Objectives and Contextualisation
Cell Culture course is taught in the 2nd semester of the 3rd year of the Biotechnology degree in the Faculty of Biosciences. This is a subject with a certain degree of expertise that is intended to acquire a basic knowledge to work in a cell culture laboratory. It is therefore a subject with an important practical component.
Course objectives:
1) Know the basic equipment of a cell culture laboratory.
2) Know the most used types of cultures
3) Know the basic methodologies used in cell cultures.
Competences
- Apply general laboratory security and operational standards and specific regulations for the manipulation of different biological systems.
- Apply the principal techniques for the use of biological systems: recombinant DNA and cloning, cell cultures, manipulation of viruses, bacteria and animal and plant cells, immunological techniques, microscopy techniques, recombinant proteins and methods of separation and characterisation of biomolecules.
- Describe the molecular, cellular and physiological bases of the organisation, functioning and integration of living organisms in the framework of their application to biotechnological processes.
- Design and implement a complete protocol for obtaining and purifying a biotechnological product.
- Interpret experimental results and identify consistent and inconsistent elements.
- Make decisions.
- Think in an integrated manner and approach problems from different perspectives.
- Work individually and in teams

PRACTICAL SESSIONS PROGRAM: Broadly speaking, the practices consist of the manipulation of animal eukaryotic cell cultures. The 5 laboratory sessions are designed so that the student complements his theoretical training with basic techniques and the tools of a cell culture laboratory. In the practical sessions you will work on:
- Subculture of animal cell lines in a biological safety cabinet.
- Establishment of a cell growth curve.
- Immunofluorescent detection of microtubules and observation in the epifluorescence microscope.
- Freezing and thawing of cells: recovery and survival rate.
- Induction and analysis of apoptosis.
- Alteration of the cell cycle by different drugs.
- Discussion of results.
Methodology
Given its theoretical-practical aspect, the Cell Cultures subject consists of both theoretical lectures -10 hours- and practical classes in the laboratory -16 hours- (see table of training activities).
- Theoretical classes are usually scheduled for the first three weeks of the second semester. The master classes will be carried out using audiovisual material prepared by the teaching staff, material that the students will have at their disposal in * pdf format in the Moodle of the subject before the start of the sessions. It is recommended that students consult the audiovisual material and the books recommended in the Bibliography section of the teaching guide or class slides to consolidate the contents explained in class.
- The practical classes of the subject are designed so that students learn to use laboratory instruments and complete their theoretical training. These practices are not associated with the Integrated Laboratory VI subject, since, as mentioned, the cell culture subject is theoretical-practical.
Practical classes will be scheduled in 4 turns of students and each one of the turns will consist of 5 sessions with a total of about 16 hours distributed from Monday to Friday. For each one of the groups, a presentation session of the practices will be programmed, which will be of mandatory attendance the week before the start of the practices. The list of students in each turn will be published in the Moodle of the subject. Group modifications are accepted but require exchange of students among groups.
The practice script will be available in * pdf format in Moodle. For the proper functioning and understanding of the practices, students must read the practice scriptcorresponding to each session and watch the recommended videos. Each day an exercise (via Moodle) or a questionnaire (in the classroom) must be handed at the beginning of each practical session on issues related to the day's experiments. These activities will be evaluated and will have a weight in the final grade of the subject. Delays in arriving at the practical sessions will lead to not being able to complete the questionnaires.
The students will work in groups of 2 people, and on a daily basis they will have to fill out a results sheet/form with the obtained data. The results obtained by the couple will be evaluated and will have a weight in the final grade of the subject. On the last day of practices, the results obtained in each of the practices will be assessed and discussed.
- The tutorials will be carried out in a personalized way in the teacher's office (door C2/050 and hours to be agreed). The tutorials should be used to clarify concepts, settle the knowledge acquired and facilitate the study by the students, among others.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
The evaluation will consist of activities corresponding to the theoretical part of the subject (65% of the overall grade) and to the practical part (35% of the overall grade). Thus, the evaluation will consider both the scientific knowledge acquired by each of the students individually and the results obtained and worked on in groups during the practices.
Specifically, there will be:
Theory: it will consist of 2 differentiated parts that will evaluate the knowledge acquired on different concepts taught in theory classes and a practical case to be solved where different experiments or techniques will have to be determined to be applied to reach the expected results.
1) Theory exam (55 % of the mark).
2) Practical case to solve (10 % of the note).
Practices
3) Questionnaires and laboratory exercises (10 % of the grade).
4) Results of practices (10 % of the note).
5) Exam of practices and discussion of results (15 % of the grade).
Students who do not hand in the questionnaires and/or results of the practices will have a zero for this part of the course. Students who follow the single assessment will take the practice exam on the same day as the theory synthesis exam.
It is noteworthy that the attendance at practical sessions is mandatory. The absence of one of the practical sessions implies a penalty of 25% of the mark in this section. Students will obtain the "Non-Appraising" qualification when their absence in the practical module exceeds 20% of the programmed sessions (2 or more sessions).
General considerations
To pass the course, a minimum grade of 4,0 out of 10 is required in the multiple choice exam of the theoretical assessment and that the weighted average of all 5 grades is equal to or greater than 5,0 points out of 10.
Recovery Activities
Students who initially do not pass the course may take the retake process. However, to participate in the recovery, students must have been previously evaluated in a set of activities whose weight is equivalent to a minimum of two thirds of the total grade for the subject (67%).
In summary, the recovery will consist of a multiple choice exam, which will evaluate the achievement of the training objectives corresponding to the written-theory tests. All those activities corresponding to the practices are excluded from the recovery process.
The different assumptions to appear for recovery may be:
- That the grade on the theory exam has been less than 4,0 (out of 10).
- That the weighted average of the written + practical tests is less than 5,0 points (out of 10).
Only the tests corresponding to the theoretical part of the subject may be recovered: multiple choice exam (1) and/or case study (2). Each of them will have a weight equivalent to that of the initial tests. Attention, the practical part of the subject is excluded from the recovery: sections "Questionnaires and laboratory exercises (3)", "Laboratory results (4)" and "Practice exam and discussion of results (5)".
Finally, those students who -having passed the course- want to present themselves to raise their grade, may do so as long as they notify the teaching staff one week in advance. It should be noted that, in this context, students waive the grade obtained in the previous written tests.
