Monolayer culture refers to a type of culture in which cells are grown in a single layer on a flask or Petri dish containing the culture medium while suspension culture refers to a type of culture in which single cells or small aggregates of cells multiply while suspended in an agitated liquid medium.

What is monolayer culture?
A monolayer culture is an anchorage-dependent culture. It grows attached to the surface of a flask. ... Some suspension cultures form floating aggregates. It is possible to have a third, mixed culture which contains both flat, adherent cells and floating, rounded cells in the medium.
What are suspension cultures?
A cell suspension or suspension culture is a type of cell culture in which single cells or small aggregates of cells are allowed to function and multiply in an agitated growth medium, thus forming a suspension. Suspension cultures are used in addition to so-called adherent cultures.
What is the difference between adherent and suspension cultures?
Adherent cells grow by remaining attached to a solid substrate, such as the bottom of a tissue culture flask. ... Suspension cells will float and grow suspended in the culture medium, so they don't need to be mechanically or chemically removed.
What is suspension cell line?
In general terms, cell lines derived from blood (e.g. lymphocytes) grow in suspension cultures. Cells may grow as single cells or in clumps (e.g. EBV transformed lymphoblastic cell lines). For these types of cell lines subculture by dilution is relatively easy.
What is a secondary culture?
Secondary cell cultures When a primary culture is sub-cultured, it becomes secondary culture or cell line. ... The process involves removing the growth media, washing the plate, disassociating the adhered cells, usually enzymatically. Such cultures may be called secondary cultures.
What is Histotypic culture?
Histotypic culture is defined as three‐dimensional culture of one cell type, while the term organotypic implies the interaction of two or more cell types from a complex tissue or organ.
What are the advantages of suspension culture?
Advantages : The nutrients can be continually adjusted. This system can be scaled for large scale production of the cells. A whole plant can be regenerated from a single plant cell. Disadvantages : The productivity of suspension cultures decreases over extended subculture periods.
Why is suspension culture constantly agitated?
For the preparation of suspension culture, callus is transferred to a liquid nutrient medium and is agitated. Cells of callus are separated due to agitation. Constant agitation at 100- 250 rpm serves the purpose of aeration, mixing and prevention of aggregation.
What is callus and suspension culture?
Callus and cell suspension can be used for long-term cell cultures maintenance. This chapter describes procedures for the induction of somatic embryos of garlic, keeping a regeneration capacity for more than 5 yr, as well as the maintenance of a tobacco suspension culture (NT-1 cells), for more than 10 yr.
Do macrophages divide in culture?
In vivo and in vitro studies done in murine bone marrow have shown that monoblasts and promonocytes are the most immature, dividing cells of the mononuclear phagocyte cell line; monocytes and resident macrophages do not divide. ... The cells of macrophage cell lines are transformed cells that proliferate continuously.
Why do we culture cells?
Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis.
How long can cells survive at room temperature?
The most robust cells tolerated up to 3 weeks of transport (e.g. U2OS and MRC5) at ambient temperature (20–22°C).
