Biotechnologies:experimental Models in Research

Unit 1: Cell culture
Design and equipment for a cell culture laboratory
Cell Culture - basic principles
- Main types of cell culture: primary cultures and cell lines
- The cell environment: sterile environment, pH, temperature and supply of nutrients for growth
- Basic techniques for cell culture: suspension culture, monolayer culture, 3D culture
- Advanced technique for cell culture: insert, scaffold and mammosphere
- Quality control
- Protocols for cell quantification and viability
Cell culture protocols and application to the field of animal nutrition
- Cell culture protocols for research: differentiation, tissue remodelling and nutrigenomic
- Epithelial cell barrier: trans epithelia transfer of nutrients, feed bioactive compound activity
- Cell culture for evaluation of feed functional and health claims
Journal club
Critically evaluation of recent articles in scientific literature (work group)
Exercises:
- The "Do's and Don'ts" of cell culture: aseptic technique and good cell culture practice
- Preparation and storage of culture media
- Cryopreservation and storage of cell culture
- Cytotoxicity and viability assay
- Culture of cell lines
- Cell-based assays for in vitro testing of functional properties of feed bioactive compounds and additives: probiotic adhesion tests
