Moreover, these cells are able to obtain pigmentation, a typical characteristic of functional RPE cells.
Moreover, they were able to obtain pigmentation upon activation of Retinoic acid (RA) and Sonic Hedgehog (SHH) signaling pathways.
Pigmentation genes identified in teleosts were obtained from pigmentation mutant collections in zebrafish (Haffter et al. 1996; Kelsh et al. 1996; Odenthal et al. 1996) available from the Zebrafish Model Organism Database (ZFIN; http://zfin.org) and in medaka (Kelsh et al. 2004).
For analysis of structuring of tannin phenotypes, we obtained testa pigmentation data (n = 14,785) in world sorghum collections from the Germplasm Resource Information Network.
Tissue samples containing visible purple pigmentation were obtained from roots of the 70349 mapping population.
Genes underlying skin pigmentation were obtained from a study by Myles and colleagues [ 82].
In all transgenic lines obtained, flies had weak pigmentation of the wing and body cuticle that corresponded to the basal level of yellow transcription in the absence of enhancers (grade 2) or to its weak stimulation (grade 3).
The frequency of sphere formation was 0.16±0.03%, (N = 3) similar to results obtained with size and pigmentation-based sorts.
However, of the adult fish we obtained, 10% displayed some melanophore pigmentation, demonstrating that some of the small set of melanophore stem cells (Dooley et al., 2013a) were affected in these cases (Fig. 2E,F, Table 1).
We describe the histochemical, ultrastructural, and microanalytical features of a skin biopsy specimen obtained from a patient with chlorpromazine pigmentation.
A resulting photoaging status of each subject was, therefore, obtained by adding both "wrinkles" and "pigmentation" grades.
