Tube morphogenesis: making and shaping biological tubes.

abstract：:Maintaining the pluripotency of mouse ES cells requires both LIF (leukemia inhibitory factor) and unknown factors in serum. The paper from Ying et al. in this issue of Cell shows that BMP (bone morphogenetic protein) can replace serum in this capacity, defining molecular requirements for ES cell self-renewal. ...
