May 2015 in “Cell Stem Cell” Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

January 2016 in “Development” The study demonstrated that the transcription regulators YAP and TAZ were essential for maintaining skin homeostasis by promoting the proliferation of basal layer stem/progenitor cells. In both mouse and human skin, YAP and TAZ localized in the nucleus of basal layer cells, regulated by integrin-Src signaling. Deletion of YAP and TAZ in mice resulted in slowed cell proliferation, hair loss, and impaired wound healing, underscoring their role in skin regeneration. The research highlighted the importance of integrin-Src and EGFR-PI3K signaling pathways for YAP nuclear localization, which was crucial for cell cycle progression and growth. Additionally, YAP acted as a sensor of epithelial cell polarity, with its localization influenced by apical-basal polarity signals. These findings provided insights into the molecular mechanisms of skin renewal and the potential impact of YAP and TAZ on skin-related conditions and cancer.
