Ultra-high-frequency ultrasound effectively evaluates the impact of hyaluronic acid fillers in reducing nasolabial fold wrinkles over time.

Blue light can help treat skin conditions like eczema and acne without major side effects.

Treg cells help repair and regenerate tissues by interacting with local cells.

Human amniotic membrane helps heal skin wounds faster and with less scarring.

Optical imaging and light therapy show promise for diagnosing and treating liver injury caused by surgery.

Skin stem cells can help improve skin repair and regeneration.

Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.

Notch signaling disruptions can cause various skin diseases.

Gut microbes significantly affect brain steroid levels.

Tea, especially green tea, shows promise in cosmetics for skin and hair benefits but more research is needed for effective use.

Blocking DPP4 can potentially speed up hair growth and regeneration, especially after injury or in cases of hair loss.

Allopregnanolone can reduce gut inflammation and normalize neurotransmitter levels after finasteride withdrawal.

Short telomeres contribute to aging and cancer, and while telomerase can delay aging, it may also promote cancer.

Cell transplantation faces challenges in genitourinary reconstruction, but alternative tissue sources and microencapsulation show promise.

The osteopontin gene is active in a specific part of rat hair follicles during a certain hair growth phase and might affect hair cycle and diseases.

MicroRNAs could improve skin tissue engineering by regulating cells and changing the skin's bioactive environment.

Peptide-based hydrogels are promising for healing chronic wounds effectively.

A 3-month stay in space causes skin thinning, disrupts hair growth, and changes muscle-related genes in mice.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Wnt signaling is crucial for skin development and hair growth.

Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.

UV-induced autofluorescence is effective for identifying different types of alopecia.

Stromal stem cells may help heal wounds by becoming structural cells or affecting the immune system, but more research is needed to understand how.

Wool follicles are complex, involving interactions between different cell types and structures.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Platelet-rich plasma may improve healing and hair growth in cosmetic surgery but results vary.

Different types of sun exposure can damage skin cells and affect healing, with chronic exposure being more harmful, and certain immune cells help in the repair process.

Keratin from human hair shows promise for medical uses like wound healing and tissue engineering.
