Nerves are crucial for the regeneration of various body parts in many animals.

Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Loss of Msx2 function causes eye development issues similar to Peters anomaly.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Mice can regenerate ear tissue without the p53 protein.

African spiny mice can regenerate skin, hair, and cartilage, but not muscle, and their unique abilities could be useful for regenerative medicine.

The immune system plays a key role in tissue repair, affecting both healing quality and regenerative ability.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

Different species use the same genes for tooth regeneration.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.

Oral minoxidil 5 mg daily increases hair growth safely in men with hair loss, with minor side effects.

Using a strong allergy medicine too often on the scalp can cause swelling and inflammation.

Testosterone is key for male sexual function, and treating hormone imbalances can improve sexual issues.

HPV genes in mice improve ear tissue healing by speeding up skin growth and repair.

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

Drug advertising has greatly increased, changing consumer behavior and raising concerns about its influence on healthcare and patient protection.

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 document concludes that rapid identification, isolation, and strict infection control are crucial to manage SARS outbreaks.

Fadrozole and finasteride change gene expression related to sex hormones and thyroid hormones in frog larvae development.

MRL/MpJ mice's skin wounds heal with scars, unlike their ear wounds which can regenerate.

Wnt10b helps blood stem cells grow after injury.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

BMP2 needs periosteal tissue to help regenerate mouse middle finger bones within a specific time.
