The Editor-in-Chief has retracted this article. Concerns were raised regarding the source of the stem cells described in this article and whether the coordination polymers enhance stem cell differentiation. The article also shows significant text overlap with a previously published and now retracted article by different authors [1]. The article also shows evidence of authorship manipulation. Additionally, the first author has contacted the journal to request the retraction of the article. The first author has stated that the article was written by a third-party company. The first author has also stated that the corresponding author was not aware of the submission and publication of this article and that they do not know the other two authors. The Editor-in-Chief therefore no longer has confidence in the results and conclusions of this article.
