Retinoic acid can either maintain stem cells or make them specialize, depending on the cell type.

Cell size independently controls when stem cells divide.

Active and quiescent stem cells work together in mammals to maintain and repair tissues.

Epidermal signaling helps regenerate fingertip tissue.

PRC1 influences skin stem cell development by both turning genes on and off, affecting hair growth and skin cell types.

Human melanocytes have unique traits that affect melanoma development and prognosis.

HBCs in the olfactory epithelium can self-renew or differentiate into other cell types, with specific patterns during regeneration.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Tooth-derived stem cells show promise for regenerating gum tissue but need standardized selection methods.

Mouse hair follicle stem cells have a flexible chromatin state that supports skin health and hair growth.

Non-hairy skin cells might be used to regenerate hair, helping with baldness and skin wounds.

Hair follicles can be a good source of stem cells like those from bone marrow.

A new 3D culture system helps grow and study mouse skin stem cells for a long time.

Organoid technology is improving personalized medicine by better predicting drug responses and treatments.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.

Intu gene is crucial for hair follicle formation by helping keratinocytes differentiate through primary cilia.

Human hair follicle cells can be turned into neural stem cell-like cells, which might help treat brain diseases.

Stem cells can help regenerate hair follicles.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Mesenchymal cells are essential for hair follicle stem cell growth.

Human hair matrix cells and dermal papilla fibroblasts can form early hair follicle structures but don't produce hair shafts yet.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Younger mice's hair-follicle stem cells are better at turning into heart cells than older mice's.

3D-cultured dermal papilla cells are better at inducing hair follicles than adipose-derived stem cells.

Polycomb Repressive Complex 1 is crucial for keeping stem cells stable and maintaining healthy adult tissues.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Stem cell behavior varies with stimuli, and lineage changes can happen without affecting stem cell division.

The research mapped gene activity in developing mouse skin and found key markers for skin cell types and changes from fetal to early postnatal stages.

Adult skin cells can be used to create new hair in a lab.
