Ex Vivo Spatiotemporal Characterization of Spermatogenesis in Mouse Testicular Organoids

Advanced Science, EarlyView.
To date, in vitro spermatogenesis remains a challenge in reproductive medicine. In this study, Sun et al. developed a promising in vitro strategy to generate testicular organoids that enable germ cells from newborn mice to enter meiosis, complete chromosome recombination and synapsis, and develop into haploid spermatids.

Integrated analysis of single-cell embryo data yields a unified transcriptome signature for the human pre-implantation epiblast

Development, 2017
Single-cell profiling techniques create opportunities to delineate cell fate progression in mammalian development. Recent studies have provided transcriptome data from human pre-implantation embryos, in total comprising nearly 2000 individual cells ...

Dissecting the dynamics of signaling events in the BMP, WNT, and NODAL cascade during self-organized fate patterning in human gastruloids. [PDF]

, 2019
During gastrulation, the pluripotent epiblast self-organizes into the 3 germ layers-endoderm, mesoderm and ectoderm, which eventually form the entire embryo.

Pre‐oviposition development of the brown anole (Anolis sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Differential sensitivity of midline development to mitosis during and after primitive streak extension

Developmental Dynamics, EarlyView.
Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).

Epiblast formation by Tead-Yap-dependent expression of pluripotency factors and competitive elimination of unspecified cells

bioRxiv, 2018
The epiblast is a pluripotent cell population first formed in preimplantation embryos and its quality is important for proper development. Here, we examined the mechanisms of epiblast formation and found that the Hippo pathway transcription factor Tead ...

A Primary Role for the Tsix lncRNA in Maintaining Random X-Chromosome Inactivation

Cell Reports, 2015
Differentiating pluripotent epiblast cells in eutherians undergo random X-inactivation, which equalizes X-linked gene expression between the sexes by silencing one of the two X-chromosomes in females. Tsix RNA is believed to orchestrate the initiation of
