Mechanism of umbilical cord mesenchymal stem cells in the expansion of umbilical cord blood-derived hematopoietic stem cells in vitro.
Review in The Journal of international medical research, 2025. 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
The methodologies and applications of ex vivo expansion of umbilical cord blood cells represent a significant research domain, primarily owing to the distinctive characteristics of these cells and their prospective uses in regenerative medicine and hematopoietic stem cell transplantation. We searched PubMed and Web of Science using the terms "umbilical cord blood cells," "cytokine," "haematopoietic cells," "umbilical cord mesenchymal stem cells," "in vitro expansion," and "microenvironment," and the selected literature was organized and analyzed. We present a narrative review of the mechanisms by which umbilical cord mesenchymal stem cells enhance the in vitro expansion of umbilical cord blood-derived hematopoietic stem cells, focusing on three primary aspects: secretion of diverse cytokines to replicate the natural hematopoietic microenvironment, transmission of critical signals via direct cell-to-cell contact, and exertion of immunomodulatory effects to alleviate environmental stress. Although these processes can significantly promote the proliferation and survival of hematopoietic stem cells, the challenge of concurrently preserving the long-term stemness of these cells in an in vitro environment remains a critical issue for future research.
