Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

Over one-third of women experience hair loss, with female-pattern hair loss being most common, and treatments include minoxidil and possibly hair transplantation.

Removing both Atr and Trp53 genes in adult mice causes severe tissue damage and death due to DNA damage.

No treatment fully prevents hair loss from chemotherapy yet.

ADSC-CM treatment improved hair density and thickness in women with hair loss, safely and effectively.

Low iron levels are not directly linked to chronic hair loss and iron supplements may not help.

Fat tissue stem cells may help increase hair growth.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Hair grays due to oxidative stress and fewer functioning melanocytes.

Some breast cancer chemotherapy can cause permanent hair loss.

Stress can worsen skin conditions by affecting hormone levels and immune response.

Scalp cooling can prevent chemotherapy-induced hair loss, and certain treatments can speed up hair regrowth, but more research is needed for better treatments.

Scalp cooling can reduce chemotherapy-induced hair loss and should be available in all hospitals.

Albendazole treatment for echinococcosis can cause serious side effects and requires close monitoring.

Chemotherapy can cause permanent, non-reversible hair loss similar to pattern baldness.

Chemotherapy can cause various skin problems, and recognizing them helps improve patient care.

Scalp cooling significantly reduces hair loss in chemotherapy patients.

Exosomes can improve skin health and offer new treatments for skin repair and rejuvenation.

Fetal cells could improve skin repair with minimal scarring and are a potential ready-to-use solution for tissue engineering.

Cyclophosphamide has serious side effects, but long-term follow-up can help manage risks.

Using steroids can increase the risk of heart problems.

Low dose oral minoxidil helps regrow hair in permanent chemotherapy-induced alopecia.

Sarcoptes scabiei infection causes significant health and behavior changes in wombats.

Some breast cancer patients developed permanent hair loss after chemotherapy and hormonal therapy, showing patterns similar to common baldness and alopecia areata.

Melatonin protects skin against UV damage by regulating various cellular processes.
