• Developmental Potential of Bovine Androgenetic and Parthenogenetic Embryos: A Comparative Study1 .
• In this study, we compared the developmental capacity of bovine haploid and diploid androgenetic and parthenogenetic embryos obtained by different methods. Androgenetic embryos were produced by piezo-intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF) of enucleated oocytes with or without subsequent pronuclear transfer from one haploid zygote to another. Parthenogenetic embryos were obtained by activation of matured oocytes by ionomycin combined with cycloheximide or 6-dimethylaminopurine (DMAP) treatment. Only few cleaved androgenetic haploid embryos were able to compact (2. ... By contrast, development to blastocyst of diploid androgenotes, cloned androgenetic embryos, and parthenogenotes (31%, 39%, and 43%, respectively) was similar to IVF control embryos (35%). Cell number on Day 7 was higher for IVF blastocysts and decreased in consecutive order in diploid androgenotes, diploid parthenogenotes, and haploid uniparental embryos. Following transfer of diploid androgenetic embryos, a pregnancy was established and maintained up to Day 28. ...

• The establishment of in vitro fertilization and culture systems for mammalian embryos has facilitated the application of embryo technologies in research, industry, and clinical settings. ... Based on studies in cattle, sheep, and mice, it has become apparent that embryos produced using these systems can differ in morphology and developmental potential compared with embryos produced in vivo. Referred to as "large offspring syndrome," these abnormalities in the development of fetuses, placentas, and offspring are particularly evident following transfer of cloned embryos, but they also occur in pregnancies from embryos produced using in vitro culture alone. ...

• A Force Balance Model of Early Spindle Pole Separation in Drosophila Embryos .
• To address this issue we have modeled the separation of spindle poles as a function of time during the early stages of spindle morphogenesis in Drosophila embryos. ... As a result, we obtained graphs of the time course of spindle pole separation during interphase and prophase that display a reasonable fit to the experimental data for wild-type and motor-inhibited embryos. ...

• Keywords: Advance directives; autonomy; embryo disposition; frozen embryos; Ulysses contracts.
• These rights are expressed in the general acceptance of the gamete providers or intentional parents as the primary decision makers about embryos resulting from infertility treatment. In most centres around the world, it became standard practice to ask patients to sign a consent form in which they indicate what should be done with the frozen supernumerary embryos when these are no longer needed for their own reproduction. This practice partly developed because of the remarkable fact that a considerable number of the embryos are abandoned by the gamete providers or intentional parents. ...
•    CONTRACTS CONTAINING ADVANCE DIRECTIVES FOR THE DISPOSITION OF EMBRYOS .
• The persons for whose reproduction the embryos were created give a current informed consent to freeze their supernumerary embryos and simultaneously issue orders as to what should be done with the embryos some time in the future. They have the right to order the disposition of their embryos if the chosen option is among the list of options accepted by the clinic. ... 1 The term is used here in the general meaning of an authoritative instruction given by a competent couple regarding the type of treatment (in this case the disposition of their embryos) they want to receive in case they become incompetent in the future. ...
• Originally, the request for advance directives for the disposition of embryos was motivated by the wish to avoid messy situations when some accident happened. ... must state what is to be done with the gametes or embryos if he or she dies, or becomes incapable of varying or revoking his or her consent". ... Instructions to dispose of the embryos were requested for almost every imaginable future situation. ... More than 30% of the Assisted Reproductive Technology (ART) programmes in the United States address the disposition of embryos in this situation rather than trying to contact the patients in the event of dissolution. 5 The informed consent forms are used by the clinics to facilitate the management of the "stock" of embryos. It is fully acceptable that clinics obtain prior agreements for the disposition of the embryos. Also, they rightly wish to have a clear legal authority for handling the embryos, in the absence or unavailability of the patients. ... Although the early court cases (Davis v Davis and Kass v Kass8,9) supported the view that a prior written consent about embryo disposition should be enforced, a later case (AZ v BZ10) upheld the right not to procreate of one partner although there was an agreement signed by both partners to release the embryos to one spouse. ...
