BALB/c mouse embryo cells maintained in tissue culture on a schedule of rapid transfer at high cell density develop into tumorigenic lines that have lost contact inhibition of cell division. After several months in culture, certain of these lines begin to release mouse leukemia virus. This virus has properties indistinguishable from those of virus found in adult BALB/c mice. The evidence presen...

Colchicine has been used to induce chromosome doubling in plant species. Diploid cotton species have inherited desirable genes that are resistant to biotic and abiotic stresses and also possesses useful fiber quality traits, such as higher fiber length and strength. To transfer these desirable traits to the most extensively cultivated tetraploid cotton species through hybridization, it is a pre...

Embryo culture can serve as a strong diagnostic tool, yielding useful information regarding the implantation potential of the human embryo. The information thus gained is useful for quality control of the embryology laboratory, success rates of the IVF/intracytoplasmic sperm injection (ICSI) programme, and counselling of the couple following failed cycles. Zygotes can be scored and zygote quali...

introduction: it is now generally accepted that vero cells provide beneficial effects on improving embryo quality in many animal species. the aim of this research was to determine the effect of vero cell co-culture on the development of vitrified 8-cell mouse embryos. material and methods: eight- cell mouse embryos were provided from superovulated female nmri mice and divided into treatment cas...

BACKGROUND Advances in embryo culture technology and cryopreservation have led to a shift in in vitro fertilization (IVF) from early fresh or frozen-thawed cleavage embryo transfer to fresh or frozen-thawed blastocyst stage transfer. OBJECTIVE To compare the clinical outcomes of fresh embryo transfers and frozen-thawed embryo transfers. MATERIALS AND METHODS In this retrospective case contr...

BACKGROUND High concentration of glucose in culture medium affects the developmental process and the quality of the pre-implantation embryo. This study examined the effects of Zuogui Wan (ZGW) supplementation on early embryo development cultured in high-glucose medium. METHODS Embryos were cultured in high-glucose medium with or without ZGW supplementation. Developmental rate and competence w...
