How to obtain physiologically relevant cardiovascular data with students using chick embryo ventricular...

Area of Science:

• Physiology
• Pharmacology
• Cardiovascular Research

Background:

• Traditional animal models for teaching cardiac physiology face ethical concerns.
• There is a need for accessible, ethical alternatives in scientific education.
• Chick embryo cardiomyocytes offer a viable model for studying heart cell function.

Purpose of the Study:

• To present an ethical and accessible chick embryo ventricular cardiomyocyte model for physiology and pharmacology education.
• To enable students to perform hands-on experiments on cardiac cell physiology and drug mechanisms.
• To provide an alternative to animal experimentation in cardiovascular research training.

Main Methods:

• Utilizing standard physiology teaching laboratories and basic cell culture equipment.
• Isolating and culturing spontaneously beating chick embryo ventricular cardiomyocytes.
• Conducting experiments to observe the effects of temperature, media changes, and pharmacological agents (e.g., isoproterenol, beta-3 agonists) on cardiomyocyte beating rates.

Main Results:

• Students can successfully culture and observe beating cardiomyocyte colonies.
• Demonstrated significant alterations in beating rates due to temperature and media changes.
• Obtained dose-dependent responses to beta-adrenoceptor agonists, illustrating classical log dose-response curves.

Conclusions:

• The chick embryo cardiomyocyte model provides an effective, ethical, and engaging platform for teaching fundamental cardiac physiology and pharmacology.
• This model enhances student understanding of physiological principles and drug actions.
• It serves as a valuable, humane alternative for training future scientists in cardiovascular research.
