Attempts to exhaustively tabulate the interactions within developmental signaling networks that coordinate these hierarchical cell fate transitions are difficult to interpret or fit to data. An alternative approach models the cellular decision-making process as a flow in an abstract landscape whose signal-dependent topography defines the possible developmental outcomes and the transitions between them. Prior applications of this formalism have built landscapes in low-dimensional spaces without explicit maps to gene expression. Here, we present a computational geometry framework for fitting dynamical landscapes directly to high-dimensional single-cell data. Our method models the time evolution of probability distributions in gene expression space, enabling landscape construction with minimal free parameters and precise characterization of dynamical features, including fixed points, unstable manifolds, and basins of attraction. We demonstrate the applicability of this framework to multicolor flow-cytometry and RNA-seq data. Applied to a stem cell system that models ventral neural tube patterning, we recover a family of morphogen-dependent landscapes whose valleys align with canonical neural progenitor types. Remarkably, simple linear interpolation between landscapes captures signaling dependence, and chaining landscapes together reveals irreversible behavior following transient morphogen exposure. Our method combines the interpretability of landscape models with a direct connection to data, providing a general framework for understanding and controlling developmental dynamics.<\/jats:p>","DOI":"10.1073\/pnas.2521762122","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T18:48:02Z","timestamp":1764787682000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":16,"title":["Reconstructing Waddington\u2019s landscape from data"],"prefix":"10.1073","volume":"122","author":[{"given":"Dillon J.","family":"Cislo","sequence":"first","affiliation":[{"name":"Center for Studies in Physics and Biology","place":["New York"]},{"name":"Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
