スクリーニング応用のためのヒトiPS細胞由来神経細胞-アストロサイト共培養の3次元バイオプリンティング

Overview

This study presents a protocol for the efficient production of 3D-bioprinted cocultures of iPSC-derived neurons and astrocytes within hydrogel scaffolds. The developed model operates in 96- or 384-well formats and demonstrates high post-print viability and neurite outgrowth within seven days, while expressing maturity markers for both cell types. This approach aims to enhance the throughput and automation of 3D cell culture systems.
