Microtechnology in Space Bioreactors
CHIMIA, 1999 Space biology is a young and rapidly developing discipline comprising basic research and biotechnology. In the next decades it will play a prominent role in the International Space Station (ISS). Therefore, there is an increasing demand for sophisticated instrumentation to satisfy the requirements of the future projects in space biology.

Tailored 3D Lattice Microstructures for Enhanced Functionality in Blood‐Gas Exchange
Advanced Science, EarlyView.Common hollow fiber structures are associated with inhomogeneous flow, leading to many complications in the medical application of extracorporeal membrane oxygenation. Using locally adapted lattice structures, the overall flow distribution can be manipulated.

IFITM2 Modulates Endocytosis Maintaining Neural Stem Cells in Developing Neocortex
Advanced Science, EarlyView.This study reveals IFITM2 as a key regulator of endocytosis in radial glial cells (RGCs) during brain development. IFITM2's YXXø motif and phosphoinositide‐binding residues (K82/K87) are essential for endosome formation. IFITM2 deficiency disrupts the embryonic cortical neurogenesis, revealing a conserved mechanism linking endocytic dynamics to neural ...

Numerical Solution of a Complete Formulation of Flow in a Perfusion Bone-Tissue Bioreactor Using Lattice Boltzmann Equation Method [PDF]
arXiv, 2011 We report the key findings from numerical solutions of a model of transport within an established perfusion bioreactor design. The model includes a complete formulation of transport with fully coupled convection-diffusion and scaffold cell attachment. It also includes the experimentally determined internal (Poly-L-Lactic Acid (PLLA)) scaffold boundary,
