background: radiotherapy is one of the most important factors which results in negative effects on wound healing and increases anastomosis leakage. diverting loop ileostomy has been usually performed after colorectal anastomosis in cases of colorectal cancer with a history of neoadjuvant radiotherapy to decrease the chance of leakage. considering the side effects of diverting loop ileostomy, th...

background mesenchymal stem cells (mscs) are ideal candidates for treatment of diseases. amniotic membranes are an inexpensive source of mscs (am-msc) without any donor site morbidity in cell therapy. adipose tissue derived stem cells (ascs) are also suitable cells for cell therapy. there is discrepancy in cd271 expression among mscs from different sources. in this study, the characteristics of...

background and aim: the aim of the present study was to compare coronally advanced flap (caf) with amniotic membrane to caf with connective tissue graft (ctg) in the treatment of miller’s class iⅈ gingival recessions. materials and methods: 11 systemically healthy patients, with 30 miller’s class і and іі gingival recessions ≥3 mm, were selected and randomly divided into two equal groups. gi...

purpose: to evaluate the properties of cultured limbal stem cells for corneal surface reconstruction. methods: specimens of limbal explants were prepared from the eye bank of i.r. iran. the explants were cultured and expanded on acellular amniotic membrane for 21 days. the cultured cells were evaluated for expression of connexin 43 and keratinine k3 by immunocytochemistry and expression of k12 ...
