“…There was one case of PPROM within 3 weeks of the procedure. However, the overall gestational age at delivery in their series was 28.4 weeks with a procedure-to-delivery interval of 6.5 (range, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] weeks. This gestational age at delivery was 3-4 weeks lower than in other published series.…”

“…Both rabbit and sheep have a large allantois that plays a major role in nutrition of the membranes. Finally, the animal membranes are vascular, a characteristic lacking in human membranes and that prevents healing 4 . Chang et al 15 published the only other human study of placement of a gelatin sponge to reduce the rate of iPPROM after fetoscopy.…”

“…This is often associated with a mean reduction of 2 weeks in the gestational age at birth 2 . iPPROM has been attributed to a persistent fetal membrane defect at the trocar entry site 3,4 . Investigators have explored intra-amniotic or extra-amniotic 5 instillation of platelets and/or maternal blood to treat iPPROM, and mixed results have been obtained.…”

“…This is typically referred to as iatrogenic PPROM or iPPROM, pointing to the circumscribed, surgical injury occurring to the membranes at the time of intervention. It has been shown that those trauma sites show little if no healing capacity (Gratacos et al, 2006). Because of the clinical relevance of its consequences, several groups have explored the possibility to treat or prevent iPPROM from happening by sealing the membrane defect.…”

A common characteristic of mammals is the development of extraembryonic supporting tissues and organs that are required for embryonic implantation, survival and development in utero. The amnion is the innermost extraembryonic membrane that eventually surrounds the fetus of amniotes, and contains the amniotic fluid. Next to its function in in utero development, the amnion has been shown to have an important potential for clinical applications. It is mainly used as a dressing to stimulate healing in skin and ocular wounds. Moreover, cells derived from the amniotic membrane and amniotic fluid have been reported to possess stem cell features, like pluripotent differentiation ability. Little is known about the early development of this membrane in humans. The mouse is a powerful genetic model organism that can be used to address the dynamics and the developmental origin of amnion and amnion-derived stem cells. Here, we discuss some fundamental differences in amnion development in the disc-shaped primate embryo and in the cup-shaped mouse embryo. We emphasize the consequences that this may have on the derivation of amniotic "stem" cells. After revision of the different isolation procedures of amniotic (fluid) derived "stem" cells from rodents, we reveal striking differences in the sources used to derive these cells across studies. The profound differences in the development of the extraembryonic membranes and cavities between primates and rodents may result in comparing cell types of different developmental origins, eventually leading to missinterpretations.

“…One of the contributing factors for iPPROM is the non-healing nature of the fetal membranes. The previously proposed mechanism for non-rupture of the membranes after fetoscopy was sliding of the amnion over the chorion once the operative cannula is removed, thereby sealing the site of defect mechanically 4 . However, the findings in our case undermine this theory and support membrane-decidual adherence as the major reason for absence of amniotic fluid leakage at the fetoscopic puncture site.…”
