Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.

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

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Giving a special protein to dogs with a certain genetic disease improved their symptoms but didn't help with hair growth.

ICG-enhanced NIR laser therapy may be a promising acne treatment with improvement and no side effects.

5% minoxidil foam once daily works as well as 2% minoxidil solution twice daily for female hair growth and is more convenient.

Dutasteride 0.5 mg daily improves hair growth safely in men with hair loss.

Obesity increases the risk of developing polycystic ovary syndrome, and weight loss can improve the condition.

MDP hydrogel heals wounds faster and better than other treatments in diabetic mice.

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.

Memantine may slightly improve memory in people with Down syndrome, but more research is needed.

Inherited ichthyoses cause widespread skin scaling and thickening due to gene mutations.

Platelet-rich plasma may have some benefits in dermatology, but there's not enough evidence to widely recommend its use.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Advanced hydrogel systems with therapeutic agents could greatly improve acute and chronic wound treatment.

Doctors need to be better prepared to assess and treat obesity in patients.

Improving insulin sensitivity and weight loss can help manage polycystic ovary syndrome (PCOS).

Squarticles effectively deliver hair growth drugs to follicles and dermal papilla cells.

Nanoparticles can enter the skin, potentially causing toxicity, especially in damaged skin.

PCOS is often linked to insulin resistance and obesity, and weight loss can improve symptoms.

Using CRISPR for gene editing in the body is promising but needs better delivery methods to be more efficient and specific.

Nanoparticles around 600-700 nm can effectively enter and stay in hair follicles for days, which may help in delivering drugs to specific cells.

The article explains the genetic causes and symptoms of various hair disorders and highlights the need for more research to find treatments.

Products should be called 'sperm-safe' only after thorough, well-designed tests.

The document concludes that recognizing and properly diagnosing lipodystrophy syndromes is crucial for effective management and treatment.

The document concludes that while there are promising methods to control CRISPR/Cas9 gene editing, more research is needed to overcome challenges related to safety and effectiveness for clinical use.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Nanoparticles show promise for better wound healing, but more research is needed to ensure safety and effectiveness.
