[vc_row][vc_column][vc_column_text css=\u201d\u201d]Cell culture represents a key tool in modern scientific research. Over the past decades, scientists have developed advanced cell culture techniques<\/strong> to isolate individual cells from tissues and obtain homogeneous cell populations that can be maintained, manipulated, and multiplied in vitro<\/em>.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

The<\/span> 4 <\/span>types<\/span> of<\/span> cell<\/span> culture: <\/span>definition<\/span>, <\/span>differences<\/span>, and <\/span>application<\/span> examples<\/span><\/span>\u00a0<\/span><\/h2>\n

Understanding the different <\/span>types of cell culture<\/strong> is essential, as each presents unique characteristics and is suited to specific experimental or production goals.<\/span>\u00a0<\/span><\/p>\n

Primary cultures\u00a0<\/strong><\/h3>\n

These are obtained directly from a tissue or organ. They retain the original characteristics of the source tissue, although their proliferation capacity is limited. Primary cultures are often used in early research stages and can give rise to secondary cultures.<\/span>\u00a0<\/span><\/p>\n

Secondary cultures\u00a0<\/strong><\/h3>\n

Derived from primary cultures, these can be subcultured in fresh vessels for maintenance over weeks or months. Secondary cultures not only allow cells to be maintained for extended periods but also enable the study of specialized functions such as intestinal absorption or compound metabolism.<\/span>\u00a0<\/span><\/p>\n

For example, this type of <\/span>cell culture<\/span><\/b> can be applied in <\/span>in vitro<\/strong><\/a> bioavailability assays<\/strong> using human intestinal cell lines like Caco-2, to evaluate how functional ingredients, nutraceuticals, pharmacological, or bioactive compounds are absorbed after passing through a dynamic digester simulating the human gastrointestinal process.<\/a><\/strong><\/span>\u00a0<\/strong><\/p>\n

Cell lines \u2013 continuous cultures\u00a0<\/strong><\/h3>\n

Some cells can acquire the ability to divide indefinitely, either through genetic manipulation (such as the introduction of telomerase or oncogenes) or spontaneously, as in many rodent cells. These cell lines are widely used due to their stability, homogeneity, and ease of storage in liquid nitrogen. They can also be cloned to generate genetically identical populations, which allows researchers to study specific mutations.<\/span>\u00a0<\/span><\/p>\n

Hybridomas\u00a0<\/strong><\/h3>\n

Resulting from the fusion between B lymphocytes and tumor cells, hybridomas are <\/span>cell lines<\/span><\/b> capable of producing monoclonal antibodies indefinitely. This technology makes it possible to obtain highly specific antibodies for the treatment and detection of multiple diseases.<\/span>\u00a0<\/span><\/p>\n

How<\/span> are <\/span>cells<\/span> obtained<\/span> in <\/span>cell<\/span> culture?<\/span><\/span>\u00a0<\/span><\/h2>\n

Cell culture<\/strong> refers to the set of techniques that allow living cells to be maintained outside their organism while preserving their physiological properties. These cells can grow either in suspension or as a monolayer and can be obtained from various biological sources.<\/span>\u00a0<\/span><\/p>\n

To establish cultures from tissues, the first step is to isolate individual cells by separating them from the extracellular matrix that keeps them together. This is achieved using proteolytic enzymes and chelating agents such as EDTA, which interfere with cell adhesion. The result is a mixed cell suspension that can then be purified according to the desired cell type.<\/span>\u00a0<\/span><\/p>\n

Common methods for separating cell types include:\u00a0<\/strong><\/p>\n
