Introduction
Membrane Receptors Signaling between cells, cells and matrix, tissues, and systemically, is key to the developmental and differentiation process. While there are a large number of known methods of signaling these all fall into a few broad classes. Signaling also depends upon having an initial source for the signal and cells which can interpret the signal. To see how these mechanisms are employed you should look at embryo axes formation or the specific pages within each set of notes that refer to early development or system development (these pages are listed on Molecular Development homepage).
Some signals act internally (More? cell cycle) or over a short distance (between ajoining cells or to the cell itself), others act in a distance dependent manner (changing concentration of the signal will alter the response), others act by cascading (signaling from one cell to the next, to the next), and finally some signals act at a distance (between one tissue and a distant cell population).
Signaling in many cases precedes any observable change in cell shape and motility. Please note as an introduction the notes below have been extensively simplified. More details can be gained by clicking on specific links.

Mechanisms
- cell cycle- position in cell cycle, proliferative rate, post-mitotic
- time- position in cell cycle, cell death (apoptosis)
- adhesive interactions- cell/cell, cell/extracellular matrix
- transcription factors- Hox, bHLH, zinc finger,
- protein growth factors- VEGF, FGF, NGF, GDNF, TGFb
- steroidal growth factors- RA, TH,
- extracellular matrix proteins- Wnt7a, laminin, fibronectin
- ion signaling- calcium
