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

The use of cell therapies in bone reconstruction has been the subject of extensive research. It is known that human bone marrow stromal cell (HBMSC) cultures contain a population of progenitor cells capable of differentiation towards the osteogenic lineage. In the present study, the correlation between the in vitro osteogenic potential of HBMSC cultures and their capacity to form bone in vivo was investigated. HBMSC cultures were established from 14 different donors. Fourth passage cells were examined for the expression of alkaline phosphatase (ALP), procollagen I (PCI) and osteopontin (OP), through flow cytometry and the effect of the osteogenic differentiation factor dexamethasone (Dex) on this expression was evaluated. In addition, the capacity of the cultures to induce in vivo bone formation was analysed by culturing the cells on porous hydroxyapatite (HA) scaffolds followed by subcutaneous implantation of these constructs in nude mice. Results showed expression of PCI, OP and ALP in all cultures, irrespective of the presence of Dex in the culture medium. Dex failed to have a significant effect on the expression of PCI and OP but it induced a consistent increase in the relative amount of cells expressing ALP. Nevertheless, although in vitro testing clearly indicated osteogenic potential in all cultures, HBMSC from six of the 14 tested donors did not form bone in vivo. The results, therefore, demonstrate that neither the expression of PCI, OP and ALP nor the absolute increase in Dex-stimulated ALP expression can as yet be used as predictive markers for in vivo bone formation by HBMSC. However, preliminary data indicate that not the absolute, but the relative increase in the percentage of ALP expressing cells caused by Dex stimulation may be related to the ability of the HBMSC to form bone.
