INTRODUCTION Diabetic foot ulcers (DFUs) are complex chronic wounds which have a major long-term impact on the morbidity, mortality and quality of patients. The objective of this study was to assess the efficacy and time sensitivity of human amnion/chorion membrane treatment in patients with chronic DFUs. METHODS The Cochrane Library, PubMed, Embase and Web of Science databases were systemati...

OBJECTIVE To determine the relationship of prostaglandin endoperoxide H synthase (PGHS) expression in the gestational tissues and fetal fibronectin in cervico-vaginal fluids before the onset of labour at term. DESIGN Cross-sectional, observational study. SAMPLES Amnion, chorion laeve and decidua were collected from 24 term pregnant women following elective caesarean section. Samples of cerv...

objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...

BACKGROUND AIMS Emerging evidence suggests human placental membrane is a valuable source of mesenchymal stromal cells (MSC). Amnion and chorion are tissues of early embryologic origin that may entail progenitor potential. These tissues are abundantly available and ethically unobjectionable and, because they are discarded post-partum, they can be widely used for extensive research and eventually...

Group B streptococci (GBS) have been cultured from the chorioamnionic membrane of pregnant women, usually in association with chorioamnionitis and premature labor (K. A. Boggess, D. H. Watts, S. L. Hillier, M. A. Krohn, T. J. Benedetti, and D. A. Eschenbach, Obstet. Gynecol. 87:779-784, 1996). Colonization and infection of placental membranes can be a prelude to neonatal GBS infections even in ...

Freshly isolated virulent and nonvirulent strains of Streptococcus agalactiae type III were used to study differences in coccal adherence to synchronously dividing, subconfluent human embryonic amnion and fetal lung monolayers in vitro. The adherence frequency by virulent isolates of mid-logarithmically growing cocci to amnion cells varied markedly with host cell age, being highest shortly afte...

The aim of the study was to examine the stimulatory effect of the inflammatory agent lipopolysaccharide (LPS) on the capacity of human term placenta to secrete interleukin (IL)-15 and IL-18. Isolated placental cotyledons from normal human term deliveries were dually perfused for ten hours with perfusion medium alone (n=5) or with perfusion medium containing LPS (1 microg/kg perfused placental t...

BACKGROUND We previously found in a murine hematopoietic system that hematopoietic stem cells show high differentiation and proliferation capacity on bone marrow-derived mesenchymal stem cells/stromal cells (microenvironment) with "self" major histocompatibility complex (MHC). DESIGN AND METHODS We examined whether amnion-derived adherent cells have the characteristics of mesenchymal stem cel...

Background: Burns are among the most common traumas in developing countries, which consume large amounts of medical resources. It is important to find an appropriate material for dressing of burn wounds that improves healing and is readily available, easily applicable, and economical. Methods: In a single-blind randomized controlled clinical trial from March to October 2006, 211 patients with l...
