1 · What the graph read from it

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.

2 · The registry

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

Given the limited availability of tissue, especially brain tissue, for neurological diseases and disorders research, the development of alternative biological tools for investigations of underlying molecular and genetic mechanisms is imperative. One important resource for this task is the large repositories that bank immortalized blood cells (i.e. lymphoblastoid cell lines; LCLs) from affected individuals and their unaffected family members. These repositories document demographic, phenotypic, and, in some cases, genotypic information about the donors and thus provide a ready-made sample source for hypothesis testing. Importantly, patient-specific LCLs can be used to generate induced pluripotent stem cells (iPSC) that, in turn, can be used to create specific cell types for use in mechanistic studies. To investigate this concept further, LCLs from two males (proband and sibling) were obtained from one such repository, the Autism Genetics Resource Exchange (AGRE), and iPSCs were generated by transfection with Epi5 Episomal iPSC reprogramming plasmids. Characterization of the resultant cell lines by PCR, RT-PCR, immunocytochemistry, karyotyping, and the Taqman® human pluripotent stem cell Scorecard™ Panel, was used to provide evidence of endogenous pluripotency and then to evaluate the trilineage potential of four representative clones. Results indicated that all four iPSC lines were initially pluripotent and displayed the trilineage potential predictive for successful differentiation to mesoderm, endoderm, or ectoderm-derived cell types. Compared to other published protocols, this study details a somewhat simplified approach, used here specifically for the generation and characterization of induced pluripotent stem cells from well-characterized and banked LCLs.
