Condensed Mitochondria Assemble Into the Acrosomal Matrix During Spermiogenesis

Frontiers in Cell and Developmental Biology, 2022
Mammalian spermatogenesis is associated with the transient appearance of condensed mitochondria, a singularity of germ cells with unknown function.

Quantification of cristae architecture reveals time-dependent characteristics of individual mitochondria

Life Science Alliance, 2020
A novel, machine-learning approach to quantify cristae density and architecture in live-cell super-resolution imaging characterizes the ultrastructural parameters of individual mitochondria over time.

An interactive deep learning-based approach reveals mitochondrial cristae topologies

PLoS Biology, 2023
The convolution of membranes called cristae is a critical structural and functional feature of mitochondria. Crista structure is highly diverse between different cell types, reflecting their role in metabolic adaptation.

The Maintenance of Mitochondrial DNA Integrity and Dynamics by Mitochondrial Membranes

Life, 2020
Mitochondria are complex organelles that harbour their own genome. Mitochondrial DNA (mtDNA) exists in the form of a circular double-stranded DNA molecule that must be replicated, segregated and distributed around the mitochondrial network.

A novel homozygous variant in MICOS13/QIL1 causes hepato‐encephalopathy with mitochondrial DNA depletion syndrome

Molecular Genetics & Genomic Medicine, 2020
Background Mitochondrial DNA depletion syndrome (MTDPS) is part of a group of mitochondrial diseases characterized by a reduction in mitochondrial DNA copy number.

Using Expansion Microscopy to Visualize and Characterize the Morphology of Mitochondrial Cristae

Frontiers in Cell and Developmental Biology, 2020
Mitochondria are double membrane bound organelles indispensable for biological processes such as apoptosis, cell signaling, and the production of many important metabolites, which includes ATP that is generated during the process known as oxidative ...

MICOS coordinates with respiratory complexes and lipids to establish mitochondrial inner membrane architecture

eLife, 2015
The conserved MICOS complex functions as a primary determinant of mitochondrial inner membrane structure. We address the organization and functional roles of MICOS and identify two independent MICOS subcomplexes: Mic27/Mic10/Mic12, whose assembly is ...

Development of the crista ampullaris in the mouse

The Journal of Laryngology & Otology, 1986
SummaryThe process of development of the crista ampullaris has been investigated in the mouse using SEM.Cristae ampullaris of the CBA/CBA mice, from the 13.5th gestational day to the day 2 weeks by were studied.On the 13.5th gestational day, there were numerous microvilli and a primary cilium on the crista ampullaris.

Hyalosira (Diatomeae: Grammatophoraceae) from Florida Keys, U.S.A., Including Two New Species with Consistent Ornamentation

Diversity
Diatoms are the most numerous of algae and scanning electron microscopy continues to reveal ever-increasing diversity. Two new species of Hyalosira from Florida add new characters distinguishing species in this recently redefined genus: H. ornata sp. nov.
