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

Organ shortage remains a major challenge in transplantation medicine. Interspecies blastocyst complementation is a promising approach to generate human organs in livestock hosts. However, getting xenogeneic donor cells to engraft and expand at early stages remains challenging. Here we identify an innate immune barrier, wherein host macrophages selectively recognize and eliminate viable xenogeneic donor cells. These events represent a form of phagoptosis and highlight a xenogeneic clearance process that we term xenophagocytosis. We identify the mechanism by which host macrophages selectively phagocytize xenogeneic donor cells: xenogeneic cells display elevated phosphatidylserine, an "eat-me" signal recognized by host macrophages through phagocytic receptor Axl. Xenophagocytosis blockade improves both rat and human donor chimerism in mouse embryos, indicating a conserved mechanism. These findings reveal potential mechanisms by which innate immune cells eliminate xenogeneic cells in early embryogenesis to preserve species integrity and offer improved strategies for generating human organs in livestock.
