DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

Diet changes can protect against harmful environmental effects on fetal development.

ATP-dependent chromatin-remodeling complexes are crucial for gene regulation, cell differentiation, and organ development in mammals.

Hormone treatments for transgender individuals generally improve mental health and physical transition, with some health risks that require medical supervision.

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.

Stem cell self-renewal is complex and needs more research for full understanding.

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.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

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

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

Mutant CDP/Cux protein causes hair defects and reduced male fertility in mice.

Certain genetic variations in the AR and ERβ genes can affect androgen levels in women.

The Wnt/β-catenin pathway is important for tissue development and has potential in regenerative medicine, but requires more research for therapeutic use.

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

The tumor suppressor gene FLCN affects mitochondrial function and energy use in cells.

Certain mice without specific receptors or mast cells don't lose hair from stress.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.

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

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Inactive hair follicle stem cells help prevent skin cancer.

Researchers found 63 genes linked to male-pattern baldness, which could help in understanding its biology and developing new treatments.

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

There are still challenges in diagnosing and treating chronic skin diseases, but there is hope for future improvements.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.
