Abstract excerpt
The transformation-related protein 53 (TRP53) has a canonical role as the "guardian of the genome," serving to protect against the propagation of cells with genomic damage. Autocrine trophic signals act to block the accumulation of TRP53 in the normal preimplantation embryo. Culture of the early embryo at limiting dilutions in simple defined media limits autocrine signaling, resulting in the accumulation of...
