New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

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.

Treating psoriasis on the scalp, nails, and skin folds is challenging, often requiring systemic treatments for severe cases, with some success in topical and biologic treatments.
