Schematic illustration and optical photographs of 3D bioprinted a helix-shape (mesenchymal stem cell (MSC) spheroids), b initials of Penn State University (PSU, MSC spheroids), c five-layer tubular (MSC spheroids), and d double helix-shape constructs using MSC spheroids with 150 μm (F-actin) and 450 μm (Hoechst) in radius in 1.2% Carbopol yield-stress gel. The red dashed line denotes the region magnified.
