Dynamics of centromere pairing in mouse spermatocytes.
, 2012 (A) Dynamics of centromere pairing observed in squashed spermatocytes of wild-type mice at meiotic prophase I. In wild-type spermatocytes the number of CREST foci remained constant as cells progressed from pachytene to diplotene (22.9±0.7 and 22.7±0.9 ...

Defects in Meiotic Recombination Delay Progression Through Pachytene in Tex19.1-/- Mouse Spermatocytes [PDF]
, 2018 Recombination, synapsis, chromosome segregation and gene expression are co-ordinately regulated during meiosis to ensure successful execution of this specialised cell division.

The physiology of the reproductive cycle of the powan of Loch Lomond, Coregonus lavaretus (L) (Euteleostei, Salmonidae) in relation to the deposition and mobilization of storage products [PDF]
, 2012 There have been numerous studies in which the reproductive cycles of teleosts have been correlated with either environmental cycles or associated physiological cycles, or both. Such correlation is seldom accurately achieved; usually because

Advanced Science, EarlyView.DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.

p53 and TAp63 participate in the recombination-dependent pachytene arrest in mouse spermatocytes. [PDF]
PLoS Genetics, 2017 To protect germ cells from genomic instability, surveillance mechanisms ensure meiosis occurs properly. In mammals, spermatocytes that display recombination defects experience a so-called recombination-dependent arrest at the pachytene stage, which ...

MTs dynamics in spermatocytes.
, 2014 A, Pachytene spermatocytes stained for SCP3 (red), α-Tubulin (green) and DAPI (blue). Cells were prepared without hypotonic treatment and then fixed without Triton-X100 (-). Or, cells were prepared with mild (mild extraction) or severe (severe extraction)

Differing requirements for Augmin in male meiotic and mitotic spindle formation in Drosophila [PDF]
Open Biology, 2014 Animal cells divide using a microtubule-based, bipolar spindle. Both somatic, mitotic cells and sperm-producing male meiotic spermatocytes use centrosome-dependent and acentrosomal spindle-forming mechanisms.

The Anatomical Record, EarlyView.Abstract Stenopodidea represents one of the basal lineages within Pleocyemata, yet the male reproductive system (MRS) of this group remains poorly understood, with limited information available regarding its morphology and function. This study provides the first detailed description of the MRS in four stenopodidean shrimp species from two families ...

Defective DSB repair in UBR2−/− spermatocytes.
, 2012 (A) Prolonged retention of the γH2AX staining in pachytene chromosomes of UBR2−/− spermatocytes. Wild type and UBR2−/− spermatocytes were stained with γH2AX (green) and SCP3 (red). Scale bars: 10 µm.

Robertsonian chromosomes and the nuclear architecture of mouse meiotic prophase spermatocytes
Biological Research, 2014 BACKGROUND: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains from different bivalents.
