Knowledge

The course is composed by two separate modules: “Principles of cellular biology” (3 CFU) and “Tissue Engineering” (9 CFU). The student who completes the course successfully will be able to demonstrate a basic knowledge of cellular biology. Moreover, student will have an understanding of advanced tissue engineering methods that apply physicochemical manipulation of materials in order to direct cell function and tissue regeneration. Techniques and equipment of bench research, related to cell culture, scaffold fabrication methods and scaffold functionalization strategies, will be illustrated. A complete overview of the current state of the art in the engineering of human tissues will be provided. Emphasis will be also placed on developing the written and oral communication skills required to a scientist.

Assessment criteria of knowledge

“Principles of cellular biology” module: final written test.

For the “Tissue engineering” module, the exam will comprise:

- a student assignment, consisting of an oral presentation to the class with slides about an assigned topic;

- a final written test, in which the student should demonstrate her/his knowledge of the course topics, by answering open questions. The student should answer each question in a broad and comprehensive way, using the appropriate terminology.

Skills

With regard to the “Tissue Engineering” module, at the end of the course the student will be able:

- To know the key elements of tissue engineering: cells, scaffolds and signals;

- To know the basic techniques and equipment for in vitro cell cultivation;

- To understand the basic principles of the different tissue engineering approaches;

- To understand the existing strategies to design and fabricate scaffolds;

- To understand the methods to develop bioactive and biomimetic scaffolds;

- To know the current state of the art in the engineering of different human tissues.

Assessment criteria of skills

“Tissue engineering” module: oral presentation of the assignment: 50%, final written test: 50%

The final grading of the “Principles of cellular biology and Tissue Engineering” exam will be the weighted average of the assessments obtained in the different modules.

 

Behaviors

Students can acquire and develop sensitivity to both biological and engineering issues of tissue regeneration.

 

Assessment criteria of behaviors

For both modules, the tools used to ascertain the expected behavior acquisition are:

  • Interaction with the teacher through receptions;
  • Questions addressed to students during the front lessons, to verify the acquisition and consolidation of certain concepts.
Prerequisites

A basic knowledge of materials science, chemistry and biology is suggested.

Teaching methods

Delivery: face to face

Learning activities: attending lecturers; participation in seminars
