ABSTRACT
Enormous advances in the development of skin substitutes have occurred over the past
3 decades. There are numerous commercially available skin substitutes, some of which
can provide permanent dermis or epidermis. Unfortunately, no product available can
permanently replace both dermis and epidermis in a single-stage application procedure.
Several investigators have reported promising strategies for permanent skin replacement
using a wide variety of components and culturing techniques. Obstacles to overcome
in the quest for an ideal skin substitute include epidermal antigenicity, scarring,
contraction, pigmentation, and loss of adnexal structures. The development, indications,
and shortcomings of several currently used skin substitutes and promising experimental
strategies are reviewed. The future direction of tissue-engineered skin substitutes
is addressed with a focus on overcoming the current obstacles.
