Direct Control of Stem Cell Behavior Using Biomaterials and Genetic Factors

Figure 2

PEG chain length-dependent interactions with the PCL matrix enable stemness maintenance. Proper control of surface repellency by copolymerizing PEG_2k with PCL in a culture substrate form can improve stemness as cell-cell interaction increases relatively to cell-matrix interaction, thereby forming pseudo cell spheroids.
