Ultrastructural changes during megasporogenesis in Epipactis (Orchidaceae)
Acta Societatis Botanicorum Poloniae, 2014 Plastids were temporarily localized within the micropylar portion of the early first prophase Epipactis meiocyte. Some of these plastids were observed in close proximity to the nuclear envelope.

Homolog pairing during meiosis : dyneins on the move [PDF]
, 2010 Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

The telomere bouquet facilitates meiotic prophase progression and exit in fission yeast
Cell Discovery, 2017 During meiotic prophase, chromosome arrangement and oscillation promote the pairing of homologous chromosomes for meiotic recombination. This dramatic movement involves clustering of telomeres at the nuclear membrane to form the so-called telomere ...

Cohesin dynamics during meiotic prophase
, 2013 For faithful segregation during meiosis, chromosomes must be physically linked by both sister chromatid cohesion (SCC), provided by cohesin, and at least one crossover (CO). In mitosis, cohesin is dynamically associated with chromatin and this has been shown to be crucial for the repair of DSBs.

Somatic Pairing in Drosophila virilis Mitosis [PDF]
, 1975 In neuroblast cells homologous chromosomes tend to pair during prophase of mitosis. Heterochromatic elements of homologous chromosomes are widely separated in very early prophase, at which time the euchromatin is poorly stained.

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]
, 2020 In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Advanced Science, EarlyView.CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

CD168 Identifies Proliferating Pancreatic Islet Cells in Murine and Human
Advanced Science, EarlyView.This study identifies CD168 as a conserved surface marker for proliferating β‐cells in mouse, human islets, and pancreatic islet tumors. CD168⁺ cells show high proliferation and low insulin expression. CD168+ cells form mostly uni‐β lineage clones, and some of the clones are multi‐lineage.

Cell Reports, 2016 Mammalian NIMA-like kinase-1 (NEK1) is a dual-specificity kinase highly expressed in mouse germ cells during prophase I of meiosis. Loss of NEK1 induces retention of cohesin on chromosomes at meiotic prophase I.
