Effects of mesenchymal stem cells from different sources on the biological functions of multiple myeloma cells.
Article in Stem cell research & therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe therapeutic benefits of mesenchymal stromal cells (MSCs) are largely dependent on paracrine factors, but the supernatants of the different MSCs may have different effects on multiple myeloma (MM) cells. Therefore, this study compared supernatants of bone marrow-derived mesenchymal stromal cells (BM-MSCs) with umbilical cord wharton's jelly's mesenchymal stem cells (UC-WJ MSCs) in different states (non-senescent and replicative senescence) on the MM cells.
methodsWe extracted human BM-MSCs and UC-WJ MSCs in vitro and used H
resultsWe successfully isolated and identified BM-MSCs, UC-WJ MSCs, and SMSCs. When concentrated supernatants from BM-MSCs, UC-WJ MSCs, senescent BM-MSCs (SBM-MSCs), senescent UCWJ MSCs (SUC-WJ MSCs) were used to treat MM cells, BMMSCs and SBM-MSCs supernatants promoted the proliferation of MM cells, with a more pronounced effect by SBM-MSCs. UC-WJ MSCs and SUC-WJ MSCs supernatants inhibited the viability and proliferation of MM cells. BM-MSCs and SBM-MSCs supernatants increased the proportion of MM cells in the S-phase, with the effect of SBM-MSCs being more evident. UC-WJ MSCs and SUC-WJ MSCs supernatants arrested MM cells in the G0/G1 phase. BM-MSCs and SBM-MSCs supernatants enhanced the migration and tumor stemness of MM cells, with SBMMSCs having a more dramatic effect. UC-WJ MSCs and SUC-WJ MSCs supernatants inhibited the migration and tumor stemness of MM cells, with UC-WJ MSCs having a more inhibitory effect. IL-6 and VEGFA expression correlated negatively with the survival of patients with MM according to online database analysis, in addition, we found that the expression of IL-6 and VEGFA was higher in MM patients through GEO database analysis. BM-MSCs and SBM-MSCs supernatants treatment increased the expression of IL-6 and VEGFA on MM cells, while UC-WJ MSCs and SUC-WJ MSCs supernatants inhibited their expression. Signal pathway validation showed that the biological function of MSCs in MM is closely related to the PI3K/AKT/NF-κB pathway.
conclusionThe supernatants of BM-MSCs promote the proliferation of MM cells, On the contrary, the supernatants of UC-WJ MSCs inhibit MM cell proliferation. We observed that MSCs from different sources and different states have contrasting biological functions in MM cells. Furthermore, this research was provided to the optimal cancer gene therapy vector for MM was UC-WJ MSCs, even UC-WJ MSCs was in the state of senescence.
