Birth control pills with low-dose estrogen and antiandrogenic progestins can effectively treat acne.

Histopathology is not reliable for detecting early fibrosis in traction alopecia or for showing how severe it is.

Androgens can cause hair growth in some areas but hair loss on the scalp.

New treatments for prostate cancer and BPH show promise, including novel compounds that target hormone synthesis and response.

Key genes can rewire networks, changing skin appendage types.

Tributyltin exposure causes sex changes, sterilization, and decline in the snail Ocinebrina aciculata, risking its extinction.

High doses of cobalt stopped hair growth in rabbits.

The Brazilian Society of Dermatology agrees that oral isotretinoin is effective for acne and other skin conditions, and it's safe when monitored, but more research is needed on dosing and duration.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

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

Certain mature cells in mouse lungs can turn back into stem cells to aid in tissue repair.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

A new protein was made to detect specific skin cell growth receptors and worked in normal skin but not in skin cancer cells.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

Macrophage-stimulating protein helps hair grow and can start hair growth phase in mice and human hair samples.

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.

A peptide called DPS-1 helps human scalp cells grow and stimulates hair growth in mice.

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.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

The document concludes that immune system abnormalities cause alopecia areata, but the exact process is still not completely understood.

Integrin alphavbeta6 is important for wound healing and hair growth, and blocking it may improve these processes.

Innate lymphoid cells help control skin bacteria by regulating sebaceous glands.

The method increases stem-like cells for better skin regeneration.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

PRC1 is essential for proper skin development and stem cell formation by controlling gene activity.

COVID-19 may affect male fertility and women might have better outcomes due to hormonal and immune differences.

N-acetyl-L-cysteine (NAC) can prevent DNA damage and protect cells from harm.

Dermal papilla cells help wounds heal better and can potentially grow new hair.

Merkel cells may have roles in sensing magnetic fields, creating fingerprints, Reiki energy healing, passing on environmental information to offspring, and influencing hair shape.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.
