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.

Meis2 is essential for whisker development, independent of nerve involvement.

SOX11 and SOX4 help skin cells act like embryonic cells to heal wounds in mice.

Researchers developed a method to grow hair follicles using special beads that could help with hair loss treatment.

Researchers created human cells that can turn into sebocytes, which may help study and treat skin conditions like acne.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

The olfactory epithelium can regenerate throughout life, aided by specific cells, genes, and new research methods.
