Optimizing a serum-free/xeno-free culture medium for culturing and promoting the proliferation of human dental pulp stem cells.
Article in Stem cell investigation, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundDental pulp stem cells (DPSCs) hold great promise for utilization in tissue repair and regenerative medicine. Routinely, culture media used for culturing stem cells are supplemented with animal serum for promoting growth and successful maintenance of stem cells. However, there is a growing demand for optimizing a well-defined culture media that could safely increase the efficacy and reproducibility of the cultured cells. In this study, we aimed at optimizing a serum-free/xeno-free culture medium.
methodsA cocktail of various supplements intended to enrich DPSCs proliferation in defined concentrations was designed. It consisted of recombinant human basic fibroblast growth factor (hbFGF), insulin transferrin selenium (ITS), ascorbic acid (vitamin C), Beta mercaptoethanol and cholesterol. The effect of this optimized media on the proliferation of DPSCs was assessed by MTT assay and flow cytometric analysis (FACS) of early apoptotic marker annexin V. Expression of stemness-related genes (OCT4, SOX and NANOG) was assessed by qRT-PCR.
resultsProliferation results by MTT illustrated a significant increase in the proliferation rate of DPSCs cultured in the proposed media. FACS analysis of annexin V expression was nil. Expression of OCT4, SOX and NANOG genes was also up-regulated.
conclusionsThe proposed combination of supplements utilized in the proposed culture media successfully increased the proliferation potential of DPSCs in addition to enhancing the stemness properties. Thus, it can be considered a promising and safe substitute to traditional animal derived supplements like fetal bovine serum (FBS).
