Approximately 7% of the dividing cells that contribute to either the BC or EC lineage meet the criteria of true hemangioblasts, with one daughter cell becoming a BC and the other an EC.
Thus, ESCs fulfil the criteria of "true" stem cells and represent an "immortal" cell population, which in contrast to somatic cells of the body (under adequate culture conditions) may be maintained without signs of ageing.
This study was designed to establish the extensor carpi ulnaris groove (ECUG) as a reliable radiographic criterion for recognition of true neutral posteroanterior (PA) radiographs and to verify precise measurements of ulnar variance in a large cohort of patients.
However, the criterion for true positive selection indeed decreased the sensitivity of the microarray.
In general, by clinical criteria, sensitivity (proportion of true positive results) increases with more permissive clinical criteria, and specificity (proportion of true negative results) increases with more restrictive clinical criteria.
Younger and international users are particularly attracted to the mobile contact as the defining criteria of their true social network.
Recent experiments have established that the progenitor cell in the MM fulfils the criteria of a true committed stem cell in that is capable of self-renewing and of differentiating towards different types of nephron epithelia(Self et al. 2006; Boyle et al. 2008; Kobayashi et al. 2008).
They found that islands I, VI, and XII met the criteria of a true pathogenicity island, but no association was found between the presence of markers corresponding to these islands and invasiveness [ 20, 21].
Alternatively, WT CICs may relate to the more committed nephron progenitor cells, a population shown to self-renew and differentiate exclusively to nephron epithelia throughout nephrogenesis, fulfilling the criteria of a true committed stem cell (Kobayashi et al, 2008).
The performances of the methods were compared using the following criteria: call rate of true genotypes, accuracy of genotype prediction, and accuracy of genomic evaluations using the imputed genotypes.
