Macrophage colony-stimulating factor pretreatment of bone marrow progenitor cells regulates osteoclast differentiation based upon the stage of myeloid development.

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
Osteoclasts (OCs) are large, multinucleated bone resorbing cells originating from the bone marrow myeloid lineage, and share a common progenitor with macrophages and dendritic cells. Bone marrow cells (BMCs) are a common source for in vitro osteoclastogenesis assays but are a highly heterogeneous mixture of cells. Protocols for in vitro osteoclastogenesis vary considerably thus hindering interpretation and comparison of results between studies. Macrophage colony-stimulating factor (M-CSF) pretreatment is commonly used to expand OC progenitors (OCPs) in BMC cultures before in vitro differentiation. However, the failure of osteoclastogenesis of M-CSF primed bone marrow myeloid blasts has been reported. In this study, we used a simple method of differential adherence to plastic to enrich OCP from mouse BMCs. We found that M-CSF pretreatment of plastic-adherent BMCs (adBMCs) increased the number of CD11b-F4/80+ macrophages and decreased the number of CD11b+ monocytes resulting in decreased OC formation. M-CSF pretreatment of purified c-Kit+ progenitors weakly inhibited OC formation, whereas M-CSF pretreatment of purified c-Kit-CD11b+ progenitors promoted the formation of large OC. M-CSF pretreatment increased the proliferation of both purified c-Kit+ and c-Kit-CD11b+ cells and increased the percentage of CD11b-F4/80+ cells from c-Kit+ progenitors. In addition, M-CSF pretreatment increased the percentage of CD11b+ F4/80- cells from purified c-Kit-CD11b+ cells. M-CSF pretreatment increased the percentage of CD14 + CD16 + intermediate monocytes and subsequent OC formation from human 2adBMCs, and increased OC formation of purified CD14 + cells. Together, these results indicate that in vitro OCP expansion in the presence of M-CSF and bone marrow stromal cells is dependent upon the developmental stage of myeloid cells, in which M-CSF favors macrophage differentiation of multipotent progenitors, promotes monocyte maturation and supports differentiation of late-stage OCP cells.
