3D Bioprinted Coaxial Testis Model Using Human Induced Pluripotent Stem Cells:A Step Toward Bicompartmental Cytoarchitecture and Functionalization

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
The ability of human induced pluripotent stem cells (hiPSCs) to model developmental processes makes them a promising source for engineering testicular tissues to study in vitro maturation and sperm production. This work describes the first hiPSC‐derived testicular model and shows that it captures functional aspects of prepubertal testicular tissues ...

Engineered In Vitro Multi‐Cell Type Ventricle Model Generates Long‐Term Pulsatile Flow and Modulates Cardiac Output in Response to Cardioactive Drugs

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
This study presents an innovative in vitro model of a human left ventricle using biofunctionalized PDMS membranes and human iPSC‐derived cardiomyocytes. The engineered ventricle demonstrates stable, long‐term pulsatile flow, and physiological responses to cardioactive drugs.

Dynamic Asset Allocation with Asset-Specific Regime Forecasts [PDF]

arXiv
This article introduces a novel hybrid regime identification-forecasting framework designed to enhance multi-asset portfolio construction by integrating asset-specific regime forecasts. Unlike traditional approaches that focus on broad economic regimes affecting the entire asset universe, our framework leverages both unsupervised and supervised ...
