What types of tissues can be used for explants?
Explants can be isolated from various tissues, including ovium, liver, and lung.
Why is a native 3D environment important?
It allows for more accurate profiling of cellular interactions with their surrounding matrix.
What key measurements were taken during the study?
Metabolic activity was measured as an indirect assessment of cell viability.
How often should the culture medium be changed?
The culture medium should be changed every two to three days.
What is the significance of IGF-1 treatment?
IGF-1 was shown to stimulate type II collagen formation in the cartilage matrix.
What precautions must be taken when handling explants?
Careful pipetting is critical to avoid losing or damaging the explants.
How can the results be further validated?
Findings should be supported by data from human tissues and additional molecular techniques.
