Cell regeneration in epidermal tissue

"Cell regeneration in epidermal tissue" refers to the process by which the outermost skin layer replaces damaged or dead cells through the activation and differentiation of epidermal stem cells, particularly those in the basal layer and hair follicle niches[1][2][4][5][6]. This regeneration is tightly regulated by a balance between stem cell self-renewal and differentiation, coordinated by signaling pathways such as Wnt/β-catenin, transcription factors (MSX2, LEF1, TFAP2C), kinases like CDK9, and growth factor receptors including EGFR and FGFR. These pathways help restore skin integrity after injury and maintain the skin’s barrier function, but can also be implicated in diseases if their regulation is disrupted. Because "cell regeneration in epidermal tissue" describes a process and not a unique molecule, it cannot be mapped to a specific target for drug development[1][2][4][5][6].
