Nature, 1983
Mating type interconversion has a precise lineage which serves to minimize the time taken for yeast cells to achieve the diploid state. The HO gene either encodes or regulates an endonuclease which initiates the interconversion process. Expression of this gene is switched on during the G1 phase of mother cells and not at all during the cell cycle of ...

Stability of Regulatory T-cell Lineage

2011
Regulatory T (Treg) cells expressing the transcription factor Foxp3 constitute a unique T-cell lineage committed to suppressive functions and play a central role in maintaining self-tolerance and immune homeostasis. While their differentiation state is remarkably stable in the face of various perturbations from the extracellular environment, recent ...

Cell Lineage and Differentiation in Drosophila

1978
Embryonic differentiation is usually monitored by the appearance of cell, or tissue-specific enzymes or their products or structural proteins. These phenotypic traits correspond to the activities of specific genes, and therefore, in the long run, differentiation has to be explained in terms of selective gene activities.
