It consists of devitalized tissue that dries, darkens, and separates as inflammatory cells create a boundary between the stump and the abdominal wall. Until the umbilicus is epithelialized, the underlying vessels and tissue planes provide a route for infection to spread, so a small change in the surrounding skin can carry more significance than the appearance of the drying stump itself.
