Peptides-modified polystyrene-based polymers as high-performance substrates for the growth and propagation of human embryonic stem cells
文献摘要：
As human stem cells with the special pluripotency play important roles in the innovative drug discovery and regenerative medicine,development of extracellular matrix(ECM)mimetics or functional materi-als that can support stem cell growth and propagation is of high significance.Despite numerous efforts spent,one major limitation restricting the wide applications of stem cells to the clinical translation is the lack of efficient strategies for low cost and large-scale stem cell production under xeno-free culture con-ditions.Herein,we reported a new strategy with peptides-modified polystyrene-based polymers coated onto the surface of coverslips for the growth and reproduction of human embryonic stem cells(hESCs).The modified peptides are the active parts of proteins which has been shown to contribute to the pluripo-tent stem cell attachment or proliferation.The peptides were linked to the glass coverslips coated by the polymer materials via chemical crosslinking,and the composite substrates successfully maintain the long-term growth of HUES-7,H7 and DF699.Our study shows that the coating of polystyrene-derived polymer modified by our developed peptides is a good matrix for long-term growth and reproduction of stem cells.This polystyrene-derived polymer substrate can be produced in large scale and stored for a long time.The most important thing is that it can support the growth of undifferentiated human pluripotent stem cells(hPSCs)for more than ten passages,which could provide a new and relatively easy way to amplify hESCs in vitro.
