The centrosome is a universal eukaryotic cell organelle that typically orchestrates the cytoskeleton and cell division. (helmholtz-munich.de)
Indeed, Akna mediates the delamination of the differentiating stem cells from their neuroepithelial niche, by orchestrating microtubule organizing center activity at the centrosome and recruiting proteins that stabilize adherence junctions to the centrosome thereby weakening the junctional complexes. (helmholtz-munich.de)
For example, some disease variants show significant overlap only with the neuronal centrosome proteome, and others, such as those of patients with periventricular heterotopia, only with the neural stem cell centrosome proteome. (helmholtz-munich.de)
This is the case for the splicing factor PRPF6 that we found at the centrosome specifically in neural cells and the mutation observed in a patients with periventricular heterotopia also caused some cells to remain at the ventricle in a preclinical model. (helmholtz-munich.de)

This is due to the nervous system's conserved basic architecture on the one hand, and on the other its lineage-specific structural diversity, which facilitates the specific comparison and possible homologization of neural structures and their respective sub-parts [ 3 ]. (biomedcentral.com)

This chapter focuses on reptiles and birds which undergo discoidal meroblastic cleavage, wherein the early cell divisions do not cut through the yolk of the egg but form a blastoderm. (oxfordsciencetrove.com)
