Gender- and Age-Related Changes in the Spectrum of the Differentiation Potential of Individual Colonies of Stromal Precursors from Human Bone Marrow.

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
Bone marrow (BM) mesenchymal stromal progenitors that give rise to almost all mature cells in the hematopoietic niche were studied. We analyzed the differentiation spectrum of individual colony-forming units of fibroblast (CFU-F) clones depending on the age and gender of the donor. Individual CFU-F clones (n = 292) were obtained from the BM samples of 19 donors (11 men, 8 women). The concentration of monopotent adipogenic precursors in the BM of men was significantly higher than that in the BM of women (15% ± 5% versus 4% ± 2%). Moreover, the concentration of monopotent adipogenic precursors in women's BM had a clear negative correlation with age (R = -0.74), while, in men, it did not (R = -0.05). Younger donors of both genders had a higher proportion of monopotent adipogenic precursors; the proportion of precursors unable to differentiate increased markedly with age. All types of precursors revealed age- and gender-associated changes in the expression level of several genes. Both age and gender should be taken into account in studies concerning human stromal cells' regenerative abilities. Alterations in the stromal precursors' spectrum may impact the cellular composition of the bone marrow stromal microenvironment and explain the changes occurring in the regenerative potential with age and gender.
