                    1. Stem cells
                      1. Therapeutic use
                        1. International mindeness
                          1. National governments are influenced by local, cultural and religious traditions that impact on the work of scientists and the use of stem cells in therapy

                              2. Stem cell research has depended on the work of teams of scientists in many countries who share results thereby speeding up the rate of progress
                                1. Application
                                  1. Treat Stargardt’s disease
