Human embryos cultured in vitro to 14 days

We know a great deal about the development of the mammalian embryo until the time that the blastocyst implants into the uterus. With model organisms such as the mouse, we have also developed a considerable understanding of development immediately around gastrulation as embryos can be recovered at this stage for short-term in vitro culture. However, the intervening period of development remained...

Human chorionic gonadotropin secreted by preimplantation embryos cultured in vitro.

Human oocytes were collected by laparoscopy and fertilized and cultured in vitro. Human chorionic gonadotropin was detected in the medium surrounding two embryos cultured for more than 7 days after fertilization.

Behaviour of human embryos in vitro in the first 14 days: blastocyst transfer and embryonic stem cell production.

Improvement of Fertilization Rates of In Vitro Cultured Human Embryos by Exposure to Sound Vibrations

Exposure of in vitro cultured human embryos to microvibrations can improve embryo development, but music as a source of mechanical vibrations has not yet been explored. To determine the effect of the exposure to music during in vitro culture, 967 oocytes (114 patients) were analyzed. Before insemination, oocytes from each patient were randomly assigned to two groups: embryo culture exposed to m...

The effect of chloroacetophenone on chick embryos cultured in vitro.

INTRODUCTION BRACHET'S (1950) strong emphasis on the role of—SH-containing proteins in the process of induction has stimulated a study of the interference in the normal process of morphogenesis of chick embryos by chloroacetophenone, which has been described by Beatty (1951) as a specific and irreversible —SH inhibitor. He studied the effect of chloroacetophenone on the development of embryos o...
