Plants and some animals are characterized by the system of regeneration and repair of damage in their bodies. Is it possible to use this feature for regeneration of human organs and regenerated nervous system, neurons, etc?
interesting questions I have read this article in title "Humans may soon regenerate damaged body parts like salamanders" if you read , may be answer your question.
The technology for studying and implementing regeneration has improved steaduly in the last years. However, so far it is not possible. To-date it remains a most serious research program.
A difficult hurdle the issue faces are the religious set of prohibitions that many Univesities, etc. encounter; especifically working with stem cells - which remains the main track for the investigation on the field.
Coping with the advancement in technology and the hurdles from religion and politics in many places can ensure in a foreasble future the possibility of regeneration, self-repair, and the like - of organs, tissues, etc.
You are asking a question about tissue engineering and regenerative medicine. If you are new to this field I would suggest you watch Anthony Atala's TED talk on the subject: https://www.ted.com/talks/anthony_atala_growing_organs_engineering_tissue
Basically, hollow organs are clinically viable (bladder, blood vessel) but the inability to perfuse large engineered organs or engineer vasculature within grown organs is the roadblock for greater success. I would also direct you to read Laura Niklason's paper on growing lungs for transplant: http://www.sciencemag.org/content/329/5991/538.short
