These findings suggest that members of this gene family may be good candidates to redundantly regulate the final stages of limb outgrowth and/or the remodeling process for digit separation.
The majestic final theme was organic outgrowth, not sentimental overkill.
While Dpp appears to regulate the forward extension of the anterior tubules, multiple further cues are likely to control other aspects of tubule outgrowth, including the final tip cell contacts.
When combined with the lack of detectable NPY expression in OECs in the ONL of homozygous Sox10 lacZ/lacZ embryos (Fig. 3E F ), our results are consistent with the previously proposed hypothesis (based on the timing of onset of NPY expression) that NPY secreted from inner-ONL OECs may be involved in the final stages of olfactory axon outgrowth towards glomerular targets (Ubink and Hökfelt, 2000).
Of course, Perry had expected this reaction, and secretly he welcomed it, for his friendship with Dick, whom he had scarcely known until his final few months at Lansing, was an outgrowth of, and counterbalance to, the intensity of his admiration for the chaplain's clerk.
To determine the NGF-stimulated axon outgrowth, recombinant mouse NGF (Sigma, final concentration of 25 ng/mL) or indicated conditioned-media (1 3 dilution) was added to the cultures for 48 h.
For clonal outgrowth at metastatic sites, as for final developmental cellular differentiation, EMT reversion such as mesenchymal to epithelial transition (MET) is required [ 76, 77].
So far, several studies on the role of NGF in PC12-27 cells were focused not on the mechanisms but only on the final effects of the neurotrophin, in particular neurite outgrowth and the expression of neuronal markers (Leoni et al., 1999; Schulte et al., 2010).
Kruskal-Wallis was used to analyze qualitative variables among these six cell lines Colonization and outgrowth at a distant site are the key final step in the process of metastatic cascade and, more importantly, colonization is the basis of organ specific metastasis.
