Since the musk deer distributed in the Dabie Mountains, Anhui was defined as Moschus moschiferus anhuiensis, its status has been disputed based on researches of morphology and ecology. This study further probed into its taxonomic status with principal components analysis (PCA) on skull measurements and mtDNA cytochrome b sequences (367 bp) analysis so as to clear its status. It is concluded that the figure and skull in Anhui musk deer are different from other species, and DNA divergence between it and other species is 6.24%-7.90%, which belongs to inter-specific difference. Thus, the study defines this musk deer as one distinct species, Moschus anhuiensis (Wang, Hu et al.)

First-in-human clinical trial for age-related macular degen- eration using iPSC-derived retinal pigment epithelium （RPE） cells was conducted in 2014, showing no serious adverse effects to date, including tumor formation. This appears to be attributable to relatively small number of transplanted cells, and distinct morphology of RPE cells; it might be relatively easy to minimize contamination of undifferentiated cells. However,
