Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

Testosterone and dihydrotestosterone can slow down the growth of certain hair follicle cells.

Improving dermal papilla cells can help regenerate hair follicles.

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

Calcium signals and SHH guide the direction of feather growth in chicken skin.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

Using stem cells from fat tissue can significantly improve wound healing in dogs.

Hair follicle development involves complex interactions between skin layers and cells, but many details are still unknown.

Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Researchers created a 3D-printed skin model that grew human hair when grafted onto mice by improving blood supply to the grafts.
