Experience in Using Fetal Membranes: The Present and New Perspectives.

INTRODUCTION: The placenta is an accessible source of tissues for transplantation. Placental transplants have been used in wound treatment because of the basic function of the placenta and its nutritious properties and structure.

PATIENTS AND METHODS: The aim of this work is to present the clinical usage of fetal membranes, including human amnion, on the basis of the burn treatment center's experience. The clinical use of amnion and different types of placental transplants are described. The initial results of research work within the MEDPIG project are presented regarding the application of placenta from transgenic pigs as a source of tissues for transplantation.

RESULTS: From August 2011 to March 2017, 252,592 cm2 of biostatic human amnion transplants were prepared in our tissue bank. During this period they were transplanted to 528 patients, including 10 patients with Lyell syndrome. Initial studies were conducted in which placentas were collected from 5 transgenic pigs and 27,426 cm2 of amniotic grafts were prepared from them.

DISCUSSION: The authors' own experience as well as the literature confirm the extraordinary efficiency of transplants prepared from placental tissues, especially from the amniotic membrane.

CONCLUSIONS: The clinical effects confirm the effectiveness of using human amnion in wound treatment. Amniotic transplant is a new treatment standard in toxic epidermal necrolysis TEN (Lyell's syndrome), which has found confirmation in very good clinical outcomes. The collected placentas from transgenic animals enabled the preparation of significantly more grafts than in the case of human material, which is a great advantage of this source of placenta over human tissues.
