previous studies have shown that morphine administration could inhibit neural tube development in rat embryos and produce behavioral defects in human and animals. in the present study, the effects of maternal morphine consumption on embryonic neural plate development in wistar rats were investigated. methods: twenty-four female wistar rats (250-300 g) were crossed with males. after pregnancy, t...

To find a suitable feeder layer is important for successful culture conditions of bovine embryonic stem cell-like cells. In this study, expression of pluripotency-related genes OCT4, SOX2 and NANOG in bovine embryonic stem cell-like cells on mouse embryonic fibroblast feeder layers at 1-5 passages were monitored in order to identify the possible reason that bovine embryonic stem cell-like cells...

Teratomas are tumors originated from mature or immature tissues. Teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). Herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. After physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...

This video demonstrates how to maintain the growth of human embryonic stem cells (hESCs) in feeder cell-free conditions and how to continuously passage hESCs in feeder cell-free conditions. Confirmation of hESC pluripotency grown in feeder cell-free conditions by immunofluorescence microscopy is also demonstrated.

Focal dermal hypoplasia or Goltz syndrome is a rare genodermatosis involving all three embryonic layers. Herein, the first case of this syndrome from Iran will be reported. The main clinical features were fat herniation, reticulate pigmentations, telangiectasia, and skeletal defects.

Recently new reports have proved the pluripotency of spermatogonial stem cells (SSCs) derived from male gonad. This pluripotent stem cells resembled Embryonic stem cells recognized as Embryonic Stem like cells (ES like cells). ES like cells forms sharp edge colonies that are immunopositive to pluripotency markers and have differentiation capacity to Ectodermal, Mesodermal and Endodermal layers....

due to the high economic value of ostrich and the farming industry to further promote increased productivity, knowledge in different fields of science, including detailed knowledge of tissue structures vital organs from this animal looks. ostrich’s eye is the cornea closest to the human eye because of the same anatomical features of the human cornea, corneal transplantation can be used ostrich....
