Centrioles without microtubules: a new morphological type of centriole [PDF]
Biology Open, 2018 The centrosome is the organizing center of microtubules in the cell, the basis for the origin of cilia and flagella and a site for the concentration of a regulatory proteins multitude.

The Centriole’s Role in Miscarriages [PDF]
Frontiers in Cell and Developmental Biology, 2022 Centrioles are subcellular organelles essential for normal cell function and development; they form the cell’s centrosome (a major cytoplasmic microtubule organization center) and cilium (a sensory and motile hair-like cellular extension).

Insights into centriole geometry revealed by cryotomography of doublet and triplet centrioles [PDF]
eLife, 2018 Centrioles are cylindrical assemblies comprised of 9 singlet, doublet, or triplet microtubules, essential for the formation of motile and sensory cilia.

Current Opinion in Cell Biology, 2013 Centrioles are the key foundation of centrosomes and cilia, yet a molecular understanding of how they form has only recently begun to emerge. Building a fully functional centriole that can form a centrosome and cilium requires two cell cycles. Centriole building starts with procentriole nucleation, a process that is coordinated by the conserved ...

Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 Centrioles are among the largest protein-based structures found in most cell types, measuring approximately 250 nm in diameter and approximately 500 nm long in vertebrate cells. Here, we briefly review ultrastructural observations about centrioles and associated structures.

Molecular and Cellular Endocrinology, 2020 Centrioles are eukaryotic subcellular structures that produce and regulate massive cytoskeleton superstructures. They form centrosomes and cilia, regulate new centriole formation, anchor cilia to the cell, and regulate cilia function. These basic centriolar functions are executed in sperm cells during their amplification from spermatogonial stem cells ...

Revisiting the Role of the Mother Centriole in Centriole Biogenesis [PDF]
Science, 2007 Centrioles duplicate once in each cell division cycle through so-called templated or canonical duplication. SAK, also called PLK4 (SAK/PLK4), a kinase implicated in tumor development, is an upstream regulator of canonical biogenesis necessary for centriole formation.

Current Biology, 2010 Centrioles are conserved microtubule-based organelles that lie at the core of the animal centrosome and play a crucial role in nucleating the formation of cilia and flagella in most eukaryotes. Centrioles have a complex ultrastructure with ninefold symmetry and a well-defined length.

Centrioles and Ciliary Structures during Male Gametogenesis in Hexapoda: Discovery of New Models
Cells, 2020 Centrioles are-widely conserved barrel-shaped organelles present in most organisms. They are indirectly involved in the organization of the cytoplasmic microtubules both in interphase and during the cell division by recruiting the molecules needed for ...

Atypical Centrioles During Sexual Reproduction
Frontiers in Cell and Developmental Biology, 2015 Centrioles are conserved, self-replicating, microtubule-based 9-fold symmetric subcellular organelles that are essential for proper cell division and function.
