Following publication of the original article, the authors regret that the images in Fig. 5B are incorrect. Upon re-examination of the original data, Fig. 5B was inadvertently presented incorrectly during the manuscript preparation process.

Fig. 5.

FT/CL hydrogel treatment group showed better improvements on wound healing and behavioral evaluations of acid-induced oral ulcer (OU). A An illustrative diagram showing the wound creation and subsequent healing stages. B Representative images of tongues within 7 d. The white line indicates the specific wound on the tongue. C An illustrative diagram and the number (D) of facial wiping during a 3-min block on days 1, 2, and 3. ^*, comparison between the Ctrl and FT/CL groups. E An illustrative diagram and the number (F) of mouth rubbing during a 3-min block on days 1, 2, and 3. ^*, comparison between the Ctrl and FT/CL groups. G Changes of body weight compare to day 0 after acid stimulation. H Macroscopic scores evaluating the clinical severity of OU. In all experiments, data were presented as mean±SD for n = 3 biological replicates. ^*p < 0.05, ^**p < 0.01, ^***p< 0.001, ^****p < 0.0001

The original article has been corrected.

For completeness and transparency, the correct and old incorrect versions of Fig. 5 are displayed below.
