[Functional study of the regeneration of nerve fibers after keratinocyte transplantation].

The functional regeneration of sensory nerves was investigated in 5 patients with skin defects (caused by leg ulcers, a burn or fasciitis necrotisans) after transplantation with a keratinocyte suspension. In this area, first the pain sense and soon after wards the cold and heat sense returned, followed finally by the flare reaction caused by the mustard oil test. No sweat production could be observed during the study, because sweat glands were not found after the keratinocyte transplantation. The reinnervation course is roughly the same for skin defects covered with split skin graft or with a keratinocyte suspension.
