    TLDR WHV infection does not affect woodchuck skin anatomy.
    The study examined the microscopic anatomy of the skin in 33 woodchucks, comparing those infected with woodchuck hepatitis virus (WHV) to non-infected ones. It included 17 healthy non-infected adults, 10 infected adults, 4 non-infected neonates, and 2 infected neonates. No histological differences were found based on sex, age, or WHV infection status. The skin thickness averaged 2394 microns, with the thickest areas on the dorsal body. The epidermis had 4 layers, with a stratum lucidum only in footpads. The dermis showed no clear distinction between superficial and deep layers, but elastic fibers were more prominent superficially. Hair follicles were mostly compound, and sebaceous glands were associated with hair follicles. No apocrine sweat glands were found, but eccrine sweat glands were abundant in the footpads.

      community How true is the statement: dead follicles don't grow back?

      in Research/Science  107 upvotes 10 months ago
      Hair follicles usually go dormant rather than die, and treatments like finasteride, minoxidil, and hormone therapy can sometimes reactivate them, though results vary. Complete regrowth is rare, especially in long-term bald areas, but some individuals see significant improvement with these treatments.
