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

backgroundConsidering the limitations in isolating Bone Marrow Mesenchymal Stem Cells (BMSCs), alternate sources of Mesenchymal Stem Cells (MSCs) are being intensely investigated. This study evaluated dental pulp MSCs (DP-MSCs) isolated from orthodontically extracted premolar teeth from a bone tissue engineering perspective.

methodsMSCs isolated from premolar teeth pulp were cultured and studied using BMSCs as the control. Flow cytometry analysis was performed for the positive and negative MSC markers. Multilineage differentiation focusing on bone regeneration was evaluated by specific growth induction culturing media and by alkaline phosphatase (ALP) activity. Data were compared by repeated measurement analysis of variance and Student's t-test at a

resultsProliferation rate, population doubling time, and colony formation of DP-MSCs were significantly higher (p < 0.001) than BMSCs. More than 85% of DP-MSCs expressed CD44, CD73, CD90, CD105, and CD166. Negative reaction was found for CD11b CD33, CD34, and CD45. Positive reaction was displayed by 7.2% of cells for early MSC marker, Stro-1. Both the cell populations differentiated into adipogenic, osteogenic, and chondrogenic lineages, with adequate ALP expression.

conclusionBecause DP-MSCs from orthodontic premolars hold a neural crest/ectomesenchymal ancestry, its prudent growth characteristics and multilineage differentiation open up exciting options in craniofacial tissue engineering.
