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...
purpose: to evaluate the use of amniotic membrane transplantation (amt) for management of congenital distichiasis. methods: this interventional case series was performed on 16 eyelids of 5 patients with congenital distichiasis treated with posterior lamella resection and amt. results: all patients were men aged 2 to 42 years. mean follow up was 17 months (6-29 months). post-operative symptoms o...
Background & Aims: Human amniotic membrane has some specific properties making it an appropriate biomaterial for using in vascular tissue engineering. In this study, amniotic membrane was preserved with different methods. Effects of preservation on amniotic extracellular matrix and adhesion of cultured endothelial cells to membrane were compared with fresh samples of amniotic membrane. Mate...
purpose: to describe a novel surgical technique for in vivo limbal stem cell cultivation for reconstruction of corneal epithelium in total limbal stem cell deficiency (lscd). methods: patients suffering from chronic total unilateral lscd due to a chemical injury were sequentially included. one small limbal block (2x1 mm) harvested from contralateral healthy eye sutured over the amniotic membran...
Background and Objective: It has recently been shown that the application of amniotic membrane conditioned medium is effective in cancer treatment. In this study, the effect of amniotic stem cells conditioned medium on the activity of Hsp90 and Cdk4 expression, were investigated in cancer cells. Materials and Methods: Two cancer cell lines HeLa and MDA-MB-231 were treated with the supernatan...
Background & Aims: Amniotic membrane persists for a long time after ocular transplantation (as corneal substitute) and can affect light transmission (transparency). The aim of this study was to evaluate the transparency of amniotic membrane after freeze-drying (lyophilization) and to compare the results with transparency of rabbit cornea. Methods: Transparency of rabbits’ corneas and fresh and ...
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 ...
purpose: to evaluate the effect of amniotic membrane transplantation in trabeculectomy. methods: the study was conducted on 25 eyes of 25 patients with advanced and medically uncontrolled glaucoma. all patients underwent trabeculectomy with a fornix based conjunctival flap, amniotic membrane was then placed under the scleral flap and fixed using 10-0 nylon suture. amniotic membrane was retrieve...
Background and Objective: Though amniotic membrane has recently been introduced as a natural tissue with anti-cancer properties, there are inadequate studies about involved mechanisms. In this study, the effect of amniotic membrane culture supernatant on viability of cancer cells via applying different doses was evaluated. Apoptosis as a possible mechanism of inducing cancer cell death by amnio...
