Sperm Centrioles and Their Dual Role in Flagellogenesis and Cell Cycle of the Zygote Structure, Function, and Pathology
This chapter examines the current knowledge on the role of the spermatid centrosome. The dual role of the centrosome as a spermatid basal body that generates the sperm flagellum and as the nucleation site for sperm aster formation in the zygote is mirrored in different sperm pathologies in infertile men that are reviewed in detail. Information is discussed on different sperm centriolar and cent...
متن کاملAtypical centrioles during sexual reproduction
Centrioles are conserved, self-replicating, microtubule-based, 9-fold symmetric subcellular organelles that are essential for proper cell division and function. Most cells have two centrioles and maintaining this number of centrioles is important for animal development and physiology. However, how animals gain their first two centrioles during reproduction is only partially understood. It is we...
متن کاملOccurrence of Centrioles during Skeletal and Cardiac Myogenesis
Skeletal muscle development of vertebrates is characterized by the formation of multinuclear muscle fibers through the fusion of uninucleate myoblasts (Holtzer et al ., 1958; Capers, 1960 ; Konigsberg et al ., 1960 ; Zhinkin and Andreeva, 1963 ; Mintz and Baker, 1967) . The myogenic cells constitute a line of mitotically dividing elements which serve as the basis for the initiation of skeletal ...
متن کاملBuilding centrioles
he protozoan parasite Toxoplasma gondii heads out of its host cell when Ca 2 ϩ levels peak in its cytoplasm. Now, Arrizabalaga et al. (page 653) find that proper regulation of these Ca 2 ϩ levels, and thus of Toxoplasma exit, requires a Na ϩ /H ϩ exchanger (NHE), suggesting a link between proton and Ca 2 ϩ regulation. The increase in Ca 2 ϩ levels, which can be induced artificially with an iono...
متن کاملGiant centrioles in neuropteran meiosis.
Centrioles were studied in living and fixed testes of neuropteran insects by light, phasecontrast, and electron microscopy. Giant centrioles, measuring up to 8-o fi in length (according to the species), develop in meiotic prophase, whereas only minute centrioles are found in spermatogonia. The giant centrioles have essentially the same ultrastructure as described for smaller centrioles, but the...
