Japan: Researchers BioPrint & Implant Esophageal Cells Without Scaffolds

Researchers from Nagasaki University have recently made further progress in bioprinting—and without the use of scaffolds. As they become closer to their goal of 3D printing the human esophagus, the authors detail their current findings in Regeneration of esophagus using a scaffold-free biomimetic structure created with bio-three-dimensional printing . Pointing out that they are not the first research team to attempt engineering tissue to repair defects of the esophagus, a vital tube that connects the throat to the stomach, the authors explain that their new method works because they have focused on diminishing previous issues with biological incompatibility, and challenges leading to problems like esophageal stricture. The researchers, aware of the four cell types in the esophagus (squamous epithelial cells, fibroblasts, and smooth muscle cells), realized they had to create a structure that would not interfere with normal biological activity. Study overview. Cells: fibroblasts,mesenchymal stem cells, smooth muscle cells, […]
