Vocal fold scars and sulcus cause severe vocal problems, but no optimal treatment has been established. In cases, in which the entire lamina propria is occupied by fibrosis vibratory function completely lost, more powerful regeneration materials should be used, or mucosa totally replaced. Amniotic membrane a scaffold material that rich stem cells growth factors high regenerative effect. It can ...

AIM/PURPOSE OF THE STUDY To develop a one-week storage method, without serum and xenobiotics, that would maintain cell viability, morphology, and phenotype of cultured human limbal epithelial sheets. MATERIALS AND METHODS Human limbal explants were cultured on intact human amniotic membranes for two weeks. The sheets were stored in a hermetically sealed container at 23°C in either a serum-fre...

Injection of amniotic fluid stem cells ameliorates the acute phase of acute tubular necrosis in animals by promoting proliferation of injured tubular cells and decreasing apoptosis, but whether these stem cells could be of benefit in CKD is unknown. Here, we used a mouse model of Alport syndrome, Col4a5(-/-) mice, to determine whether amniotic fluid stem cells could modify the course of progres...

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...

Little is known about the origin of albumin in amniotic fluid. A fetal origin is questionable, because of the low concentration of protein in fetal urine and lung fluid. A maternal origin of proteins in amniotic fluid was already proposed in the 1970s. This review focuses on the possible sources of albumin in amniotic fluid and on the pathways for albumin to enter and leave the amniotic fluid i...

Intraperitoneal amniotic fluid leak is a known complication of fetoscopic procedures that usually resolves spontaneously with expectant management. Intraperitoneal amniotic fluid leak may persist after fetoscopic procedures due to a myometrial window as well as to persistent chorioamniotic membrane disruption, which may be amenable to surgical repair.

The aim of this study was to construct an artificial fetal membrane (FM) by combination of human amniotic epithelial stem cells (hAESCs) and a mechanically enhanced collagen scaffold containing encapsulated human amniotic stromal fibroblasts (hASFs). Such a tissue-engineered FM may have the potential to plug structural defects in the amniotic sac after antenatal interventions, or to prevent pre...

BACKGROUND Different methods for dressing of donor site of skin graft in burn patients have similarly pain, limitation of mobility of donor site and local complications such as infection and scar. Amniotic membrane has used for improvement of healing in some wounds. Accordingly in this study amnion was used as biologic dressing for donor site of skin graft to evaluate it’s efficacy in improveme...

Amniotic membrane was obtained from 36 mothers seronegative for hepatitis B surface antigen and syphilis, undergoing caesarean section. Membrane was separated from placenta and was washed first with saline and then saline solution containing penicillin. The processed membrane was found to be sterile and useable for up to one week. Of 36 placentas obtained, 33 were utilized in 22 patients, with ...
