Meiotic wave adds extra asymmetry to the development of female chicken gonads [PDF]

open access: yes, 2015
Development of female gonads in the chicken is asymmetric. This asymmetry affects gene expression, morphology, and germ cell development; consequently only the left ovary develops into a functional organ, whereas the right ovary remains vestigial.

Identification of side population cells in mouse primordial germ cells and prenatal testis [PDF]

open access: yes, 2011
In mammals, the stem cells of spermatogenesis are derived from an embryonic cell population called primordial germ cells (PGCs). Spermatogonial stem cells displaying the "side population" (SP) phenotype have been identified in the immature and adult ...

Implementation of meiosis prophase I programme requires a conserved retinoid-independent stabilizer of meiotic transcripts

open access: yesNature Communications, 2016
Meiosis is a cell division program that produces haploid gametes and is initiated by a retinoic acid-dependent process. Here the authors report that a meiosis-specific protein, MEIOC, is upregulated in a retinoic acid-independent manner and is required ...
