The Critical Functions of FGF2, LIF and IGF1 in the Improvement of In Vitro Embryo Production.
Review in Biomolecules, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In vitro embryo production (IVP) has emerged as a crucial tool in assisted reproduction and animal biotechnology. A key factor in this process is in vitro oocyte maturation (IVM), a critical process preceding fertilization that directly influences embryo quality. FLI supplementation, composed of fibroblast growth factor (FGF2), leukemia inhibitory factor (LIF), and insulin-like growth factor 1 (IGF1), has been shown to facilitate the IVM process to mimic essential aspects of in vivo oocyte development, and therefore, promote higher rates of oocyte maturation, embryonic viability, blastocyst formation, and improve the number of live animals born after embryo transfer. Individually or together, these components participate in signaling pathways that are crucial for improving oocyte competence and early embryo development. This review highlights the individual and combined roles of FGF2, LIF, and IGF1 in maturation and embryo culture medium, their influence on subsequent embryonic development, and their signaling pathways. Additionally, the incorporation of antioxidants and amino acids as supplementary components in combination with FLI is explored as a strategy to mitigate oxidative stress and enhance metabolic support during IVM and embryo culture. Together, these elements can significantly improve IVP outcomes, providing a potential pathway for optimizing the efficiency of embryo production in various species.
