Abstract

Current neural induction protocols for human embryonic stem (hES) cells rely on embryoid body formation, stromal feeder co-culture or selective survival conditions. Each strategy has considerable drawbacks, such as poorly defined culture conditions, protracted differentiation and low yield. Here we report that the synergistic action of two inhibitors of SMAD signaling, Noggin and SB431542, is sufficient to induce rapid and complete neural conversion of >80% of hES cells under adherent culture conditions. Temporal fate analysis reveals the appearance of a transient FGF5(+) epiblast-like stage followed by PAX6(+) neural cells competent to form rosettes. Initial cell density determines the ratio of central nervous system and neural crest progeny. Directed differentiation of human induced pluripotent stem (hiPS) cells into midbrain dopamine and spinal motoneurons confirms the robustness and general applicability of the induction protocol. Noggin/SB431542-based neural induction should facilitate the use of hES and hiPS cells in regenerative medicine and disease modeling and obviate the need for protocols based on stromal feeders or embryoid bodies.

  • Noggin is essential for neural lineage induction via bone morphogenic protein (BMP) antagonism.

    “Noggin is essential for neural lineage induction via bone morphogenic protein (BMP) antagonism (Chambers et al., 2009).”

    From Challenges and solutions in transitioning to animal-free standards: a comprehensive analysis of components in human cell-based developmental neurotoxicity assays (2026) · cites this paper as Chambers et al., 2009

    The supplied passages labeled Abstract say Noggin represses endogenous BMP signals and, with SB431542, promotes efficient neural conversion of human pluripotent cells. They do not establish that Noggin is essential for neural lineage induction generally; the paper says Noggin alone is insufficient under its defined culture conditions. (LLM, conf=0.88)

  • Neural induction in brain organoids commonly includes SMAD signalling inhibition followed by specific morphogens and fate-specifying molecules.

    “Commonly, neural induction in brain organoids includes inhibition of SMAD signalling to inhibit mesoderm and endoderm formation, followed by the provision of specific morphogens and fate-specifying molecules18.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
