Concentrated Polymer Brush-Modified Cellulose Nanofibers Promote Chondrogenic Differentiation of Human Mesenchymal Stem Cells by Controlling Self-Assembly

In order to develop new 3D cell culture systems for articular cartilage regeneration, concentrated poly(styrene sulfonate sodium salt) brush-modified cellulose nanofibers were employed as building blocks for the self-assembly of human MSCs.
