[Retracted] MicroRNA‑675 inhibits cell proliferation and invasion in melanoma by directly targeting metadherin.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the western blotting data shown in Fig. 5A and the cell migration and invasion assay data shown in Fig. 5C were strikingly similar to data appearing in different form in other articles by different authors at different research institutes, several of which have been retracted.

Injectable platelet rich fibrin facilitates hair follicle regeneration by promoting human dermal papilla cell proliferation, migration, and trichogenic inductivity.

Hair follicle regeneration has been successful in mice but failed in human being for years. Dermal papilla cells, a specialized mesenchymal stem cell derived from dermal papilla within hair follicles, is considered the key cells for hair follicle regeneration function as both regeneration initiator and regulator. Injectable platelet rich fibrin (i-PRF), a novel biomaterial rich in a variety of growth factors and three-dimensional scaffolds, has shown promising effects on tissue regeneration.

MicroRNA‑675 inhibits cell proliferation and invasion in melanoma by directly targeting metadherin.

Melanoma is derived from melanocytes and accounts for ~80% of skin cancer-associated fatalities worldwide. The dysregulation of microRNAs (miRNAs/miRs) is involved in the development and progression of melanoma. Therefore, miRNAs may be novel diagnostic or prognostic biomarkers and promising therapeutic targets in the treatment of patients with melanoma.
