The relationship between cell density and pigment production has led some scientists to propose that this pigment is a secondary metabolite associated with "quorum sensing" gene expression patterns. Quorum sensing is a means by which bacterial cells communicate. Melanocyte biology and skin pigmentation. as MITF is believed to coordinately regulate the expression of pigment genes, although probably in conjunction with other context-dependent factors Cited by:
Anthocyanin Pigment Production in hp-2 Mutants. Although the phenotype of the hp-2 mutant is generally considered to be identical to that of the hp-1 mutant, it has not been examined in great detail. Therefore, we performed an analysis of hp-2 mutant characteristics by using hp-2 and hp-2 j mutant seedlings grown in the light and in the dark.. Consistent with the Cited by: PAX3 Cis-Regulatory Elements Transgenic mouse analysis demonstrated that the kb putative promoter region upstream of Pax3 directs gene expression in the dorsal neural tube, but is not sufficient to direct somite or craniofacial expression (Li et al., , Natoli et al., ).Deletion analyses suggested two distinct regions within the kb promoter were necessary for Pax3 expression .
In this chapter, there is a description of hematopoietic stem cells, maturation curve and their differentiation into myeloid cells, including phenotypes and transcription factors involved in this process. Further, we discuss myeloid maturation curve from myeloid precursor, monoblast, premonocyte to monocytes, and also monocytes subsets regarding their CD14 and CD16 expressions Author: Luciana Cavalheiro Marti, Nydia Strachman Bacal, Laiz CamerãoBento, Fernanda Agostini Rocha. Phenotypic heterogeneity arises among melanoma cells within the tumor as a consequence of (epi)genetic mutations, micro-environmental cues, and reversible changes within the cells. Over the last few years, several research groups studied distinct subpopulations in melanoma and framed their observations in different conceptual models to explain the phenotypic and functional diversity of melanoma by:

Control Mechanisms in the Expression of Cellular Phenotypes documents the proceedings of a symposium of the International Society for Cell Biology.
In progressively widening investigations, phenotypic expression has come to a critical focus not only in the developmental biology of animal and plant cells, but also in such fields as immunology, cytogenetics, enzymatic.
Thus, it is concluded that, under the conditions of cell culture, not only are some phenotypic specificities of NR maintained, but they appear de novo after cultur- ing the undifferentiated cells.
The expression Cited by: Abstract. Any in vitro analysis of differentiation should take into account three important factors. One is the artifactual nature of the in vitro conditions.
The very nature of the culture methodology creates an artifact. This is not meant to imply a deprecation of the study of a created artifact, for in many instances much useful information has been obtained from such by: Modulation is a reversible fluctuation within the already established range of determination; it is also the covert maintenance of the potentiality to express an original function.
Although many kinds of cells in vitro undergo changes of phenotypic expression, relatively few cell modulations have been examined closely.
Phenotypic changes in cell culture have an intrinsic interest and fascination as manifestations of unusual cell behavior Cited by: There are some basic differences between Bacteria, Archaea, and Eukaryotes in cell morphology and structure which aid in phenotypic classification and identification.

Pigment cells or chromatophores in the integument of amphibians are responsible for the characteristic colors of these animals. The chromatophores, marked both by their dendritic form and by the various colors imparted by their pigments, are clearly visible and provide qualitative and quantitative parameters of color change which can be.

Four first generation subclones, representing the four major morphological types encountered, were isolated: subclone A was composed exclusively of pigmented cells, and subclones B, C and D exclusively of unpigmented cells, B cells being clearly epithelial, C cells rather fibroblastic and D cells intermediate.
