hair follicle epithelial cells mesenchymal cells growth factors cell adhesion molecules

TLDR Hair follicles create different cell layers and proteins, controlled by various molecules.

The mammalian hair follicle, composed of uniform epithelial and mesenchymal cells, was found to produce multiple concentric cylinders of distinct cell types, each synthesizing unique proteins. Evidence suggested that various growth factors, cell adhesion molecules, and other molecules played crucial roles in regulating this complex organ.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 3 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
