History of Cell Culture
In biological research, tissue culture refers to a method in which fragments of a plant or animal tissue are introduced into a new, artificial environment, where they continue to function or grow.
While fragments of a tissue are often used, it is important to note that entire organs are also used for tissue culture purposes. Here, such growth media as broth and agar are used to facilitate the process. Seed culture is the type of tissue culture that is primarily used for plants such as orchids. For this method, explants tissue from the plant are obtained from an in-vitro derived plant and introduced in to an artificial environment, where they get to proliferate.
In the event that a plant material is used directly for this process, then it has to be sterilized to prevent tissue damage and ensure optimum regeneration.
Embryo culture is the type of tissue culture that involves the isolation of an embryo from a given organism for in vitro growth. Embryo culture may involve the use of a mature of immature embryo. In doing so, the embryo is ultimately able to produce a viable plant. For embryo culture, the ovule, seed or fruit from which the embryo is to be obtained is sterilized, and therefore the embryo does not have to be sterilized again.
Salt sucrose may be used to provide the embryo with nutrients. The culture is enriched with organic or inorganic compounds, inorganic salts as well as growth regulators.
In practice, callus culture involves the growth of a callus composed of differentiated and non-differentiated cells , which is the followed by a procedure that induces organ differentiation.
For this type of tissue culture, the culture is often sustained on a gel medium, which is composed of agar and a mixture of given macro and micronutrients depending on the type of cells. Different types of basal salt mixtures such as murashige and skoog medium are also used in addition to vitamins to enhance growth.
Organ culture is a type of tissue culture that involves isolating an organ for in vitro growth. Here, any organ plant can be used as an explant for the culture process shoot, root, leaf, and flower. With organ culture, or as is with their various tissue components, the method is used for preserve their structure or functions, which allows the organ to still resemble and retain the characteristics they would have in vivo.
Here, new growth differentiated structures continues given that the organ retains its physiological features. As such, an organ helps provide information on patterns of growth, differentiation as well as development.
There are number of methods that can be used for organ culture. These include:. A protoplast is the term used to refer to cell fungi, bacteria, plant cells etc in which the cell wall has been removed, which is why they are also referred to as naked cells. Protoplasts may be cultured in the following ways:. Once a protoplast has regenerated a cell wall, then it goes through the process of cell division to form a callus, which may then be subcultured for continued growth.
Protoplast culture is an important method that provides numerous single cells that can be used for various studies. In protoplast culture, a number of phases can be observed. For plants, some of the special requirements include:. Some of the other types of tissue culture include:. Initiation Phase Stage 1. The initiation phase is the first phase of tissue culture. Here, the tissue of interest is obtained and introduced and sterilized in order to prevent any microorganism from negatively affecting the process.
It is during this stage that the tissue is initiated in to culture. Multiplication Phase Stage 2. The multiplication phase is the second step of tissue culture where the in vitro plant material is re- divided and then introduced in to the medium.
Here, the medium is composed of appropriate components for growth including regulators and nutrients. These are responsible for the proliferation of the tissue and the production of multiple shoots. Root formation Stage 3. It's at this phase that roots are formed. Hormones are required in order to induce rooting, and consequently complete plantlets. Tissue culture is applied in plant research for such purposes as the growing of new plants, which in some cases undergo genetic alterations.
Here, the plant of interest is taken through the tissue culture process and grown in a controlled environment. This process involves the use of small pieces of a given plant tissue. Once the tissue is obtained, it is then cultured in the appropriate medium under sterile conditions so as to prevent various types of microorganisms from affecting the process.
The following is a general procedure for plant tissue culture:. Medium preparation. Plant preparation. Transferring the plant material to a tissue culture medium. Cauliflower - partly submerged in medium with flower bud facing up. Rose with shoots at level with medium surface. African violet leaf laid directly in surface of medium. This procedure will result in the development of a callus, which then produces shoots after a few weeks. Once the shoots develop, then the plant section may be placed in the right environment well lit, warmth etc for further growth.
For plants, the medium culture acts as a greenhouse that provides the explant with the idea environment for optimum growth. This includes being free of microorganisms, nutrients as well as the right balance of chemicals and hormones. Some of the major reasons tissue culture is used for plants include:.
Micropropagation - This technique is used for the purposes of developing high-quality clonal plants a clone is a group of identical cells. This has the potential to provide rapid and large scale propagation of new genotypes. Somatic cell genetics - Used for haploid production and somatic hybridization. Transgenic plants - Used for expression of mammalian genes or plant genes for various species it has proved beneficial for the engineering of species that are resistant against viruses and insects.
In reality, there are numerous methods used for tissue culture given that there are different types of tissues that require specific conditions for the culture process yield desired results.
Both plant and animal tissue can be used for tissue culture purposes for a wide range of purposes. On the other hand, plant tissue culture may be used for cloning purposes, genetic modification of a given plant or simply to accelerate or increase yield of the plant of interest.
Tissue culture is therefore of great significance in biological studies due to its wide range of applications. The processes involved in tissue culture may be complex, requiring a lot of care to avoid such effects as contamination. Because of the complexities that may be involved in some of the steps, this may not be an experiment for everyone.

Plant Tissue Culture: Theory and Practice, Volume 5
Plant tissue culture has developed widely incorporated into biotechnology, the agricultural systems being a key factor to support many pharmaceutical and industrial outcomes. Since there is vast progress in plant culture and its application has emerged having great diversity in the science filed. Due to development and desire to grow on high scale production in the past few decades, tissue culture techniques were manipulated for improvement of plant growth, biological activities, transformation, and secondary metabolites production. A significant advance in techniques has been sought to deal with problems of low concentrations of secondary metabolites in whole plants.

Essentially, cell culture involves the distribution of cells in an artificial environment in vitro which is composed of the necessary nutrients, ideal temperature, gases, pH and humidity to allow the cells to grow and proliferate. Whereas pieces of tissue can be put in the appropriate culture to produce cells that can then be used for culture explant culture , cells from tissues soft tissue can be obtained through enzymatic reactions. Such enzymes as trypsin and proname are used to break down the tissue and release the desired cells. However, cells that continue to proliferate indefinitely after the first subculture under special conditions are referred to as cell lines. These particular cells tend to have been passaged for a long period of time, which causes them to acquire homogenous similar genotypic and phenotypical traits.

From the ancient Romans, through the Middle Ages, to the late of the nineteenth century, the Aristotelian doctrine of spontaneous generation was one of the most basic laws. Even the invention of the microscope and investigations of Leeuwenhoek and Hook did not disprove the Aritostelian doctrine. Finally, in the eighteenth century, the spontaneous generation doctrine was laid by Louis Pasteur. Moreover, in the first decade of the eighteenth century, nucleus was observed in plant and animal tissues, and Virchow and other scientists presented the view that cells are formed via scission of preexisting cells. In the first decade of the twentieth century, Ross Harrison developed the first techniques of cell culture in vitro, and Burrows and Carrel improved Harrison's cell cultures. On the basis of knowledge about the cell cycle and gene expression regulation, the first therapeutic proteins were produced using mammalian cell cultures.
Чатрукьян еще раз обвел глазами пустую лабораторию и нахмурился. - Где же он, черт возьми. Глядя на оживающий монитор, он подумал, известно ли Стратмору, что в лаборатории систем безопасности нет ни души. Подходя к шифровалке, он успел заметить, что шторы кабинета шефа задернуты. Это означало, что тот находится на рабочем месте.
Никаких. Продолжай движение. ГЛАВА 78 Джабба обливался потом перед спутанными проводами: он все еще лежал на спине, зажав в зубах портативный фонарик. Ему было не привыкать работать допоздна даже по уикэндам; именно эти сравнительно спокойные часы в АНБ, как правило, были единственным временем, когда он мог заниматься обслуживанием компьютерной техники.
Что тебя тревожит. Сьюзан заставила себя сесть. Она полагала, что Стратмор уже закончил телефонный разговор и сейчас придет и выслушает ее, но он все не появлялся. Пытаясь успокоиться, она посмотрела на экран своего компьютера. Запущенный во второй раз Следопыт все еще продолжал поиск, но теперь это уже не имело значения.
При первых же признаках беды он тут же поднял бы тревогу - а в этих стенах сие означает, что он позвонил бы .
