebo-controlled adipose-MSC trial, while the terminated MASTERS-2 record and TREASURE publication show why the field has to read stroke cell therapy carefully.
A Cell Stem Cell perspective argues that variation across Parkinson dopamine-cell therapy trials, patients, and graft sites may become one of the field’s central problems to solve.
A Science Translational Medicine paper uses human iPSC-derived V2a spinal interneurons to test whether transplanted cells can form a functional relay in an injured rat cervical spinal cord circuit.
STEM-PD, Kenai RNDP-001, and BlueRock bemdaneprocel show Parkinson dopaminergic cell replacement moving from isolated studies into a field readers can compare.
A Nature Medicine Phase 1 study reports 2-4 years of follow-up after direct iPSC-derived neural stem/progenitor cell transplantation in subacute cervical spinal cord injury.
hNPC01 long-term follow-up and a new CC-101 Phase 2 record show chronic stroke neural cell therapy moving toward longer observation and stronger controls.
Ruijin Hospital’s FTD trial record puts intranasal umbilical-cord MSC-derived exosomes into a three-arm Phase 1/2 design with placebo, two dose levels, and a disease-relevant clinical scale.
Two new acute ischemic stroke MSC trial records use randomized, masked, placebo-controlled designs, with different products, dose strategies, and endpoints.
A three-patient, five-year follow-up after direct NSI-566 neural stem cell implantation in chronic cervical spinal cord injury.
A recruiting Phase 1/2 trial record for intranasal umbilical-cord MSC-derived exosomes in mild-to-moderate Alzheimer’s disease.
Japan’s conditional approval and reimbursement path for Amchepry/raguneprocel marks a real step for iPSC-derived neural cell therapy.
A 2026 SNCA triplication midbrain organoid paper points to extracellular matrix remodeling before overt degeneration appears in the model.
iRegene’s NouvNeu001 has a U.S. Phase 1/2 trial record, sponsor-announced RMAT, and first U.S. dosing language.
Neurona’s rezanecel/NRTX-1001 has sponsor-reported open-label seizure-reduction data and a serious Phase 3 path.
The goal is to make each item readable now and still useful later, when results, follow-up, or regulatory updates arrive.
