Revision abdominoplasty and proper umbilical positioning.

In the last decade, body contour surgery has advanced substantially. Abdominoplasty is the most frequent procedure in body contour aesthetic surgery. The surgeon who performs body rejuvenation procedures needs knowledge of anatomic, technical, and artistic concepts to assess and resolve the full spectrum of trunk deformities.

Functional characterization of highly adherent CD34+ keratinocytes isolated from human skin.

Compared to murine models, data on cells responsible for the homeostasis of human epidermis are scarce and often contradictory. Given the conflicting results and the availability of clinical grade protocols to purify CD34 cells from a given tissue, we pursued to phenotypically characterize human epidermal CD34+ population. After magnetic separation of whole skin CD34+ and CD34- cell fractions and selection for cells highly adherent to extracellular matrix, both CD34+/- fractions retained the ability to form a stratified epidermis in organotypic cultures and presented similar in vitro migratory phenotypes.

Age-dependent depletion of human skin-derived progenitor cells.

A major unanswered question in autologous cell therapy is the appropriate timing for cell isolation. Many of the putative target diseases arise with old age and previous evidence, mainly from animal models, suggests that the stem/progenitor cell pool decreases steadily with age. Studies with human cells have been generally hampered to date by poor sample availability.

Circumferential approach to contouring of the trunk.

Background: Body contouring usually involves the lower and upper abdomen, flanks, hips, and back. Several techniques are available with which to achieve suitable simultaneous correction of all these aesthetic units.

Objective: We review the techniques available for contouring of the trunk.
