Mammalian Cell Culture Media

Overview of the topic introduction, main discussion and conclusion.

Introduction

Mammalian cell culture entails removing animal cells from the body and propagating them in a suitable artificial environment ex vivo.

Creating In Vitro Environment

The objective is to recreate the in vivo conditions within an artificial, in vitro environment.

Nutrient Provision in Body

In the biological system, nutrients are carried to the cells by blood, a feature recapitulated in cell culture media.

Cellular and Microbial Differences

Animal and microbial cells, while functionally similar, have distinct structures, requiring different types of media.

Complexity in Mammilian Cell Growth Medium

The complexity of mammalian cell culture medium arises from the multitude of cell types in the organism, each performing a unique function, producing and secreting various molecules that circulate in the extracellular fluid.

Maintaining Mammalian Cell Culture Media Conditions

Maintaining ideal conditions for cell culture media involves maintaining precise values of isotonic conditions, pH, and temperature, with temperature closely matching body temperature.

Critical Components of Animal Cell Culture Media

Essential components such as inorganic salts, carbohydrates, amino acids, vitamins, fatty acids, peptides, and trace elements constitute the basis of animal cell culture media.

Serum Supplements

Serum or serum replacements are commonly used to supplement the basic elements in the medium.

Serum Composition and Origin

Blood, comprising white blood cells, red blood cells, platelets, and plasma, is the source of serum. Clotting components are removed, leaving the serum. Fetal bovine serum is a prevalent choice for in vitro cell culture.

Different Categories of Media

Different types of media include serum, serum-free media, animal-free media, and low-protein media.

Defined vs. Non-Defined Media

Defined media contains compounds with known concentrations, while non-defined media comprises a mixture of components with unspecified concentrations.

Essential Amino Acids

Glutamine, isoleucine, leucine, lysine, phenylalanine, threonine, tryptophan, valine, methionine, and histidine are essential amino acids.

Nonessential Amino Acids

Includes alanine, arginine, asparagine, aspartic acid, glutamic acid, glycine, proline, serine, tyrosine.

Defining Components

Amino acids are essential for protein synthesis, carbohydrates as the source of energy and proteins and peptides, fatty acids and lipids, vitamins, and inorganic salts contribute various roles in the culture.

Trace Elements

Essential micronutrients for various biological processes, often originating from serum and hence necessary additions in serum-free media.

pH Indicator

Phenol red, a pH indicator with no nutritive value, aids in monitoring proper pH values in the media.

Bacterial Contamination and Antibiotic Use

Antibiotic use in culture media can both prevent and encourage certain contamination issues, including antibiotic resistance and masking of low-level contaminants.

Conclusion

Successful mammalian cell culture in vitro necessitates a balanced mixture of nutrients, including amino acids, monosaccharides, vitamins, inorganic ions, trace elements, additional factors such as hormones, growth factors, and attachment factors. Phenol red is used for monitoring the pH. It is not advisable to routinely use antibiotics in the culture media.
