Cell fate decisions and patterning in the vertebrate retina: the importance of timing, asymmetry, polarity and waves

Current Opinion in Neurobiology
Jarema Malicki


The differentiation of distinct cell populations in the retina is a multi-step process that involves cell cycle exit, migration, and dramatic changes of cell morphology. All these steps are tightly controlled by multiple regulatory pathways, which involve both cell-autonomous networks of transcription factors and cell-cell signaling events. Additional regulatory inputs into cell fate decisions have been recently suggested: accumulating evidence shows that the timing of cell cycle exit, the orientation of the mitotic spindle during the last cell division, and the polarity of neuronal progenitor cells could play important roles in cell fate determination.

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.

Cell Fate Specification

Cell fate specification is determined by complex signal transduction pathways including Notch and the Sonic hedgehog signaling pathway. Here is the latest research on regulation of cell fate determination.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins. Discover the latest research on cadherins and catenins here.
