Potential role of centrioles in determining the morphogenetic status of animal somatic cells

Centrioles (diplosome) are the most likely unit that can fully regulate the processes of irreversible differentiation, determination and modification of the morphogenetic status. It may contain differently encoded RNA molecules stacked in a definite order. During mitosis, these RNA molecules are released one by one into the cytoplasm. In the presence of reverse transcriptase and endonuclease, RNA can be embedded in nuclear DNA. This process presumably changes the status of repressed and potentially active genes and, subsequently, the morphogenetic status of a cell.
