Preparation of Patient Autologous Induced Pluripotent Stem Cell-derived Retinal Cells for AMD

One or more types of somatic cells will be collected from every participant by collecting approximately 100~500 ml of midstream urine, 20~30 ml of peripheral blood, skin biopsies (3mm), conjunctiva biopsies (5mm×5mm), etc. Then, these somatic cells will be used to prepare patient autologous induced pluripotent stem cell-derived retinal cells for the cell therapy of age-related macular degeneration patient.

Inclusion criteria

• Voluntary as test subjects, informed consent, regular follow-up on time;
• Voluntary as test subjects to join the associated clinical research on autologous iPSC-derived retinal cell therapy for AMD (ethical approval and informed consent documents will be applied and signed separately);
