Question

Signal transduction pathways are important mechanisms for cell-to-cell communication in multicellular organisms. How do the target cells typically respond when they receive signals from neighboring cells during very early stages of embryo development?

Answer 1

Target cells typically respond to signals from neighboring cells during very early stages of embryo development by initiating a cascade of biochemical reactions that lead to changes in gene expression. These changes can result in the differentiation of the target cell into a specific cell type, the migration of the cell to a new location, or the activation of specific proteins that control cell growth and division.
