Did you mean Basal Keratinocytes?

GlossaryBasal Keratinocytes

cells in the skin's lowest epidermal layer producing keratin

Basal keratinocytes are the cells located in the lowest layer of the epidermis, which is the outermost layer of the skin. These cells are responsible for producing keratin, a protein that helps protect the skin and underlying tissues. They also play a crucial role in skin regeneration by continuously dividing and pushing older cells towards the surface, where they eventually shed.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 2 years 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.
