The Interplay of Curvature, Geometry, and Topology Shapes Tissue Organisation in Epithelial Shells
Advanced Science, EarlyView.Purely geometric 3D Voronoi models predict the organisation of epithelial shells. The interplay of curvature, geometry, and topology enriches the number of pentagons in shells with lower number of cells. Small MDCK cysts and Mouse embryos match the top polygonal configurations in a compactness‐based ranking derived from the Voronoi model. In conclusion,

Advanced Science, EarlyView.Compared to E8, mTeSR1 culture downregulated WNT and TGF‑β signaling, and upregulated neural differentiation pathways, enhancing neural priming. Under skin organoid induction conditions, mTeSR1‑cultured hESCs generated organoids with significantly higher neuroepithelial differentiation.

Estrogen-dependent uterine secretion of osteopontin activates blastocyst adhesion competence. [PDF]
, 2012 Embryo implantation is a highly orchestrated process that involves blastocyst-uterine interactions. This process is confined to a defined interval during gestation referred to as the "window of embryo implantation receptivity".

Advanced Science, EarlyView.Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Evaluating the Development and the Expression of Bax, Bcl-2, and ErbB4 Genes following Vitrification of Eight Cell and Blastocyst Embryos [PDF]
Journal of Advanced Biomedical Sciences, 2014 Background & Objective: Vitrification is an effective mean for preserving embryos. During this process, expression of implanting and apoptotic genes changes and can affect the quality of embryos.

SAV1 in Cooperation With FKBP52 Participates in Implantation
Advanced Science, EarlyView.The MST‐SAV1 complex modulates FKBP52 phosphorylation to fine‐tune PR activity, ensuring timely uterine transition to receptivity under estrogen signaling for implantation. Stromal SAV1 scaffolds MST1/2‐mediated FKBP52 phosphorylation via noncanonical Hippo to promote PR activity.
