Lineage labeling with zebrafish hand2 Cre and CreERT2 recombinase CRISPR knock‐ins

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The ability to generate endogenous Cre recombinase drivers using CRISPR‐Cas9 knock‐in technology allows lineage tracing, cell type‐specific gene studies, and in vivo validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish hand2 Cre and CreERT2 drivers

A simple mechanochemical model for calcium signalling in embryonic epithelial cells [PDF]

open access: yesarXiv, 2019
Calcium (Ca2+) signalling is one of the most important mechanisms of information propagation in the body. In embryogenesis the interplay between Ca2+ signalling and mechanical forces is critical to the healthy development of an embryo but poorly understood.

Developmental and genomic architecture of plant embryogenesis: from model plant to crops

open access: yesPlant Communications, 2021
Embryonic development represents an important reproductive phase of sexually reproducing plant species. The fusion of egg and sperm produces the plant zygote, a totipotent cell that, through cell division and cell identity specification in early ...

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

open access: yesDevelopmental 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 ...

Multicell-Fold: geometric learning in folding multicellular life [PDF]

open access: yesarXiv
During developmental processes such as embryogenesis, how a group of cells fold into specific structures, is a central question in biology that defines how living organisms form. Establishing tissue-level morphology critically relies on how every single cell decides to position itself relative to its neighboring cells.

Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Age‐incidence patterns of seminoma and nonseminoma among males and females in Germany and the United States, 2008–2016

open access: yesAndrology, Volume 11, Issue 1, Page 65-72, January 2023., 2023
Abstract Background & objectives The comparison of the incidence of gonadal germ cell tumors among males and females can provide insights that cannot be gained by separately studying these tumors. Material and methods Incidence data on male and female gonadal germ cell tumors were drawn from the cancer registries of North Rhine‐Westphalia, Germany, and

Slow intermixing of cells during Xenopus embryogenesis contributes to the consistency of the blastomere fate map [PDF]

open access: yes, 1989
The relatively consistent fates of the blastomeres of the frog embryo could result from (i) predetermination of the blastomeres or (ii) reproducible morphogenetic cell movements. In some species, the mixing of the cells during development provides a test
