Fig. 4. The signaling pathways involved in p63-mediated stemness regulation.
A The Notch (left), Wnt/β-catenin (middle), and Hh (right) pathway components modulated by p63 isoforms during ESCs’ stemness regulation. All the encircled numbers indicate p63 isoform contribution by transcription regulation. B The reciprocal miRNA-p63 interactions are a vital factor in modulating p63 function, which is extensively involved in the development of the skin epidermis, including epithelial cell proliferation, differentiation, and senescence. C p63 regulates the stemness of ESCs through the signal molecules associated with epigenetic modifications. D ΔNp63 controls the stemness of ESCs by regulating cell adhesion molecules. E Other signaling involved in p63-mediated modulation of ESCs’ stemness. As shown, ΔNp63 is the most studied isoform and it is involved in various cell mechanisms to achieve self-renewal and differentiation control of ESCs.
