Abstract
A Transcriptional Ridge in the Waddington Landscape. The Waddington landscape model, proposed in 1957, provides a powerful framework for understanding cell fate determination (Waddington, 1957). As development progresses, cells become restricted to distinct fates, separated by high "ridges" that prevent identity switching. A recent study in Nature Genetics uncovers such a ridge in hepatocyte lineage specification (Lim et al., 2025). Lim et al. report that prospero homeobox protein 1 (PROX1) acts as a hepatocyte-specific safeguard repressor, ensuring lineage stability by actively suppressing alternative cell fates and preventing cholangiocarcinoma development.
期刊介绍:
Cellular Reprogramming is the premier journal dedicated to providing new insights on the etiology, development, and potential treatment of various diseases through reprogramming cellular mechanisms. The Journal delivers information on cutting-edge techniques and the latest high-quality research and discoveries that are transforming biomedical research.
Cellular Reprogramming coverage includes:
Somatic cell nuclear transfer and reprogramming in early embryos
Embryonic stem cells
Nuclear transfer stem cells (stem cells derived from nuclear transfer embryos)
Generation of induced pluripotent stem (iPS) cells and/or potential for cell-based therapies
Epigenetics
Adult stem cells and pluripotency.
