Meibomian glands are highly specialized and differ significantly from other sebaceous glands in structure and function.

Dogs could be good models for studying human hair growth and hair loss.

New technologies show promise for better hair regeneration and treatments.

Cyclooxygenase-2 overexpression in mice skin causes hair loss like human androgenetic alopecia.

Different Myc family proteins are located in various parts of the hair follicle and may affect stem cell behavior.

VEGFR-2 is active in hair follicles, sebaceous glands, sweat glands, and skin on the human scalp.

Researchers created a skin treatment that could effectively deliver medication into hair follicles.

PGD2 stops hair growth and is higher in bald men with AGA.

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.

Using neurohormones to control keratin can lead to new skin disease treatments.

High proliferative activity and peripheral invasion indicate malignancy in canine sebaceous gland tumors; the term 'epithelioma' should be updated for clarity.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

CYP2B12 enzyme in skin cells converts arachidonic acid into specific bioactive lipids.

Androgens play a complex role in skin conditions like acne and hair loss in women, and normal blood levels don't always show true androgen status.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Single Blimp1+ cells can create functional sebaceous gland organoids in the lab.

People with alopecia areata have higher levels of RBP4 protein and antibodies against it.

Acne is linked to inflammation and insulin resistance, and is associated with various syndromes that require different treatments.

Green tea extract increases lipid production in human sebaceous gland cells.

Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.

Botulinum toxin has potential for treating various skin conditions and improving wound healing.

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.

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.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

Prolactin may play a significant role in skin and hair health and could be a target for treating skin and hair disorders.

Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.

Mutations in the P2RY5 gene cause hereditary woolly hair.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Probiotic bacteria improved skin and hair health in aged mice.

Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.
