Pregnancy can cause various skin changes and diseases, with PUPPP being the most common skin condition specific to pregnancy.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Current skin substitutes help heal severe burns but don't fully replicate natural skin features.

Inactive stem cells in hair follicles and muscles can avoid detection by the immune system.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Zinc is crucial for growth and health in rats.

Tributyltin exposure causes sex changes, sterilization, and decline in the snail Ocinebrina aciculata, risking its extinction.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Creating fully functional artificial skin for chronic wounds is still very challenging.

Fat cells in the skin help start healing and form important repair cells after injury.

Oral retinoids are effective for various skin conditions but have side effects and should not be used during pregnancy.

Drospirenone is a unique progestin with anti-water retention and potential blood pressure benefits, used in birth control and hormone therapy.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

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

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

Human hair follicle stem cells can turn into multiple cell types but lose some of this ability after being grown in the lab for a long time.

The study identified and characterized new keratin genes linked to hair follicles and epithelial tissues.

Advanced human skin models improve drug development and could replace animal testing.

Women with PCOS have fewer activated T cells in their ovarian follicles, which might affect fertility.

Microneedles are effective for painless drug delivery and promoting wound healing and tissue regeneration.

Different methods of preparing Platelet-Rich Plasma (PRP) can affect wound healing and hair regrowth in plastic surgery. Using a kit with specific standards helps isolate PRP that meets quality criteria. Non-Activated PRP and Activated PRP have varying effects depending on the tissue and condition treated. For hair regrowth, Non-Activated PRP increased hair density more than Activated PRP. Both treatments improved various aspects of scalp health.

Vitamin D receptor is crucial for starting hair growth after birth.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

Low doses of mixed chemicals cause permanent reproductive malformations in male rats.

Bismuth subgallate and borneol together improve skin wound healing better than when used separately or compared to other treatments.

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

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

Certain skin conditions may indicate or increase the risk of Parkinson's disease.
