Teaching description

No formal prerequisites or propedeuticity are required. However, a solid knowledge of cell biology, molecular biology and genetics it is strongly recommended in order to be able to follow the course fully understanding the different topics

Synthetic program:

Genetic manipulation of eukaryotic cells. Methods for expressing or silencing wt and mutant genes in cultured animal cells. Cellular and molecular biotechnologies to identify protein-protein interactions: the two-hybrid system and its variants, the phage display. Biology of stem cells: embryonic, foetal and adult. Applications of stem cells. Induced pluripotent stem cells. Regenerative medicine. Gene therapy: vectors, methodologies and scopes. Cloning and therapeutical cloning.

Program of pratical laboratory classes:

Transfection of mammalian cells. Use of GFP to monitor transfection efficiency. Transfection of GFP-tagged proteins to establish their intracellular localization in mammalian cells. Immunofluorescence analysis. Differentiation of cultured mammalian cells.

The course aims to provide knowledge and skills to work professionally with roles of responsibility in the areas of medical biotechnology which make use of eukaryotic cells (wt or genetically modified).

Learning outcomes

Knowledge to be attained:
• Up to date technologies for genetic manipulation of cultured eucaryotic cells for gene function and therapeutical applications.

• Cellular and molecular biotechnologies to study and unravel molecular interactions

• Biology of embryonic and adult stem cell biology  and of their therapeutical applications.

• Gene therapy approaches

Abilities to be attained:
• Gene expression in mammalian cells
• Gene silencing in mammalian cells
• Use of reporter genes to monitor transfection efficiency, protein intracellular localization and protein activity.

Formal lectures (8 cfu= 64 hours) making use of slides and hypertext links to specific Web sites and pratical laboratory classes (1 cfu = 10 hours). Outside these activities, the students are expected to read assigned papers from scientific literature.

The evaluation of the oral examination will be based on the level of the theoretical knowledge and practical abilities acquired through the description of topics and methodologies (70%), on the critical and problems solving abilities and (20%) and on communication skills (10%).
