The developmental basis of fingerprint pattern formation and variation
Open accessAbstract
Fingerprints are complex and individually unique patterns in the skin. Established prenatally, the molecular and cellular mechanisms that guide fingerprint ridge formation and their intricate arrangements are unknown. Here we show that fingerprint ridges are epithelial structures that undergo a truncated hair follicle developmental program and fail to recruit a mesenchymal condensate. Their spatial pattern is established by a Turing reaction-diffusion system, based on signaling between EDAR, WNT, and antagonistic BMP pathways. These signals resolve epithelial growth into bands of focalized proliferation under a precociously differentiated suprabasal layer. Ridge formation occurs as a set of waves spreading from variable initiation sites defined by the local signaling environments and anatomical intricacies of the digit, with the propagation and meeting of these waves determining the type of pattern that forms. Relying on a dynamic patterning system triggered at spatially distinct sites generates the characteristic types and unending variation of human fingerprint patterns.

scRNA-seq enables profiling of gene expression at single-cell resolution and identification of reliable cellular heterogeneity, allowing identification of previously unrecognized heterogeneity, revealing regulatory relationships between genes, and tracking trajectories of distinct cell lineages.
“It enables both profiling of gene expression measurements at a single-cell resolution and identification of reliable cellular heterogeneity, allowing for the identification of previously unrecognized levels of cellular heterogeneity, revealing regulatory relationships between genes, and tracking the trajectories of distinct cell lineages in the same or different developmental stages [63–66].”
From Diversity of human skin three-dimensional organotypic cultures (2024) · cites this paper as [63]
In “Single cell expression profiling delineates shared early but distinct late events,” the paper uses single-nucleus RNA-seq to characterize gene expression and identify distinct cell populations. The methods section also describes pseudotime trajectory analysis. It does not establish that this sequencing analysis revealed regulatory relationships between genes or tracked lineages across different developmental stages; the sequenced skin was from week 14.

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.
