Prolonged maintenance of hematopoietic stem cells that escape from thrombopoietin deprivation.
Article in Blood, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Hematopoietic stem cells (HSC) rarely divide, rest in quiescence, and proliferate only upon stress hematopoiesis. The cytokine thrombopoietin (Thpo) has been perplexingly described to induce quiescence and promote self-renewal divisions in HSCs. To clarify the contradictory effect of Thpo, we conducted a detailed analysis on conventional (Thpo-/-) and liver-specific (Thpofl/fl;AlbCre+/-) Thpo-deletion models. Thpo-/- HSCs exhibited profound loss of quiescence, impaired cell cycle progression, and increased apoptosis. Thpo-/- HSCs also exhibited diminished mitochondrial mass and impaired mitochondrial bioenergetics. Abnormal HSC phenotypes in Thpo-/- mice were reversible after HSC transplantation into wild-type recipients. Moreover, Thpo-/- HSCs acquired quiescence with extended administration of a Thpo receptor agonist, romiplostim, and were prone to subsequent stem cell exhaustion during competitive bone marrow transplantation. Thpofl/fl;AlbCre+/- HSCs exhibited similar stem cell phenotypes but to a lesser degree compared with Thpo-/- HSCs. HSCs that survive Thpo deficiency acquire quiescence in a dose-dependent manner through the modification of their metabolic state.
