What is tissue culture in animal biology?
The in vitro maintenance and/or proliferation of animal cells, tissues, or organs.
What are the main disadvantages of cell and tissue culture?
Loss of differentiated characteristics, difficult maintenance, limited yield, dedifferentiation, instability, aneuploidy, and loss of tissue organization.
What is cell culture in biological research?
Growth of cells as an adherent monolayer or in suspension in culture medium.
What is a primary explant culture?
Growth of a tissue fragment on a solid substrate with cell attachment and migration.
Tissue culture definition
In vitro maintenance or proliferation of animal cells.
Advantages of cell culture
More control, homogeneous samples, shorter times.
Main disadvantages of cell culture
Loss of differentiation, dedifferentiation, instability.
Cell culture types
Adherent monolayer or suspension cultures.
Primary explant culture
Grows tissue fragment on a solid substrate.
Organ culture
Maintains whole organ or embryo in 3D.
Laminar-flow hood role
Protects culture from dust, contamination.
Answer 16 questions on Animal Cell Culture Biotechnology.
