The aim of this subject is to familiarize students with the structure of specialized cells in the human body, taking into account the functions of individual organelles and their importance for the cell and the whole organism. Particular emphasis is placed on integrating knowledge of basic disciplines with clinical sciences and linking issues of cell biology with practical problems of medicine, including understanding cellular, subcellular and molecular diagnostic and therapeutic strategies, mechanisms of drug action and regenerative capacities of the body.
Wymagania wstępne
The student should have a basic knowledge of mammalian cell structure.

Methods of cell preparation for testing: cell isolation, homogenization, cell culture.
Molecular studies of homogenates; isolation of nucleic acids and proteins. In situ molecular studies: nucleic acid hybridization and protein immunocytochemistry. Applications of nucleic probes, poly- and monoclonal antibodies, and polyclonal probes.
Specialized methods of DNA and RNA study commonly used in medical diagnostics and science: sequencing, microarrays, PCR and its variants (RT- PCR).
Specialized methods of protein testing: quantitative protein assays: RIA and ELISA; genetic labeling and flow cytometry.
Microscopic studies: light and electron microscopes and their types.
Metody kształcenia
Seminars conducted using a computer-microscope network, synchronized with microscopic images, diagrams and examples to be solved - the student solves the presented tasks independently, in interaction with the teacher. Introductory topics are presented in the form of multimedia presentations and provide a theoretical introduction to selected issues, with the students then independently analyzing and solving problem tasks.

Verification of the established learning outcomes is carried out through a range of methods of student assessment:
Points obtained for each seminar and preparation for class. During each course class, the student can obtain from 0 to 2 points, which are awarded based on:
theoretical preparation for class
discussion based on solving problem tasks, independent solving of engagement-promoting tasks linking selected issues of cytophysiology with known diseases
observation of the student’s analysis and solving of problem tasks
2. The score of the credit test consisting of 60 single-choice questions, for which the student can obtain 60 points.
3. The maximum number of points that a student can obtain is 70.
Credit for the course is based on the achievement of at least 60% of the possible points from the seminars and 60% from the credit test. The final grade is calculated based on the sum of the points from the seminar and the credit test. The points obtained are converted into grades according to the following scale:
90-100% = 5.0
83-89% = 4.5
74-82% = 4.0
67-73% = 3.5
60-66% = 3.0
0-59% = 2.0
Students with excused absences should consult with the teacher and make up for them within up to 14 days, but no later than the day of the credit test.
For each unexcused absence, 6 points are deducted from the total score, and verification of the material must be arranged with the teacher. In the case of 2 unexcused absences, the coordinator shall notify the Dean of the fact, who shall decide whether to continue to credit or withdraw the student from the compulsory classes in the course.
Regulations on credit conditions correspond to the conditions for direct credit, subject to the possibility of changes in the event of the need to switch to remote crediting in the regulatory time, before the start of the examination session.
