Cell transplantation is a promising strategy for therapeutic treatment of ischemic heart diseases. In this study, cord blood mesenchymal stem cells (cbMSCs) and human umbilical vein endothelial cells (HUVECs) in the form of core-shell bodies (cbMSC/HUVEC bodies) were prepared to promote vascularization and restore heart functions in an experimentally-created myocardial infarction (MI) rat model. Saline, cbMSC bodies and HUVEC bodies were used as controls. In vitro results indicated that cbMSC/HUVEC bodies possessed the capability of heterotypic assembly of cbMSCs and HUVECs into robust and durable tubular networks on Matrigel. The up-regulated gene expressions of VEGF and IGF-1 reflected the robust expansion of tubular networks; in addition, the augmented levels of SMA and SM22 suggested smooth muscle differentiation of cbMSCs, possibly helping to improve the durability of networks. Moreover, according to the in vivo echocardiographic, magnetic resonance and computed-tomographic results, transplantation of cbMSC/HUVEC bodies benefited post-MI dysfunction. Furthermore, the vascularization analyses demonstrated the robust vasculogenic potential of cbMSC/HUVEC bodies in vivo, thus contributing to the greater viable myocardium and the less scar region, and ultimately restoring the cardiac function. The concept of core-shell bodies composed of perivascular cells and endothelial cells may serve as an attractive cell delivery vehicle for vasculogenesis, thus improving the cardiac function significantly.
This research output has an Altmetric Attention Score of 4. 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 21 October 2021.
All research outputs
#9,227,034
of 27,782,313 outputs
Outputs from Biomaterials
#4,932
of 11,142 outputs
Outputs of similar age
#76,164
of 259,001 outputs
Outputs of similar age from Biomaterials
#70
of 141 outputs
Altmetric has tracked 27,782,313 research outputs across all sources so far. This one has received more attention than most of these and is in the 66th percentile.
So far Altmetric has tracked 11,142 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one has gotten more attention than average, scoring higher than 54% of its peers.
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 259,001 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
We're also able to compare this research output to 141 others from the same source and published within six weeks on either side of this one. This one is in the 48th percentile – i.e., 48% of its contemporaries scored the same or lower than it.
