Abstract
Transplantation-based cell therapy holds the potential to offer sustained and physiological repair for neurological diseases and injuries, which requires the integration of transplanted neurons into the neural circuits of the human brain. Recent studies involving transplantation of human pluripotent stem cell–derived neural progenitors into the brain of model animals reveal the remarkable capacity of grafted immature human neurons to mature, project axons in a long distance, and form both pre- and postsynaptic connections with host neurons, corresponding to functional recovery. Strikingly, this circuit integration depends largely on the identity of the transplanted cells and may be modified by external stimuli. This realization begs for enriched authentic target cells for transplantation and combination with rehabilitation for better therapeutic outcomes.
期刊介绍：
Current Opinion in Genetics and Development aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed.
In Current Opinion in Genetics and Development we help the reader by providing in a systematic manner:
1. The views of experts on current advances in their field in a clear and readable form.
2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.[...]
The subject of Genetics and Development is divided into six themed sections, each of which is reviewed once a year:
• Cancer Genomics
• Genome Architecture and Expression
• Molecular and genetic basis of disease
• Developmental mechanisms, patterning and evolution
• Cell reprogramming, regeneration and repair
• Genetics of Human Origin / Evolutionary genetics (alternate years)
