Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

Advanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

De Novo Gene Transcription of Connexin Mediates Cytoplasmic Fluid Exchange and Flocking Transitions in Physiological and Cancerous Epithelial Systems

Advanced Science, EarlyView.
EGF‐induced de novo transcription of connexins Cx26 and Cx31 promotes flocking behavior that fluidizes epithelia and enables coordinated collective migration. Connexin‐driven cytoplasmic exchange mechanistically links growth‐factor signaling to invasive dynamics.

Endometrial Assembloid Model Reveals Endometrial Gland Development Regulation by Estradiol‐Driven WNT7B Suppression

Advanced Science, EarlyView.
This study developed a 3D endometrial assembloid model to study how uterine glands form and develop. They discovered key interactions between different cell types and identified WNT7B as a regulator controlled by estradiol‐mediated TGFβ1‐VDR interaction.
