IL-1 receptor absence in mice leads to skin cysts and changes in immune response after UVB exposure.

The document reports a rare case of ECCL with a new association with optic disc colobomas.

Sweat duct differentiation in trichilemmal cysts is very rare and can be successfully removed with surgery.

Thymoma in cats can cause hair loss without inflammation.

A postmenopausal woman's high testosterone levels and symptoms improved after removing a tumor from her ovary.

Neotropical porcupines can get co-infected with poxvirus and Toxoplasma gondii.

A young woman with a rare skin cancer was diagnosed late because her symptoms were unusual for the disease.

An infant with complete hair loss was diagnosed with a genetic disorder affecting hair growth.

Diagnosing oral ulcers can be complex and requires careful examination and follow-up.

Removing hair wrapped around the labia quickly prevents serious tissue damage.

Modified β-catenin can cause different effects in mouse skin cells, leading to cysts or tumors depending on the cell type.

Treatments for hair loss include estrogen therapy and special shampoos.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

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.

Targeting colon cancer stem cells might lead to better treatment results.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Stem cells are crucial for tissue growth, cancer treatment, and disease modeling, but challenges remain in clinical use.

Lower proximal cup cells, not bulge stem cells, regenerate hair follicles after chemotherapy.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

The skin has different types of stem cells that can repair and regenerate tissue.

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.

A specific group of stem cells can help regenerate hair continuously.

Hair follicle stem cells can turn into various cell types and help repair nerves.

New techniques have enhanced our understanding of how stem cells function and the role of mutations in aging tissues, which may influence future cancer therapies.

Stem cells in the skin help with healing and can also lead to cancer.

Mesenchymal stem cells could help treat radiation-induced bladder damage but more research is needed to overcome current limitations.

Hair follicle stem cells are key for hair growth and skin repair.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.
