Gustatory-neuron-supplied R-spondin-2 is required for taste bud replenishment.
Article in Stem cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Replenishment of taste cells in taste buds throughout life requires innervation. Recently, we provided evidence that R-spondin is sufficient to promote taste cell generation and restore taste buds in a nerve transection model. Yet, the necessity of gustatory-neuron-supplied R-spondin 2 (RSPO2) in taste tissue homeostasis has remained unresolved. We used genetic approaches to investigate this. In a strain that carries an Rspo2 hypomorphic allele, the number of taste buds was significantly reduced in these mice, compared to wild-type mice, in both anterior and posterior tongue. Specific ablation of Rspo2 in the nodose-petrosal-jugular ganglion complex in another mouse strain led to nearly complete loss of taste buds in the circumvallate papilla. Epithelial ablation of Rnf43/Znrf3, the activity of which is antagonized by R-spondin binding, led to exuberant, sustained expansion of taste buds. Thus, our data strongly support that the RSPO2-RNF43/ZNRF3 axis serves as a master regulator for taste tissue homeostasis.
