Dental pulp stem cells might not reliably become neurons.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

Fibroblasts are crucial for tissue repair and inflammation, and understanding them can help treat fibrotic diseases.

Wnt signaling may be linked to heart diseases in aging and could be a target for future treatments.

Small molecule IM boosts hair growth by changing stem cell metabolism.

Cells from certain embryo parts can induce head formation in another embryo, involving complex signaling pathways.

Benign skin tumors need accurate diagnosis to ensure proper treatment.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Special fiber materials boost the healing properties of certain stem cells.

Low-oxygen conditions and ECM degradation products increase the healing abilities of perivascular stem cells.

Different types of fibroblasts play various roles in both healthy and diseased tissues, and understanding them better could improve treatments for fibrotic diseases.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Organs like hair follicles can renew themselves in complex ways, adapting to different needs and environments.

Intestinal stem cells can help repair skin damage from radiation.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

Scientists identified a unique type of human skin stem cell that could help with tissue repair.

Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Stem cell-derived conditioned medium shows promise for treating various medical conditions but requires standardized production and further validation.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Potassium channel openers are effective in treating heart conditions, high blood pressure, pulmonary diseases, bladder issues, and hair loss, but more selective drugs are needed.

The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Testosterone supplements can increase muscle mass and strength in older men with low levels, but long-term effects and risks need more research.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

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.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.
