Nuclear transplantation, cell fusion, and induced pluripotent stem cell studies have revealed a surprising degree of plasticity in mature mammalian cell fates. Somatic cell reprogramming also has been achieved more recently by the directed conversion of nonneuronal somatic cells, such as skin fibroblasts, to neuronal phenotypes. This approach appears particularly applicable to the in vitro modeling of human neurologic disorders. Central nervous system neurons are otherwise difficult to obtain from patients with neurologic disorders; however, nonhuman models may not reflect patient pathology. Somatic cell reprogramming may afford models of nonfamilial "sporadic" neurologic disorders, which are likely caused by multiple interacting genetic and nongenetic factors. Directed somatic cell reprogramming, which does not pass through typical in vivo developmental stages, toward many mature neuronal phenotypes has now been described. This article reviews the field and discusses the potential utilities of such models, such as for the development of personalized medicine strategies.
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 15 April 2014.
All research outputs
#20,656,820
of 25,374,647 outputs
Outputs from Biological Psychiatry
#5,787
of 6,597 outputs
Outputs of similar age
#245,128
of 321,108 outputs
Outputs of similar age from Biological Psychiatry
#62
of 75 outputs
Altmetric has tracked 25,374,647 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 6,597 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 18.6. This one is in the 5th percentile – i.e., 5% 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 321,108 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 75 others from the same source and published within six weeks on either side of this one. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
