The term "cell strain" refers to a population of cells that have been derived from a single cell and have been allowed to reproduce in a culture dish. The phonetic transcription of this term in IPA is /sɛl streɪn/. The word "cell" is pronounced with the short e sound, represented by the phoneme /ɛ/. The word "strain" is pronounced with a long a sound, represented by the phoneme /eɪ/. The pronunciation of this word may vary depending on regional accents or dialects.
Cell strain refers to a population of cells that originates from a single cell source and has been subject to a series of passages or divisions. It is a term commonly used in cell culture and biotechnology to describe a specific group of cells that have been propagated and expanded in vitro, typically in a laboratory setting.
The process of creating a cell strain involves isolating a single healthy cell and allowing it to proliferate and grow in a controlled environment. As the cells divide, they form a population of genetically identical cells called a clone. These cells can be further propagated through several passages, in which a small subset of cells is transferred into a new culture vessel where they can continue to grow and multiply.
Cell strains are useful in scientific research as they provide a homogeneous and well-defined population of cells that can be used for various experiments and investigations. They allow researchers to study specific cell types, characterize their properties, and observe their behavior under different conditions.
Furthermore, cell strains are utilized in the production of biological products, such as therapeutic proteins or vaccines. By establishing a cell strain with desirable characteristics, it can serve as a consistent and renewable source of cells for large-scale manufacturing processes.
Overall, cell strain is a term used to describe a population of cells that has been derived from a single cell source and has undergone repeated passages, serving as a valuable tool for scientific research and biotechnology applications.
The word "cell" originated from the Latin word "cella", which means "small room" or "storeroom". The term "strain" is derived from the Old French word "estreindre", which means "to bind tightly" or "narrow". The etymology of "cell strain" comes from the combination of these two words.
In the context of biological research, a "cell strain" refers to a population of cells derived from a single source that share similar genetic characteristics and growth patterns. Cells in a strain are typically cultivated and maintained in laboratory settings for experimental purposes.
