Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

AI and iPSCs: current applications for characterization and quality control
Background Reprogramming mechanisms Induced pluripotent stem cells (iPSCs) are created when adult somatic cells are subjected to a reprogramming protocol, designed to revive embryonic characteristics.
Article Description
Introduction: The prospect of therapeutic applications of the induced pluripotent stem cells (iPSCs) is based on their ability to generate virtually any cell type present in human body. Generation of iPSCs from somatic cells has opened up new possibilities to investigate stem cell biology, to better understand pathophysiology of human diseases, and to design new therapy approaches in the field of regenerative medicine. In this study, we focus on the ability of the episomal system, a non-viral and integration-free reprogramming method to derive iPSCs from somatic cells of various origin. Methods: Cells originating from neonatal and adult tissue, renal epithelium, and amniotic fluid were reprogrammed by using origin of replication/Epstein-Barr virus nuclear antigen-1 (oriP/EBNA-1)-based episomal vectors carrying defined factors. The iPSC colony formation was evaluated by using immunocytochemistry and alkaline phosphatase assay and by investigating gene expression profiles. The trilineage formation potential of generated pluripotent cells was assessed by embryoid body-mediated differentiation. The impact of additionally introduced factors on episome-based reprogramming was also investigated. Results: Reprogramming efficiencies were significantly higher for the epithelial cells compared with fibroblasts. The presence of additional factor miR 302/367 in episomal system enhanced reprogramming efficiencies in fibroblasts and epithelial cells, whereas the downregulation of Mbd3 expression increased iPSC colony-forming efficiency in fibroblasts solely. Conclusions: In this study, we performed a side-by-side comparison of iPSC colony-forming efficiencies in fibroblasts and epithelial cells transiently transfected with episomal plasmids and demonstrated that iPSC generation efficiency was highest when donor samples were derived from epithelial cells. We determined that reprogramming efficiency of episomal system could be further improved. Considering results obtained in the course of this study, we believe that episomal reprogramming provides a simple, reproducible, and efficient tool for generating clinically relevant pluripotent cells.
