Patterns of Autonomous and Conditional Neural Specification for the Brain and Ventral Nerve Cord in Annelida

open access: yesEvolution &Development, Volume 28, Issue 3, September 2026.
Diagrams of blastomere isolations in Capitella teleta and Platynereis dumerilii showing autonomous head neural tissue (from 1q) and trunk neural tissue (from 2d) as well as a decoupling of D–V axis formation from trunk neural tissue in annelids. ABSTRACT Evolution of central nervous systems is a long‐debated topic.

Two Paralogues as They Like It: Conserved and Divergent Evolution of Vertebrate Gcm Genes

open access: yesEvolution &Development, Volume 28, Issue 3, September 2026.
Comparative overview of Gcm1 and Gcm2 paralogues across vertebrates. Gcm2 is conserved in pharyngeal‐derived organs across gnathostomes, whereas Gcm1 shows lineage‐specific diversification from an ancestral pharyngeal context, including secondary loss in teleosts, distinct expression in bichir gills and skin, and broader expression in mammals ...

Patient‐Derived iPSC‐MSC Modelling Reveals Reversible GSK3‐Mediated Suppression of Mesenchymal Lineage Differentiation in Legg‐Calvé‐Perthes Disease

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 17, September 2026.
ABSTRACT Legg‐Calvé‐Perthes disease (LCPD) is an idiopathic paediatric osteonecrosis characterized by avascular injury to the femoral head, resulting in structural collapse and early osteoarthritis. Although mesenchymal stem cell (MSC) dysfunction has been implicated, the underlying mechanisms remain unclear due to the absence of human disease models ...

Dissection of the Mixl1 gene regulation network in endoderm development

open access: yes, 2023
Gastrulation, a key process in early embryonic development, involves the formation of the three germ layers that will eventually become all tissues of the adult mouse. The Mix paired-like homeobox (Mixl1) transcription factor, expressed in both mouse and

Spatiotemporal remodelling of the cloacal region determines the position of the anal opening in mouse embryos

open access: yesJournal of Anatomy, Volume 249, Issue 3, Page 652-658, September 2026.
In E13.25 mouse embryo, the urorectal septum consistently positioned on the dorsodistal side of the cloacal membrane. Through 3D reconstruction of the cloacal internal space, we revealed that the position of the anal opening is established prior to cloacal membrane rupture and is located at the junction between the hindgut lumen (blue) and an expanded ...

Pregnancy Outcomes Following Artificial Insemination and Embryo Transfer in Dairy Cows—Expectations vs. Reality

open access: yesReproduction in Domestic Animals, Volume 61, Issue S2, September 2026.
ABSTRACT Bovine embryo transfer (ET) has been a consistently growing market worldwide with in vitro produced (IVP) embryos now far outnumbering those produced by traditional superovulation. Because transfer of a viable blastocyst‐stage embryo to the uterus bypasses many of the potential biological causes of early pregnancy failure associated with ...

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

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
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 ...

Formation of endoderm on EBs, EPLEBs, EBMs.

open access: yes, 2013
A–F. Scanning electron micrographs of EBs (A, D), EBMs (B, E) and EPLEBs (C, F) on days 2.5 (A–C) and 5 (D–F). Arrowheads mark the boundary of the prospective patch of primitive endoderm on EBs on day 2.5 (A) and the prospective endoderm population ...

Evolution of the mechanisms and molecular control of endoderm formation

open access: yes
Endoderm differentiation and movements are of fundamental importance not only for subsequent morphogenesis of the digestive tract but also to enable normal patterning and differentiation of mesoderm- and ectoderm-derived organs.
