Moreover, the dermal-epidermal junction was aligned to the crypts of the former intestinal tissue that results in topography comparable to the dermal papillae
of human skin.
Scientists harvested dermal papillae
from seven human donors, cloned them in the laboratory, and transplanted them into human skin grafted on to the backs of mice.
They noticed that rodent hair was easily transplantable as their dermal papillae
aggregate or form clumps in the tissue culture.
The authors said neonatal foreskin was selected because it is non-hair bearing tissue, which would challenge the human dermal papillae
that control hair follicle growth "not just to contribute to hair follicles within the skin, but rather, to fully reprogram the recipient epidermis to a follicular fate.
and elastic fibers are absent and blood vessels are mal-developed.
Use of transparent film dressings may also result in excessive moisture and exacerbate the separation of the dermis from the dermal papillae
Similar results were also obtained in in vivo dermal papillae
of human scalps.
In addition, the dermal friction ridge detail is recorded as double rows of dermal papillae
compared to epidermal friction ridge detail, which is recorded as single ridge units.
The hallmark of dermatitis herpetiformis (DH) is granular IgA in the dermal papillae
