Microvascular mural cells (MMCs), comprising pericytes and microvascular smooth muscle cells, are of increasing interest in multiple fields of research for their plasticity and their organotypic functional roles in microvascular homeostasis and disease. They have been described as a heterogeneous cell population constituting a continuum of cell phenotypes along the microvascular bed with vascular smooth muscle cells (VSMCs) at one end of the spectrum and pericytes at the other end. MMC organotypic subpopulations have been suggested to function in a tissue-context-dependent manner, thereby contributing to organ-specific functional roles. However, the phenotypic and organotypic heterogeneity as well as their origin and marker identification are hitherto poorly defined. Here we review recent work and emerging concepts regarding MMC phenotypic and organotypic heterogeneity and their functional plasticity in health and disease.
This research output has an Altmetric Attention Score of 1. 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 24 July 2018.
All research outputs
#20,663,600
of 25,382,440 outputs
Outputs from Trends in Cell Biology
#1,834
of 1,956 outputs
Outputs of similar age
#343,693
of 449,622 outputs
Outputs of similar age from Trends in Cell Biology
#19
of 20 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,956 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.2. This one is in the 1st percentile – i.e., 1% 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 449,622 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 20 others from the same source and published within six weeks on either side of this one. This one is in the 5th percentile – i.e., 5% of its contemporaries scored the same or lower than it.
