Mammalian germ cell migration during development, growth, and homeostasis

Reproductive Medicine and Biology, 2019
Background Germ cells represent one of the typical cell types that moves over a long period of time and large distance within the animal body. To continue its life cycle, germ cells must migrate to spatially distinct locations for proper development ...

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

Evolution &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 ...

Comparison of the MicroRNA Expression Profiles of Male and Female Avian Primordial Germ Cell Lines

Stem Cells International, 2018
Primordial germ cells (PGCs) are the precursors of adult germ cells, and among the embryonic stem-like cells in the bird embryo, only they can transmit the genetic information to the next generation. Despite the wide range of applications, very little is

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

Reviews 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,

Study on the Effects and Mechanisms of Sea Buckthorn Fruit Pulp in Improving Polycystic Ovary Syndrome

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Sea buckthorn pulp improves metabolic and reproductive dysfunction in a letrozole‐induced PCOS mouse model and is associated with modulation of the PI3K/AKT/mTOR signaling pathway. ABSTRACT Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder characterized by ovarian dysfunction, hyperandrogenism, and insulin resistance.

Spontaneous miscarriage after intracytoplasmic sperm injection with frozen sperm of patients with testicular germ cell tumour

BJU International, Volume 138, Issue 2, Page 315-323, August 2026.
Objective To clarify the impact of chromosomal aberrations on the offspring of patients with testicular germ cell tumour (TGCT) by evaluating the outcomes of intracytoplasmic sperm injection (ICSI). Patients and Methods Under the ethical review of Yokohama City University, 12 patients with TGCT and 25 with non‐TGCT cancer who had cryopreserved sperm ...

JAK-STAT-dependent contact between follicle cells and the oocyte controls Drosophila anterior-posterior polarity and germline development

Nature Communications
The number of embryonic primordial germ cells in Drosophila is determined by the quantity of germ plasm, whose assembly starts in the posterior region of the oocyte during oogenesis.

Establishment of Human Formative Pluripotent Stem Cell‐Like Cells Exhibiting Amniotic Differentiation Potentials

Cell Proliferation, Volume 59, Issue 8, August 2026.
The hfPSC‐LCs could be established from naïve hESCs, conventional hESCs, hiPSCs, and human blastocysts. The hfPSC‐LCs hold robust capacity for three germ layers, hPGCLCs, and hALPCs. ABSTRACT Human embryos undergo pivotal morphogenetic remodelling shortly after implantation. The understanding of this crucial stage is severely impeded by the scarcity of

AID‐Mediated Protein Knockdown Reveals the Requirement of NANOS2 in Prenatal Gonocytes for Establishing Functional Spermatogonial Stem Cells

Development, Growth &Differentiation, Volume 68, Issue 6, August 2026.
ABSTRACT The RNA‐binding protein NANOS2 plays a crucial role in male gonocyte development and the maintenance of spermatogonial stem cells. In the absence of the Nanos2 gene (Nanos2‐KO), germ cells fail to enter G0 arrest and initiate the male differentiation program (including DNA methylation and the piRNA pathway), ultimately undergoing apoptosis ...
