Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...

Thioredoxins (Trxs) are small ubiquitous disulfide reductases that participate in dithiol-disulfide exchange reactions. In contrast to animals and prokaryotes that typically possess one or a few genes encoding Trxs, higher plants contain eight different Trx types: f, m, x, y, z, o, s, and h. Trx h with multiple forms is involved in different processes such as seed germination, cellular protecti...

background human preimplantation embryonic cells share many similarities with cancer cells such as ability to self-renew, unlimited proliferation and maintenance of the undifferentiated state. embryo-cancer sequence a (ecsa), also known as developmental pluripotency associated-2 (dppa2), is a cancer testis antigen (cta) with unclear biological function yet. objective: ctas are expressed normall...
