The high attrition rate of in vitro human embryo culture presents a major obstacle in the treatment of clinical infertility by in vitro fertilization (IVF). Physical and genetic requirements are not well understood for human or mouse preimplantation embryo development. Group culture is an established requirement for optimal embryo development in the mouse model. However, conventional microdrop ...
this study was designed to examine the effects of retinoic acid adding to cumulus and/or fibroblast cellsmonolayer on the development of mouse early embryos. one-cell mouse embryos were obtained from nmrimice after superovulation by an intraperitoneal injection of 5 iu equine chorionic gonadotrophin (ecg)followed 48 hrs later by 5 iu human chorionic gonadotrophin (hcg). mouse embryonic fibrobla...
In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...
