Mesenchymal stromal cells may help treat severe COVID-19, but more research is needed to confirm their effectiveness.

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.

Researchers isolated a new type of stem cell from mouse skin that can renew itself and turn into multiple cell types.

Epidermal stem cells have potential for personalized regenerative medicine but need careful handling to avoid cancer.

Exosomes from umbilical cord cells fix hearing loss and damaged ear hair cells in mice.

The technique allowed noninvasive tracking of hair stem cell survival and growth, showing potential for hair loss research.

Injected cells show potential for hair growth.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Keratinocyte stem cells are crucial for skin renewal and have potential in wound healing and tissue regeneration.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

RCS-01 therapy is safe and may improve skin structure by affecting gene expression.

Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

Melanocyte stem cells in hair follicles are key to understanding and potentially preventing hair graying.

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.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Eating less can slow aging and help keep stem cells healthy by cleaning out damaged cell parts.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Eating fewer calories improves the ability of stem cells to repair and renew the body in various tissues.

Blood stem cells are diverse, influenced by many factors, and understanding them is key for progress in regenerative medicine.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

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

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Stem cells are more dynamic and adaptable than previously believed.

Skin stem cells remember past inflammation, helping them respond better to future injuries and possibly aiding in treating skin issues.

Wharton's jelly secretomes are best for promoting blood vessel growth.
