Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

Multiphoton microscopy effectively images rabbit skin structures in detail without staining and shows differences from human skin.

3D bioprinting is advancing in plastic and reconstructive surgery, especially for creating tissues and improving surgical planning, but faces challenges like vascularization and material development.

3D bioprinting in plastic surgery could lead to personalized grafts and fewer complications.

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.

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

Scientists are using clumps of special stem cells to improve organ repair.

Basonuclin 2 is vital for the development of facial bones, hair follicles, and male germ cells in adult mice, and its absence can lead to dwarfism and abnormal follicles.

SLVs help maintain muscle stretch sensitivity and could aid in treating hypertension and muscle spasticity.

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

3D-printed membranes with smart sensors can greatly improve tissue healing and have many medical applications.

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

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

Understanding the properties of hyaluronic acid helps improve its use in facial aging treatments.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.

Young C57BL/6 mice heal better than BALB/c mice, and older mice heal faster but regenerate worse.

Direct excision techniques can rejuvenate the neck but may not enhance the jawline and could cause neck-face disharmony if done incorrectly.

Smart biomaterials that guide tissue repair are key for future medical treatments.

Bioinspired polymers are promising for advanced medical treatments and tissue repair.

Hydrogel composites have great potential in regenerative medicine, tissue engineering, and drug delivery.

The document concludes that mouse models are helpful but have limitations for skin wound healing research, and suggests using larger animals and genetically modified mice for better human application.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Changes in keratin make hair follicles stiffer.

The document concludes that understanding the anatomical changes of the ageing face is important for effective rejuvenation treatments.

Certain nutrients can help keep skin healthy as we age.

The document concludes that individualized reconstruction plans are essential for improving function and appearance after head and neck burns.

The document discusses a condition causing hair loss after surgery and a type of rosacea affecting the nose, with treatments including surgery and laser therapy.

The document describes various skin conditions, their features, and treatments but lacks detailed study size information.

Older adults often have skin problems due to aging, and treating these conditions requires attention to both physical and mental health.
