Stem cell-based therapies have 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 currently sick and need a cure now? Perhaps not, as most studies and trials that deal with stem cells have shown limited and inconsistent therapeutic effectiveness. Furthermore, no research trials have revealed the stem cells’ precise mechanisms. Yet some people without the proper knowledge of the current progress of stem cell research still write and speak in public as if a miracle cure has already been found, while other people fear this research and aggressively protest all stem cell-based therapy. At present, researchers must accurately share their progress and knowledge about stem cells with the public in order to reduce the gap between the dream of miracle cures and the reality of medical science.
