Conditioned media from mesenchymal stem cells show promise for tissue repair and disease treatment, but more research is needed on their safety and effectiveness.

Transit-amplifying cells are crucial for tissue repair and can contribute to cancer when they malfunction.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

α-parvin is necessary for skin and hair growth and for the correct orientation of skin cells.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.

Ganoderma lucidum extract may help treat stress-related hair loss.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

After skin is damaged, noncoding dsRNA helps prostaglandins and Wnts work together to repair tissue and promote hair growth.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

A protein from certain immune cells is key for new hair growth after skin injury in mice.

Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Proper niche formation in Drosophila requires Slit-Robo signaling for cell migration.

Using buccal mucosa for hypospadias repair in children is effective and reduces complications.

Targeting lipid metabolism can help treat advanced, resistant cancers.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Using systemic drugs as creams for skin conditions shows promise, but more research is needed to confirm their effectiveness and safety.

Human dermal fibroblasts help microvascular endothelial cells grow, but not vice versa.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.

Spironolactone may help improve symptoms and tear quality in dry eye disease.

Combining specific inducers helps dermal papilla cells regain hair-forming ability.

A protein called desmoglein 3 is important for keeping hair follicle stem cells inactive and helps in their regeneration.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Skin cancer often starts from Lgr5+ progenitor cells.

Some growth factors, while important for normal body functions, can cause diseases when not regulated properly.

PRP helps skin heal, possibly through special cells called telocytes.

A virus protein can activate a pathway that may lead to abnormal hair follicle 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.
