Q & A

What is the main focus of the Cell Culture Technology course introduced in the transcript?

The course aims to provide practical knowledge about cell culture technology, which is commonly associated with laboratory training in biology, chemistry, and environmental science.

What is cell culture technology often mistakenly identified as?

It is often mistaken for just a technique for growing cells artificially in a controlled environment, without recognizing the underlying philosophy and scientific principles.

What historical significance does cell culture technology hold?

Cell culture technology has a history of over a hundred years, with its first major publication occurring around 1908-1912, before World War I.

What are explants, and why are they significant in cell culture?

Explants refer to tissue samples taken from an organism for cultivation. They are significant as they serve as the basis for initiating cell culture experiments.

What are some of the key techniques mentioned that are related to spectroscopy?

The techniques mentioned include Raman spectroscopy, FTIR (Fourier Transform Infrared Spectroscopy), and NMR (Nuclear Magnetic Resonance), all of which are fundamental for understanding and applying various scientific principles.

How does the transcript differentiate between in vivo and in vitro conditions?

In vivo refers to studying cells within the living organism, while in vitro refers to growing cells outside of the organism in a controlled environment, such as in a culture dish.

What role does the extracellular matrix play in cell culture?

The extracellular matrix provides structural support and helps to keep cells anchored together. Disruption of this matrix allows for the separation of cells in culture.

What is the 'theory of omni cellule' referenced in the transcript?

The theory of omni cellule states that all cells originate from previously existing cells, emphasizing the continuity of cellular life and division in cell culture.

What potential issues can arise when cells are cultured outside of their natural environment?

When cultured outside their natural environment, cells can behave differently, including the potential for normal cells to become cancerous due to the absence of regulatory growth factors.

Why is it important to understand the history and philosophy behind cell culture technology?

Understanding the history and philosophy is crucial for grasping the techniques and innovations in the field, allowing for better comprehension of current practices and advancements in cell culture technology.
