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

backgroundHuman embryonic stem cells (hESCs) can be efficiently and reproducibly directed into cardiomyocytes (CMs) using stage-specific induction protocols. However, their functional properties and suitability for clinical and other applications have not been evaluated. METHODS AND

resultsHere we showed that CMs derived from multiple pluripotent human stem cell lines (hESC: H1, HES2) and types (induced pluripotent stem cell) using different in vitro differentiation protocols (embryoid body formation, endodermal induction, directed differentiation) commonly displayed immature, proarrhythmic action potential properties such as high degree of automaticity, depolarized resting membrane potential, Phase 4- depolarization, and delayed after-depolarization. Among the panoply of sarcolemmal ionic currents investigated (I(Na)(+)/I(CaL)(+)/I(Kr)(+)/I(NCX)(+)/I(f)(+)/I(to)(+)/I(K1)(-)/I(Ks)(-)), we pinpointed the lack of the Kir2.1-encoded inwardly rectifying K(+) current (I(K1)) as the single mechanistic contributor to the observed immature electrophysiological properties in hESC-CMs. Forced expression of Kir2.1 in hESC-CMs led to robust expression of Ba(2+)-sensitive I(K1) and, more importantly, completely ablated all the proarrhythmic action potential traits, rendering the electrophysiological phenotype indistinguishable from the adult counterparts. These results provided the first link of a complex developmentally arrested phenotype to a major effector gene, and importantly, further led us to develop a bio-mimetic culturing strategy for enhancing maturation.

conclusionsBy providing the environmental cues that are missing in conventional culturing method, this approach did not require any genetic or pharmacological interventions. Our findings can facilitate clinical applications, drug discovery, and cardiotoxicity screening by improving the yield, safety, and efficacy of derived CMs.
