Conclusion
Stem cell-based therapies hold incredible promise for the novel treatment, and perhaps even cure, of a wide range of diseases. However, can these promising results help people who are sick and looking for cures soon? Most studies and trials that deal with stem cells have showed limited and inconsistent therapeutic effectiveness. Furthermore, nobody has yet proven the mechanisms of stem cells during trials. Some people write and speak in public as if we find miracle cure without proper knowledge about current progress on stem cell research, while some people are so scared when they heard stem cell, so they aggressively stand up against stem cell based therapy. At present, it is very important role for researchers to share current progress of stem cell research and proper knowledge about stem cell with public without exaggeration in order to reduce the gap between dream and reality..
