Learning objectives
The objective of this course is to provide scientific knowledge on in vitro embryo production, micromanipulation of gametes and embryos, molecular and cellular mechanisms driving embryo development. This knowledge will be applied to stem cell biology, both adult and tissue-specific, as well as embryo-derived. Further knowhow will cover the cutting age technologies such as cell conversion and reprogramming. Information about clinical applications of these techniques for the treatment of infertility and for the improvement of reproductive performances of domestic animals as well as the therapeutic use of stem cells will be critically evaluated. At the end students will be informed about sustainability issues indicating what strategies can be applied in the laboratory to limit environmental impact.
Expected learning outcomes
At the end of the course students will demonstrate their knowledge on the main requirements of an in vitro embryo production system as well as the meaning and the potential application of micromanipulation techniques applied to gametes and embryos. In addition, students will show a good understanding of the main molecular and cellular mechanisms driving embryo development, stem cell biology and cell reprogramming technologies. Student independent judgment will be demonstrated by the ability to critically read the specific literature. It is also expected that their communication skills using scientific terminology will be improved by this practice. In parallel, an environmentally aware laboratory attitude will be acquired.

Prerequisites for admission
It is advisable to know Histology, Anatomy, Physiology and Embryology.
Teaching methods
Attendance is strongly recommended for lectures and exercises.
Frontal lessons and laboratory exercises in small groups are given.
In the lectures, students are involved by stimulating their interest and encouraging them to participate by asking questions and asking to summarize parts already covered in the previous lessons.
In small group practical exercises, the student is guided to achieve autonomy in the manual skills necessary for the evaluation and treatment of gametes and cells in vitro.

Assessment methods and Criteria
The written exam consists of 2 open and 1 multiple choice questions for Reproductive Biotechnology (1 hour) and 30 multiple choice questions for Molecular Embryology and Regenerative Medicine (1 hour). Both parts are aimed at ascertaining the acquisition of knowledge during the course both during the theoretical lessons and during the practical exercises. A minimum of 18/30 must be achieved in each of the two parts of the exam.
