Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...

Establishing Germline Chimeric Chickens Using Primordial Germ Cells

open access: yesThe Journal of Poultry Science, 2012
Chicken primordial germ cells (PGCs) are used to restore and conserve genetic resources of some endangered birds or flocks of domestic chickens. When PGCs are transferred from a donor to a recipient, they can survive and gain sexual maturity in the ...

DAZL Limits Pluripotency, Differentiation, and Apoptosis in Developing Primordial Germ Cells

open access: yesStem Cell Reports, 2014
Summary The scarcity of primordial germ cells (PGCs) in the developing mammalian embryo hampers robust biochemical analysis of the processes that underlie early germ cell formation. Here, we demonstrate that DAZL, a germ cell-specific RNA binding protein,

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Primordial germ-cell development: the zebrafish perspective

open access: yesNature Reviews Genetics, 2003
Primordial germ cells follow a characteristic developmental path that is manifested in the specialized regulation of basic cell functions and behaviour. Recent studies in zebrafish have greatly enhanced our understanding of the mode of specification of primordial germ cells, cell-fate maintenance and the migration of these cells towards their target ...

Cytologic Characteristics of the Feline Ovary at Different Sexual Stages

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT Background Cytology is a valuable diagnostic tool in veterinary medicine, allowing rapid and minimally invasive diagnosis. However, its application in the reproductive tracts of small animals is limited, primarily used to assess mammary masses and stage the estrous cycle.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Terminal Filament Bundling Underlies the Development of Ovariole Number Dimorphism Between Queen and Worker Ants

open access: yesEvolution &Development, Volume 28, Issue 3, September 2026.
We trace the formation of the cell structures known to determine ovariole number in the model insect Drosophila melanogaster, called terminal filaments. By investigating the formation of terminal filaments and ovarioles during queen and worker development in ants, we confirm the existence of terminal filament bundling (white arrows) and show that it ...

Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,
