TLDR Porcine skin varies by region, affecting its use as a human skin model.

The study evaluated the histological structure of porcine skin from 11 different anatomic regions in the American Yorkshire crossbreed, focusing on epidermal and dermal thickness, hair follicle density, and collagen and elastin composition and distribution. Significant regional differences were found, particularly in dermis and epidermis thickness and collagen and elastin content. Variations in type I and type III collagen distribution were also observed. These findings underscored the importance of recognizing regional differences in porcine skin to prevent misinterpretation when using it as a model for human skin.

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

in Research 830 upvotes 1 year 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.
