Mechanisms for removal of developmentally abnormal cells: cell competition and morphogenetic apoptosis.

Abstract excerpt

Various cell differentiation signals are tightly linked with apoptotic signals. For example, as a result of somatic mutations, cells within a developing field occasionally receive an altered level of morphogenetic signaling that gives rise to an abnormal cell type. However, these developmentally abnormal cells are frequently removed by activating apoptotic signals. Although such phenomena are crucial for assuring...
