Cell differentiation

The process by which a relatively non-specialized cell becomes a very specialized is called 'differentiation' and affects both the embryo is an individual adult. During embryonic development, many cell types are generated from the fertilized egg cell, to get the range of cells that characterize the adult subject. The route followed by each embryonic...

Cell division

Most cell undergoes division, ie, the formation of two daughter cells identical to the parent cell. This event occurs at the end of the cell cycle, which represents the set of modifications that must be met from the moment in which a cell is formed at the moment in which it divides into two daughter cells. The division is preceded by stages in...

How to prepare a cell culture

The first stage in the preparation of a cell culture consists in isolating the desired population of cells from a tissue fragment; in an initial mechanical disaggregation of the tissue is followed by enzymatic digestion, to degrade the extracellular matrix that surrounds and holds the cells together. The resulting cell population is heterogeneous,...

The culture of plant cells

The techniques for the cultivation of plant cells were developed in the fifties of the twentieth century., When he began to realize that the crops have the potential to produce a wide range of molecules useful in various areas, and currently many types of plant cells can be grown in test tubes. Plant cells are surrounded by a cell wall rather...

How to feed the cells in Tissue culture

In the living cells remain viable thanks to the contribution of nutrients, guaranteed by the vascular system and, via the capillary network, nourishes the tissue at the cellular level and removes waste products derived from cellular metabolism . In vitro functions vascular vicariate are from the culture medium, a liquid medium highly nutritious....

Cultured cells and tissues

The cell culture techniques have allowed to study the behavior of cells outside of the living organism in artificial conditions which reproduce, as faithfully as possible, the microenvironment of the tissue or organ from which they derive. The experiments performed on cultured cells are defined in vitro to distinguish them from those in vivo that...
