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.

The document concludes that identifying the specific cells where skin cancers begin is important for creating better prevention, detection, and treatment methods.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Different processes create patterns in skin and things like hair and feathers.

No link between scalp patterns and alopecia severity in children, but more severe cases often had nail abnormalities.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.

Certain transcription factors are key in controlling skin stem cell behavior and could impact future treatments for skin repair and hair loss.

The document reviews various hair and nail disorders, their causes, and treatments, emphasizing the need for proper diagnosis and the link between nail changes and systemic diseases.

The conclusion is that a systematic approach is key for treating symmetrical alopecia in dogs, but treatment may not always be necessary.

Indian Hedgehog helps control skin cell growth and protects against aggressive skin cancer.

Increasing Wnt5a in mice skin delays hair growth but doesn't stop it.

Budesonide and N-acetylcysteine reduced tumors and alopecia in mice, regardless of FHIT gene status.

The project created a standardized system for classifying skin lesions in lab rats and mice.

Adult stem cells are important for tissue repair and have therapeutic potential, but more research is needed to fully use them.

TGM3 is important for skin and hair structure and may help diagnose cancer.

Hair follicles in the back of the rosette fancy mouse have reversed orientations due to a gene mutation.

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

AiQingHua oil improves blood flow and promotes hair growth in mice.

Skin patterns form through molecular signals and genetic factors, affecting healing and dermatology.

The CUBIC protocol allows detailed 3D visualization of proteins in mouse skin biopsies.

Calorie restriction changes the elemental and isotopic makeup of mouse hair and bone.

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

Some masked palm civets in Japan have a skin disease caused by mites.

Oral cyclosporin doesn't stop hair loss.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.

MRL/MpJ mice's skin wounds heal with scars, unlike their ear wounds which can regenerate.

Significant progress was made in understanding PXE, but effective treatments are still needed.

The document concludes that inflammation markers can be used in diabetes, vitamin D3 affects immune pathways, hyperthyroidism changes hormone levels, androgen levels help diagnose Adrenocortical Carcinoma, erectile dysfunction is linked to diabetes, hypogonadism is common in HIV-infected males, and hormones can be biomarkers for various conditions.

Both cell and non-cell parts are important for rat whisker follicle regrowth.
