Mechanism of EC-EXOs-Derived THBS3 Targeting CD47 to Regulate BMSCs Differentiation to Ameliorate Bone Loss.

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
With the continuous increase of the elderly population and the deepening of population ageing in China, osteoporosis has gradually become one of the significant public health problems. Elucidating the pathophysiological mechanisms that induce osteoporosis and identifying more effective therapeutic targets is of great clinical significance. In this study, in vitro experiments demonstrated that endothelial cell exosomes (EC-EXOs) promoted osteogenic and inhibited adipogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). Aged and ovariectomy (OVX)-induced osteoporosis mice models injected with EC-EXOs confirmed that EC-EXOs delayed bone loss. Proteomic analysis revealed a key protein regulating the differentiation of BMSCs. Expression of THBS3 was significantly higher in EC-EXOs than in Human microvascular endothelial cells (HMEC-1). In vitro and in vivo experiments further validated that THBS3 promoted BMSCs' osteogenic differentiation, inhibited their adipogenic differentiation, and retarded bone loss. Computational biology analysis found that CD47 is a downstream target and potentially functional receptor in BMSCs that bind to THBS3. THBS3 treatment of BMSCs down-regulated the expression of CD47 in in vitro experiments. The aged/OVX models further confirmed that EC-EXOs can regulate the differentiation of BMSCs and delay the process of bone loss via the THBS3-CD47 axis. CD47 antibody may be a potential therapeutic agent for treating ageing-associated bone loss.
