Natural Selection and Adaptive Evolution In natural settings, adaptive evolution takes place by natural selection, a process in which differences in traits lead to differences in survival and reproductive success between individuals. This happens because individuals with certain phenotypes have a higher probability of survival and/or produce more surviving offspring than individuals with other phenotypes. A classic example of this was demonstrated by Rosemary and Peter Grant studying the...

Observing Artificial Selection in Plants ExpandTo begin the experiment, collect five two-week old grown plants from the generation one population that appear healthy. Note: Plants should appear green, not wilted, and not have damaged leaves. Experimental Hypothesis: The experimental hypothesis for this lab might be that the number of lead trichomes varies naturally, but the average number will increase over generations if only plants with the highest number of trichomes are interbred or...

2025
This video describes an antegrade perfusion technique of an isolated mouse heart during which a perfusate is injected through the left ventricle, and eventually, it perfuses the entire myocardium. This method can be used to isolate cardiomyocytes from murine models and generate decellularized hearts for further downstream applications.

FAQs
An artificial perfusate must support a continuous exchange process: it delivers oxygen and nutrients to cells while carrying metabolic waste away from vascular or tissue compartments. This circulation helps sustain physiological activity outside the body. The balance between supply and removal is therefore central to interpreting whether an organ or biological model remains functionally responsive during an experiment.
Suitable pH and osmotic balance help create conditions that meet cellular requirements during circulation. If these properties are not appropriately formulated, the fluid may not adequately support the tissue environment being studied. Maintaining both factors allows researchers to examine organ or tissue behavior under controlled conditions rather than allowing uncontrolled fluid properties to dominate the experimental outcome.
Circulation through vascular or tissue compartments determines how the perfusate contacts the biological material and delivers its supportive components. This arrangement enables oxygen and nutrients to reach relevant regions while metabolic waste moves away. As a result, researchers can investigate responses within an organ or tissue model while keeping perfusion separate from the complex influences of whole-body physiology.
By replacing whole-body circulation with a controlled perfusion system, investigators can examine an organ's responses without relying on the coordinated physiology of an intact organism. This separation makes it possible to test interventions and study tissue function under defined conditions. The approach is especially useful when researchers need to distinguish organ-specific effects from broader systemic influences.
A typical workflow begins by formulating the fluid to support cellular oxygen and nutrient needs while maintaining suitable pH and osmotic balance. Researchers then circulate it through the isolated organ, tissue, or biological model so that waste can be carried away. The resulting physiological activity and responses provide the basis for studying function under controlled ex vivo conditions.
Artificial perfusate is used when investigators need to maintain an organ outside the body or evaluate conditions relevant to transplantation. Its circulation supports organ activity during ex vivo preservation and allows researchers to examine how the organ responds to interventions. These studies can help refine approaches for maintaining tissues and improving transplantation-related strategies.
In tissue engineering and regenerative medicine, artificial perfusate provides a controlled way to support biological models while researchers study tissue function and responses. Circulation can deliver oxygen and nutrients through tissue compartments and remove metabolic waste. This makes perfusion relevant for evaluating engineered tissues and for refining strategies intended to maintain or restore biological activity.
