Research progress in feeder layers of human embryonic stem cells / 国际生物医学工程杂志

ABSTRACT

Human embryonic stem cell (hES cells) lines can be derived from the inner cell mass (ICM) of preimplantation blastocysts.hES cells are commonly defined as undifferentiated pluripotent cells that can proliferate and have the capacity of both self-renewal and differentiation into one or more types of specialized cells.hES cells remain undifferentiated when culture on feeder layers,such as murine embryonic fibroblasts (MEFs).It is believed that various factors secreted from feeder layers are necessary to prevent hES cell from differentiation.In this review,we will summarize the advantages and disadvantages of various types of feeder cells by which a reference for future research will be provided.
