“Sporadic reports published during the previous decade have documented pregnancies achieved with

transfer of zona-free human embryos. Although the overall efficiency seems to be good and some authors have suggested systematic application for special infertility problems, there have been only a few attempts to compare the benefits of zona-free embryo culture and transfer SNX-5422 purchase with the traditional approach using zona-intact embryos. So far, the majority of instances in which zona-free culture has been applied have occurred accidentally. This review summarizes the known functions of the zona pellucida, analyses natural and artificial situations where its function is compromised, including zona hardening and difficult hatching that seem to be related to in-vitro embryo culture, and discusses possible methods and timing for artificial zona removal. With the availability of in-vitro systems capable of replacing important functions of the zona pellucida, routine use of zona-free culture for the whole in-vitro period, after or even before fertilization, is a realistic possibility with potential additional benefits. Based on the increasing amount of animal studies, a systematic comparison Selleck PARP inhibitor is suggested that may

eventually diminish the handicaps of the in-vitro situation and lead to simplification of manipulations LY2835219 as well as higher success rates after embryo transfer. (C) 2010, Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.”

“Embryonic stem cells (ESC) are pluripotent cells and have the ability to self-renew in vitro and to differentiate into cells representing all three germ layers. They provide enormous opportunities for basic research, regenerative medicine as well as drug discovery. The mechanisms that govern ESC fate are not completely understood, so a better understanding and control of ESC self-renewal and differentiation are pivotal for therapeutic applications. In contrast to growth factors and genetic manipulations, small molecules offer great advantages in modulating ESC fate. For instance, they could be conveniently identified through high-throughput screening, work across multiple signalling pathways and affect epigenetic modifications as well. This review focuses on the recent progress in the use of small molecules to regulate ESC self-renewal, differentiation and somatic cell reprogramming. (C) 2010, Reproductive Healthcare Ltd.
