Generation and characterization of induced pluripotent stem cells from guinea pig fetal fibroblasts.
Article in Molecular medicine reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Induced pluripotent stem cells (iPS) represent an important tool to develop disease‑modeling assays, drug testing assays and cell‑based replacement therapies. The application of iPS in these fields requires the development of suitable animal models. Of the suitable species, guinea pigs are particularly important and offer significant advantages. Successful iPS generation has been accomplished in a number of species; however, it has not been reported in the guinea pig. The present study successfully generated iPS from guinea pigs (giPS) using single polycistronic virus transduction with mouse octamer‑binding transcription factor 4 (Oct4), sex determining region Y‑box 2 (Sox2), Kruppel‑like factor 4 and c‑Myc. The giPS cell lines were cultured in media containing leukemia inhibitory factor and guinea pig fibroblast cells were used as feeder cells. These cultures were expanded under feeder‑free culture conditions using ESGRO Complete Plus Clonal Grade medium containing 15% fetal bovine serum on gelatin‑coated dishes. The resultant cells had a normal karyotype, exhibited alkaline phosphatase activity and expressed the pluripotency markers Oct4, Sox2 and Nanog. The cells differentiated in vivo to form teratomas that contained all three germ layers of the tissue cells. The generation of giPS may facilitate future studies investigating the mechanisms underlying innate immunity, particularly for tuberculosis. These experiments provide proof of principle that iPS technology may be adapted to use the guinea pig as a model of human diseases.
