Codifferentiation is a term used to describe the development and differentiation of cells that are closely associated with one another. It is a common process that occurs in many different organisms, including plants and animals. Synonyms for codifferentiation include co-development, co-differentiation, and co-differentiation. Other related terms include mutual differentiation and mutual development, which describe the process of two or more cells developing in a coordinated manner. Additionally, the term coregulation is often used to describe the control of gene expression and protein synthesis in cells that are undergoing codifferentiation. Overall, these terms all describe the process by which cells develop and differentiate in close association with each other.
