Protocol of Human Primordial Germ Cell-like Cell Generation from Pluripotent Stem Cells in 2D and 3D Culture Systems.
Article in Biology, 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
Because human infertility can arise from genetic, molecular, cellular, anatomical, and endocrine abnormalities, in vitro gametogenesis has become an important area of reproductive research. New developing technology involving the generation of human primordial germ cell-like cells (hPGCLCs) from induced pluripotent stem cells (hIPSCs) might assist with understanding early germ cell development (specification, migration, gametogenesis, and epigenetic reconstitution), as well as provide a solution for infertility and hereditary disorders. Given that human primordial germ cells (PGCs) are still not well characterized at a molecular level, we present a practical workflow to robustly and efficiently induce hPGCLCs from human pluripotent stem cells (hPSCs) XX and XY cell lines. This protocol describes the hPGCLC specification of hPSCs through sequential induction with Activin A for 2 days and BMP4 for 6 days in 2D and 3D culture systems. Induction of hPSCs into hPGCLCs demonstrated expression of early primordial germ cell markers, including PRDM1, NANOS3, DAZL, STELLA, SOX17, SSEA1, and cKIT, on the 8th day of hPGCLC generation. We described the protocol for generating early hPGCLCs, which provides an opportunity for further investigations into maturation into late germ cells and a chance to overcome a meiotic block to obtain haploid gametes in vitro.
