Linking the Cell Cycle to Cell Fate Decisions

Novel Regulation of the Cell Cycle During Cell Fate Decisions in the Central Nervous System

Oxygen and Cell Fate Decisions

Molecular oxygen has been known to play a critical role in a wide range of biological processes including glycolysis, mitochondrial respiration, angiogenesis, pulmonary functions, and cardiovascular activities. An emerging theme has developed in recent years that oxygen has significant impact on embryonic development, maintenance of stem cells, and cellular differentiation or cell fate decision...

Cell cycle-dependent sequencing of cell fate decisions in Caenorhabditis elegans vulva precursor cells.

In Caenorhabditis elegans, the fates of the six multipotent vulva precursor cells (VPCs) are specified by extracellular signals. One VPC expresses the primary (1 degrees ) fate in response to a Ras-mediated inductive signal from the gonad. The two VPCs flanking the 1 degrees cell each express secondary (2 degrees ) fates in response to lin-12-mediated lateral signaling. The remaining three VPCs...

Cell Fate Decisions During Breast Cancer Development

During the formation of breast cancer, many genes become altered as cells evolve progressively from normal to a pre-malignant to a malignant state of growth. How mutations in genes lead to specific subtypes of human breast cancer is only partially understood. Here we review how initial genetic or epigenetic alterations within mammary epithelial cells (MECs) can alter cell fate decisions and put...

Dwelling on T Cell Fate Decisions

Defining determinants of T cell fate is central to understanding adaptive immunity and the design of effective vaccines. Tubo et al. demonstrate that intrinsic properties of T cell receptor signaling dictate whether CD4 T cells adopt predominantly type 1 helper or follicular helper T cell phenotypes in response to bacterial or viral infection.
