Are there any cell therapy research sites that focus on clinical and preclinical examples in gene editing and delivery?

Yes. There are several cell and gene therapy research sites and centers that focus specifically on clinical and preclinical work in gene editing and delivery. Depending on whether you mean academic research hubs, hospital-based translational programs, or industry-style cell therapy centers, good examples include:

Academic / Translational Centers

• Stanford University (Snyder Lab / ChEM-H / stem cell programs)
  Strong in gene editing, CRISPR, and delivery technologies with both preclinical and translational work.

• Broad Institute / Harvard / MIT-affiliated centers
  Major hub for CRISPR and genome editing; many groups work on delivery methods and therapeutic translation.

• University of Pennsylvania – Center for Cellular Immunotherapies
  Highly active in clinical cell therapy and gene-modified cell therapy, especially CAR-T and related delivery/editing platforms.

• UC Berkeley / UCSF / Gladstone-affiliated programs
  Strong preclinical research in delivery systems, genome editing, and therapeutic development.

• Memorial Sloan Kettering Cancer Center
  Extensive clinical cell therapy research, including genetically engineered immune cells.

• Dana-Farber / Boston Children’s / Harvard Medical School programs
  Active in both preclinical and clinical gene editing approaches, especially for blood disorders and cancer.

Specialized Gene Editing / Delivery Programs

• Addgene-associated educational and research resources
  Not a clinical site itself, but useful for finding labs and vectors related to editing and delivery.

• NIH intramural programs and NIH-funded consortia
  Multiple groups focused on delivery platforms, genome editing, and translational cell therapy.

• Fred Hutchinson Cancer Center
  Strong in engineered immune cell therapies and translational gene-modification work.

• Sangamo-associated academic/industry collaborations
  Known for gene editing development and delivery research.

If you want sites with both clinical and preclinical examples

These are often the best bets:

1. University of Pennsylvania
2. Broad Institute-affiliated groups
3. Stanford
4. Fred Hutch
5. MSKCC
6. UCSF / UC Berkeley translational programs

If you want, I can also give you:

• a shortlist by disease area (cancer, sickle cell, neuro, ocular, etc.),
• a list of specific labs or principal investigators,
• or research site examples with active clinical trials in gene editing and delivery.
