A Spotlight on Yolk‐sac Tumors: Molecular Pathology, Current Diagnostics, and Novel Therapeutics

Andrology, EarlyView.
ABSTRACT Background Yolk‐sac tumors are an aggressive subtype of testicular cancer that significantly contribute to disease progression and therapy resistance, especially in adults. While testicular cancer generally has high cure rates with cisplatin‐based treatment, adult yolk‐sac tumors often appear as components of mixed tumors with poor response to

Derivation of Mouse Dome‐Shaped Trophoblast Stem Cells With Low Heterogeneity From Blastocysts

Cell Proliferation, EarlyView.
Here, Liu et al. report the generation of mouse dome‐shaped trophoblast stem cells (dTSCs) with low heterogeneity and autonomous differentiation potential. dTSCs robustly generate all trophoblast lineages in vitro and contribute to the placenta in vivo, providing a refined model for studying trophoblast development and related disorders.

Spatiotemporal segmentation of contraction waves in the extra-embryonic membranes of the red flour beetle

BMC Bioinformatics
Background In this paper, we introduce an image analysis approach for spatiotemporal segmentation, quantification, and visualization of movement or contraction patterns in 2D+t and 3D+t microscopy recordings of biological tissues. The development of this

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).

Extraembryonic Membranes and Placentation in the Mexican Snake Conopsis lineata

Journal of Morphology
ABSTRACT Extraembryonic membranes provide protection, oxygen, water, and nutrients to developing embryos, and their study generates information on the origin of the terrestrial egg and the evolution of viviparity. In this research, the morphology of the extraembryonic membranes and the types of placentation in the

Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

Advanced Science, Volume 13, Issue 49, 3 September 2026.
ABSTRACT Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs. By optimizing bioink composition, printing was accomplished in a single‐step approach. Within one week, hiMPCs differentiated into both CD31+

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, Volume 255, Issue 9, Page 867-880, September 2026.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

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.

Transport mechanism and modeling of microporous carbon membranes

, 2019
\u3cp\u3eCarbon molecular sieve membranes (CMSM) have gained increased interest in the last decade as they allow an excellent compromise between performance, in terms of permeability and separation factors, while exhibiting a very good chemical and ...
