Nanog is cloned by Smith A and Yamanaka S' groups almost at the same time in 2003 (two cell papers). Smith A's group also studied Oct4 () and BMP(). The question is about a recent cell paper by Smith A's group in Cell. According the that paper: "Nanog can command constitutive self-renewal of ES cells (Chambers et al., 2003) and appears able to reverse precommitment; E# R# y8 ?* y7 i2 k1 k" c" l
perturbations of the pluripotent state. Nanog also greatly increases the efficiency of nuclear reprogramming by

that Nanog is in fact decisive for attaining this pluripotent ground state. However, this requirement is during the final phase of reprogramming when other key factors are already present and may be fulfilled by activation of endogenous Nanog. A role in7 T; z3 d& w/ S

Hope those papers are helpful to understand the background information for discussion.
