Conceptus signals for establishment and maintenance of pregnancy
Reproductive Biology and Endocrinology, 2004 Establishment and maintenance of pregnancy results from signaling by the conceptus (embryo/fetus and associated extraembryonic membranes) and requires progesterone produced by the corpus luteum (CL).

Imaging and genetic toolbox to study Arabidopsis embryogenesis
New Phytologist, Volume 250, Issue 3, Page 1483-1491, May 2026.Summary Embryogenesis in the model plant Arabidopsis thaliana provides a framework for understanding how cell polarity and patterning coordinate with hormonal signalling to establish the plant body plan. Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines ...

Polydactylous limbs in Strong's Luxoid mice result from ectopic polarizing activity [PDF]
, 1995 Strong's Luxoid (1st^D) is a semidominant mouse mutation in which heterozygotes show preaxial hindlimb polydactyly, and homozygotes show fore- and hindlimb polydactyly.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, Volume 38, Issue 20, 7 April 2026.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Birth Defects Research, Volume 118, Issue 4, April 2026.ABSTRACT Background Animal models remain essential for understanding developmental toxicology, providing insights into how in utero exposures affect fetal and placental outcomes. Litter‐bearing species are widely used due to their efficiency and reproducibility, but conventional approaches often summarize outcomes at the litter level, masking ...

Expression of calcium transporting proteins by the extraembryonic membranes of squamate reptiles
The FASEB Journal, 2007 Eighty percent of squamate reptiles (snakes and lizards) lay eggs; however, over 100 species bear live young. The evolutionary transition from oviparity to viviparity involves loss of the eggshell, an important source of calcium for developing embryos.

Prominent Expression of Xenobiotic Efflux Transporters in Mouse Extraembryonic Fetal Membranes Compared with Placenta [PDF]
Drug Metabolism and Disposition, 2008 Fetal exposure to xenobiotics can be restricted by transporters at the interface between maternal and fetal circulation. Previous work identified transporters in the placenta; however, less is known about the presence of these transporters in the fetal membranes (i.e., yolk sac and amniotic membranes). The purpose of this study was to quantify mRNA and

The Roles of Macrophage Lineage Cells (MLCs) in Brain Aging
CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.This review highlights the critical role of macrophage lineage cells (MLCs), including microglia, border‐associated macrophages (BAMs), and CNS‐infiltrating monocyte‐derived macrophages (MDMs), in brain aging. It explores the drivers and propagation of MLCs senescence and discusses potential therapeutic strategies targeting MLCs senescence.
