Acute rejection of white adipose tissue allograft.

White adipose tissue (WAT) transplantation, although widely used in humans, has been done for cosmetic and reconstructive purposes only. Accumulating evidence indicates, however, that WAT is an important endocrine organ and, therefore, WAT transplantation may become valuable as a replacement therapy for a number of hereditary human diseases. Because the most readily available source for such transplantations would be allogeneic tissue, the mechanisms involved in the rejection of WAT allograft should be explored.
