Formation of a polarised primitive endoderm layer in embryoid bodies requires fgfr/erk signalling.
The primitive endoderm arises from the inner cell mass during mammalian pre-implantation development. It faces the blastocoel cavity and later gives rise to the extraembryonic parietal and visceral endoderm.

This research provides a complete morphoanatomical description of Lysimachia nummularia, as well as a HPTLC profile. Standard techniques of light and scanning electron microscopies, as well as standard techniques of HPTLC, were used. ABSTRACT Primulaceae are distributed all over the world, encompassing around 2590 species.

ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Embryonic stem (ES) cell technology holds promise for curing innumerable human ailments. However, studies of the endoderm germ layer and its derivatives (liver, pancreas, and lung) are lacking.

ABSTRACT Long‐term exposure to low‐dose food contact materials (FCMs) has raised concerns regarding developmental toxicity. In the present study, we prioritized FCMs with potential developmental toxicity using a weight‐of‐evidence computational model, which predicted 127 chemicals to be of high concern.

Tukushi modulates Xnr2, FGF, and and BMP signalling: Regulation of Xenopus Germ Layer Formation
BACKGROUND: Cell-cell communication is essential in tissue patterning. In early amphibian development, mesoderm is formed in the blastula-stage embryo through inductive interactions in which vegetal cells act on overlying equatorial cells. Members of the

Vertebrate development: Multiple phases to endoderm formation
Recent results support a two-step model for endoderm formation in amphibian embryos, in which endoderm is initially specified by localised maternal factors, including the transcription factor VegT, but is then maintained by extracellular signalling ...

During the trunk to tail transition the mammalian embryo builds the outlets for the intestinal and urogenital tracts, lays down the primordia for the hindlimb and external genitalia, and switches from the epiblast/primitive streak (PS) to the tail bud as

Patients in intensive care units often experience lung injuries, complicated by brain problems. Advanced laboratory tools, organoids, and organs‐on‐chips facilitated the study of multiorgan interactions, help us understand the communication between the lungs and brain.

Concerted cell divisions in embryonic visceral endoderm guide anterior visceral endoderm migration.
Migration of Anterior Visceral Endoderm (AVE) is a critical symmetry breaking event in the early post-implantation embryo development and is essential for establishing the correct body plan.
