“…In recent years, more and more molecular mechanisms of feather follicle development in poultry have been studied. For example, based on fluorescence quantitative PCR, Western blot and immunohistochemistry, the results showed that the melatonin receptor gene plays an important role in the development of feather follicles in goose skin ( Li, et al, 2022 ). Using Western blot, it was shown that methionine can promote feather follicle development in chicken embryos by activating the Wnt/β-catenin signaling pathway ( Chen, et al, 2020 ).…”
