Blood stem cells are diverse, influenced by many factors, and understanding them is key for progress in regenerative medicine.

A critically ill boy experienced hair loss likely due to the stress of his medical treatments, but his hair regrew completely in 1.5 months.

Chemotherapy and radiotherapy can cause skin side effects like rashes, hair loss, and nail changes, which are usually managed with conservative treatments.

The document suggests a possible link between mast cells and scarring alopecia, recommending more research for potential treatments.

Chemotherapy often causes hair loss, which usually grows back within 3 to 6 months, but there's no effective treatment to prevent it.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Ripretinib is effective and safe for treating advanced GIST in Chinese patients, particularly for non-gastric GISTs.

New cancer treatments are less harmful to hair but can still cause hair loss, color, shape, and growth changes.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Understanding skin structure and development helps diagnose and treat skin disorders.

The protein Gnαs is found more in black mice than white mice and may influence their coat color.

Treating melasma in men is difficult, especially for the deeper skin layers, and may need more than just topical treatments.

Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

Melanocyte-associated antigens may play a key role in alopecia areata and could be targets for new treatments.

New therapies show promise for wound healing, but more research is needed for safe, affordable options.

Acitretin treatment unexpectedly darkened a patient's gray hair.

Using radiation to make mice's hair turn gray helps study and find ways to prevent or reverse hair graying.

Most pediatric cancer patients in the study developed skin problems, often due to their cancer treatment.

Lenalidomide helps hair follicle stem cells turn into melanocytes, which may improve repigmentation in vitiligo.

A group has developed therapies that show promise for treating cancer and various other conditions.

Hair greying is seen as a sign of aging; temporary fixes like hair dye are used, but a balanced diet and hair care can help manage it.

ILC1-like cells can cause alopecia areata by attacking hair follicles.

Skin lesions in Carney complex are likely caused by a specific group of skin cells that promote pigment production due to a genetic mutation.

Lamivudine might reverse hair graying and needs more research for potential treatments.

Estrogens and progesterone are key in regulating melasma pigmentation.

A specific immune response helps control mite populations on the skin, maintaining healthy hair follicles.

New treatments and diagnostic methods for various animal skin conditions showed promising results.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Lichen planopilaris and frontal fibrosing alopecia are likely the same disease with different clinical appearances.
