Geomorphic Reach Scale Controls the Availability of Brown Trout Spawning Sites in Große Mühl, An Alpine River of the Bohemian Massif

open access: yesRiver Research and Applications, Volume 41, Issue 8, Page 1712-1725, October 2025.
ABSTRACT Studies on the quantity and quality of the spawning habitats of resident brown trout on the catchment scale of rivers are rare. The spawning habitats of salmonids are locally nested along river corridors and are found throughout variable channel patterns, with a preference for sediments composed of gravel and cobbles and appropriate flow ...

Generation of Advanced Blood–Brain Barrier Spheroids Using Human‐Induced Pluripotent Stem Cell‐Derived Brain Capillary Endothelial‐Like Cells

open access: yesAdvanced Biology, Volume 9, Issue 4, April 2025.
In this article, the establishment and characterization of a self‐assembled 3D BBB spheroid model using human induced pluripotent stem cell (hiPSC)‐derived and primary cells is reported. Spheroids demonstrate in‐vivo like tight junction ultrastructure and, in comparison to 2D mono‐cultures, higher transcript expression of BBB specific genes.
