Concepts and Terminology
- A freshly isolated cell culture is referred to as primary culture.
- A cell culture maintained as an attached monolayer or cell suspension is called cell line.
- Tissue culture in animal biotechnology refers to the process of growing cells in controlled conditions, often outside their natural environment.
- In vitro organ culture involves maintaining organ tissues under laboratory conditions to study their functionality and development.
- The major goal of animal biotechnology is to improve the efficiency of animal production and health, along with developing biopharmaceuticals.
- Tissue culture is crucial as it allows for the manipulation and study of cells in a controlled environment, contributing to advancements in various biological fields.
Applications and Techniques
- Major applications of animal cell culture in life sciences include drug development, vaccine production, and genetic engineering.
- Defined conditions for animal cells to grow outside their original organ or tissue include proper temperature, pH balance, nutrient availability, and sterile environment.
- Animal cells can be induced to grow outside their origin through techniques like enzymatic digestion and mechanical dissociation.
- Tissue culture's importance lies in its ability to provide a reproducible and controlled environment for studying cellular behavior, development, and the effects of various substances on cell function.
