Stem cells: Achievements and scandal

In 2014, scientists were able to differentiate stem cells into hepatocytes, keratinocytes, retinal cells, epithelial cells of the cornea. In September in Japan were started first clinical study with induced pluripotent stem cells (iPS), and in Europe - the Italian company received permission to use in corneal opacity stem cells from the edge of the cornea.
A group of Japanese scientists led by Haruko Obokata published in the journal "Nature» («Nature») their studies indicating that the cells in the transition state of STAP-Zelle ((from the English. Stimulus-triggered acquisition of pluripotency) allegedly pluripotent stem cells plyuripotentsiya which is caused by a simple external stimuli) -You can reach very easy with a simple application of physical force and the addition of citric acid. Unfortunately, the results of this study proved to be nothing more than artifacts, and criticized the study.
