The document tests knowledge and decision-making in hematology through multiple-choice questions.

The research found that people's hair proteins vary by individual and body part, with some differences between ethnic groups, which could help in forensics.

Maintaining DNA integrity in stem cells is crucial to prevent aging and cancer.

Nerves are crucial for the regeneration of various body parts in many animals.

Fibroblast state switching is crucial for skin healing and development.

Wounded skin cells can revert to stem cells and help heal.

Chick embryo extract helps rat hair follicle stem cells potentially turn into Schwann cells, important for the nervous system.

Different immune cells like platelets, mast cells, neutrophils, macrophages, T cells, B cells, and innate lymphoid cells all play roles in skin wound healing, but more research is needed due to inconsistent results and the complex nature of the immune response.

The research identifies genes linked to wool quality in sheep and provides insights to improve wool production.

Odontogenic keratocysts are caused by abnormal Hedgehog signaling and can lead to tooth and bone issues.

ILC1-like cells may contribute to hair loss in alopecia areata and could be new treatment targets.

Hair can regrow in adult mice's skin after injury, and this regrowth doesn't come from existing hair cells but from skin cells in the wound, with Wnt7a protein helping this process. This could help treat baldness and scarring.

FGFR2 signaling controls Merkel cell formation in different skin regions.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

Wounds can cause new hair growth in adult mice, influenced by Wnt signaling.

The research showed how melanocytes develop, move, and respond to UV light, and their stem cells' role in hair color and skin cancer risk.

Hair follicle stem cells can form both hair follicles and skin.

Cells with active Wnt signaling are less likely to turn into cancer when exposed to a cancer-causing gene.

Female cuckoo color differences are linked to their unique genes and help avoid male harassment.

Bone-forming cells grow well in 3D polymer scaffolds with 35 µm pores.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

PRP injections may improve hair thickness and density in female hair loss patients.

Sp6 promotes tooth development by reducing follistatin levels.

Human scalp fat stem cells showed improved cartilage-like development on a special scaffold with freeze-thaw treatment.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Alopecia in captive rhesus macaques is affected by season, sex, age, housing, and stress, with complex links between stress hormones and hair loss.

Hair follicle hyperplasia is common in both benign and malignant skin lymphoproliferative disorders, with a proposed new term "pseudolymphomatous adnexitis."

Prenatal stress changes how male and female rats enjoy rewards differently, linked to sex hormones.

HPV genes in mice improve ear tissue healing by speeding up skin growth and repair.
