Specialization is a method of production whereby an entity focuses on the production of a limited scope of goods to gain a greater degree of efficiency. Many countries, for example, specialize in producing the goods and services that are native to their part of the world, and they trade for other goods and services. This specialization is, therefore, the basis of global trade, as few countries have enough production capacity to be completely self-sustaining.

Cell-to-cell communication is particularly important in regulating gene expression during the embryonic development.
Cells in the developing embryo are constantly communicating with their neighbors. The molecules used by them in sending and receiving signals are crucial for normal embryogenesis. Various intracellular signaling pathways have been discovered, some of which are activated in response to secreted growth factors.
However, a few important signaling pathways are used often during embryonic development to regulate various cellular processes that shape the developing embryo.
Embryonic development is marked by the thorough regulation of cellular functioning so that the cells proliferate, migrate, differentiate, and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, as well as on the activities of signaling pathways, which coordinate the cell interactions leading to organogenesis.
