New findings suggest targeting IL-23 could treat psoriasis, skin cells can adapt to new roles, direct conversion of skin cells to blood cells may aid cell therapy, removing certain tumor cells could boost cancer immunotherapy, and melanoma may have many tumorigenic cells, not just cancer stem cells.

Fetal scalp cells have more regenerative genes than adult cells, and decellularized muscle matrix is better for muscle repair than commercial alternatives.

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

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

A specific group of stem cells can help regenerate hair continuously.

CD34+ cells from fat tissue help form hair follicles and blood vessels in skin.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

The circadian clock in skin cells controls their growth and rest cycles.

Trichoblastomas may mimic fetal skin development by having many Merkel cells, unlike adult skin.

Human hair cells can change based on their environment, especially interactions with certain skin cells.

DS cells in hair follicles can help form and restore hair, especially in hair loss conditions.

A new imaging technique can observe stem cells in living mice without harming them.

Different materials affect the growth of brain cells and fibroblasts, with matrigel being best for brain cell growth.

Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

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

Hair follicle stem cells have greater longevity and adhesion, while transit-amplifying cells are more mobile.

Transplanted bone marrow cells actively move, form clusters, and grow after transplantation.

Ectomesenchyme is a key source of skin stem cells.

Ancient immune and signaling pathways still regulate blood cell development.

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 control their future role by changing ERK signal timing, affecting tissue regeneration and cancer.

The mTurq2-Col4a1 mouse model shows that cells can divide while attached to stable basement membranes during development.

Human skin cells with stem-like features can help create new hair follicles and sebaceous glands when combined with other cells.

3D cell-derived matrices improve tissue regeneration and disease modeling.

Basal stem cells in the skin have distinct types that are crucial for skin structure and health.

Dermal papilla cells can help form hair-like structures in lab-grown skin cells.

Lower proximal cup cells, not bulge stem cells, regenerate hair follicles after chemotherapy.

Skin-derived precursors in hair follicles come from different origins but function similarly.

A new method efficiently creates cell spheres that help regenerate hair.
