Sall4 in Embryonic Development

Dec 18, 2008

Researchers at the Nevada Cancer Institute in Las Vegas found that Sall4, a zinc-finger transcription factor that is expressed very early in embryonic development with Oct4 and Nanog, plays a diverse role in regulating stem cell pluripotency during early embryonic development. Using chIP-chip analysis to map genome-wide gene targets of Sall4 in mouse ES cells, they found that the protein bound 3,223 genes, many of which have major functions in developmental and regulatory pathways. They published their results yesterday in PNAS.
