| Abstract |
Normal human embryonic stem cells (hESCs) can develop neoplastic cancer stem cell (CSC) properties after coculture with transformed hESCs in vitro. In the present study, the influence of the tumor microenvironment on malignant transformation of bone marrow stromal cells (BMSCs) was studied after allografting a mixture of enhanced green fluorescent protein (EGFP)-labeled BMSCs and C6 glioma cells into the rat brain to understand the influence of the cellular environment, especially the tumor environment, on the transformation of grafted BMSCs in the rat brain. We performed intracerebral transplantation in the rat brain using EGFP-labeled BMSCs coinjected with C6 tumor cells. After transplantation, the EGFP-labeled cells were isolated from the tumor using fluorescence-activated cell sorting, and the characteristics of the recovered cells were investigated. Glioma-specific biomarkers of the sorted cells and the biological characteristics of the tumors were analyzed. The BMSCs isolated from the cografts were transformed into glioma CSCs, as indicated by the marked expression of the glioma marker GFAP in glioma cells, and of Nestin and CD133 in neural stem cells and CSCs, as well as rapid cell growth, decreased level of the tumor suppressor gene p53, increased level of the oncogene murine double minute gene 2 (MDM2), and recapitulation of glioma tissues in the brain. These data suggest that BMSCs can be transformed into CSCs, which can be further directed toward glioma formation under certain conditions, supporting the notion that the tumor microenvironment is involved in transforming normal BMSCs into glial CSCs. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 November 2015.
All research outputs
#14,828,686
of 22,833,393 outputs
Outputs from Molecular and Cellular Biochemistry
#1,257
of 2,305 outputs
Outputs of similar age
#214,467
of 386,452 outputs
Outputs of similar age from Molecular and Cellular Biochemistry
#11
of 29 outputs
Altmetric has tracked 22,833,393 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,305 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 42nd percentile – i.e., 42% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 386,452 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 29 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
