在意大利的博洛尼亚,以佩特鲁奇教授为首的三个科学家最近试验人卵在体外人工受精成功。在四十二次试验中,有一次胚胎发育达二十九天,又一次则达五十九天。这一成就在科学界中引起了轰动。但梵蒂冈的报纸却认为这种实验是不慎的行为。博洛尼亚的大主教甚至拒绝承认作为天主教徒的佩特鲁奇教授。虽然条件是困难的,据就他仍然想试一试在人工条件下培养出一只兔子。为了进行人卵体外受精和发育,他们已经准备了四年。他们创造一种防止受胎细胞死亡的特殊仪器——“生物摇篮”,把两性生殖细胞和一定的营养物注入“摇篮”中后, In Bologna, Italy, three scientists, led by Professor Petrus, recently tested human eggs for artificial insemination in vitro. In forty-two trials, one embryo developed for twenty-nine days and the next one fifty-nine days. This achievement caused a sensation in the scientific community. Vatican newspapers, however, considered the experiment inadvertent. Archbishop of Bologna even refused to recognize Professor Petrusulu as a Catholic. Although the conditions are difficult, according to him still want to try to cultivate a rabbit under artificial conditions. They have been prepared for four years for human in vitro fertilization and development. They create a special instrument to prevent the death of fetal cells - “biological cradle”, the gender of germ cells and nutrients into the “cradle”
