Non-human primates(NHPs) are similar with humans in their anatomy, physiology, genetics and neural functions, and in their cognition, emotions and social behavior. The NHP model has played an important role in the biomedical research, development of vaccines and drugs and new therapies for many *** advances in genome editing have generated NHP models for human diseases. Genome editing integrated with derivation of NHP pluripotent stem cells now provides an optimal resource to regenerate medicine.

A growing body of literature has shown that stem cells are very effective for the treatment of degenerative diseases in rodents but these exciting results have not translated to clinical practice. The difference results from the divergence in genetic, metabolic, and physiological phenotypes between rodents and humans. The high degree of similarity between non-human primates(NHPs) and humans provides the most accurate models for preclinical studies of stem cell therapy. Using a NHP model to understand the following key issues, which cannot be addressed in humans or rodents, will be helpful for extending stem cell applications in the basic science and the clinic. These issues include pluripotency of primate stem cells, the safety and efficiency of stem cell therapy, and transplantation procedures of stem cells suitable for clinical translation. Here we review studies of the above issues in NHPs and current challenges of stem cell applications in both basic science and clinical therapies. We propose that the use of NHP models, in particular combining the serial production and transplantation procedures of stem cells is the most useful for preclinical studies designed to overcome these challenges.

Cynomolgus macaques(Macaca fascicularis)belong to the genus *** are the most widespread nonhuman primate(NHP)and share a common ancestor with humans from about 25 million years ago(Kumar and Hedges,1998).Because of their phylogenetic proximity to humans,macaques are an attractive NHP research model for a wide range of biomedical research(Yan et al.,2011).
