Embryo development after mitochondrial supplementation from induced pluripotent stem cells.

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
purposeThe purpose of this study was to evaluate the effects of mitochondrial supplementation (MS) on early embryonic development and to assess the safety of MS treatments using induced pluripotent stem cells (iPSCs) as the mitochondrial donor.
methodsIn this study, we evaluated the effect of MS on early embryonic development using induced pluripotent stem cells (iPSCs) as the donor. Mouse zygotes were injected with either mitochondria from iPSCs or a vehicle solution. Several parameters were evaluated, including the rates of blastocyst formation and implantation, the weight of E13.5 embryos and placentas, the distribution of the donor mitochondrial DNA (mtDNA), and the pattern of methylation in the differentially methylated regions (DMRs) of the H19 and Snrpn genes.
resultsWe found that neither the rates of blastocyst formation and implantation nor the weights of E13.5 embryos and placentas were significantly different between the MS and control groups. Additionally, the mtDNA from the iPSC donors could be detected in the muscle tissue of four fetuses and all placentas in the MS group. Finally, the methylation patterns of H19 and Snrpn DMRs remained unchanged by MS.
conclusionsiPSC-derived mtDNA was directly involved in the process of embryonic development after MS. No adverse effects were seen when using iPSCs as a mitochondrial donor, but it remains to be seen whether this method can improve embryonic development, especially in older mice.
