The tissue culture treatment process involves exposing a polystyrene microplate to a plasma gas in order to modify the hydrophobic plastic surface to make it more hydrophilic. The resulting surface carries a net negative charge due to the presence of oxygen-containing functional groups such as hydroxyl
Hydroxy group
A hydroxy or hydroxyl group is the entity with the formula OH. It contains oxygen bonded to hydrogen. In organic chemistry, alcohol and carboxylic acids contain hydroxy groups. The anion, called hydroxide, consists of a hydroxyl group.

When was tissue culture first used?
An early attempt at tissue culture was made in 1885 by German zoologist Wilhelm Roux, who cultivated tissue from a chick embryo in a warm salt solution. The first real success came in 1907, however, when American zoologist Ross G. Harrison demonstrated the growth of frog nerve cell processes in a medium of clotted lymph. French surgeon Alexis Carrel and his assistant Montrose Burrows subsequently improved upon Harrison’s technique, reporting their initial advances in a series of papers published in 1910–11. Carrel and Burrows coined the term tissue culture and defined the concept. Thereafter, a number of experimenters succeeded in cultivating animal cells, using as culture media a variety of biological fluids, such as lymph, blood serum, plasma, and tissue extracts. In the 1980s and ’90s, methods were developed that enabled researchers to successfully grow mammalian embryonic stem cells under artificial conditions. Those breakthroughs ultimately enabled the establishment and maintenance of human embryonic stem cell lines, which advanced researchers’ understanding of human biology and greatly facilitated progress in therapeutics and regenerative medicine.
How are cultures grown?
Cultures are usually grown either as single layers of cells on a glass or plastic surface or as a suspension in a liquid or semisolid medium. To initiate a culture, a tiny sample of the tissue is dispersed on or in the medium, and the flask, tube, or plate containing the culture is then incubated, usually at a temperature close to that ...

What is the culture environment?
Culture environments. Cells may be grown in a culture medium of biological origin such as blood serum or tissue extract, in a chemically defined synthetic medium, or in a mixture of the two. A medium must contain proper proportions of the necessary nutrients for the cells to be studied and must be appropriately acid or alkaline.
What are the two types of cultures?
There are two main types of cultures: primary (mortal) cultures and cultures of established (immortal) cell lines. Primary cultures consist of normal cells, tissues, or organs that are excised directly from tissue collected by biopsy from a living organism. Primary cultures are advantageous in that they essentially model the natural function ...
Why are primary cultures beneficial?
Primary cultures are advantageous in that they essentially model the natural function of the cell, tissue, or organ under study. However, the longer the samples are maintained in culture, the more mutations they accumulate, which can lead to changes in chromosome structure and cell function.
What is tissue culture technique?
Plant tissue culture technique has become an important tool in the hands of the plant biotechnologists. A number of research investigations have been reported for the production of biologically active constituents using plant tissue culture techniques. Cassia senna Linn. (Caesalpineaceae) is an important medicinal plant, which has been widely used in Ayurveda. The active chemical components of the plant are anthraquinone glycosides – sennosides, especially sennosides A and B, which are responsible for the purgative action. A protocol for tissue culture of C. senna is established in different morphogenetic media and in vitro -grown tissues/cells were analyzed for their biosynthetic potential. 24 The results of the study indicate that the in vitro- cultured partially organized cells of C. senna inherited the biosynthetic potential, which can be exploited for production of sennosides on a large scale under proper growth conditions. The whole venture to explore the cultures of ayurvedic medicinal plants for bioactive constituents was undertaken all over the world and soon it blossomed into a new technology that has affected the phytochemical industry to a large extent. Commercial viability and economic feasibility still remain the decisive factors in the industrial production of such metabolites from the cultures. The range of metabolites produced by the callus and cell suspension cultures includes alkaloids, glycosides, flavonoids, and others. The cell suspension cultures are particularly capable of synthesizing such molecules and are regarded as potentially suitable systems for producing the metabolites of high economic value. They produce the bioactive molecules equivalent to or higher in yields to the plants from which they are derived. 25 Plant cell culture provides an alternative method for production of plant secondary metabolites.
What is plant tissue culture?
Plant tissue culture techniques are based on the ability of plant cells and tissues to grow on synthetic media under aseptic and controlled environmental conditions such as pH, light, temperature, and humidity. A wide range of synthetic media such as Murashige and Skoog (MS) medium, Linsmaier-Skoog (LS) medium, Schenk-Hilderbrandt (SH), woody plant medium (WPM), and the Nitsch and Nitsch (NN) medium are used in the plant tissue culture. Plant tissue cultures are initiated by various methods to produce a complete plant. The following methods are extensively used in laboratory (Fig. 23.1 ).
Why is explant culture important?
It is one of the oldest tissue culture techniques. Benefit of using explant culture for toxicological studies is that it holds histological architecture. It is widely used for study of carcinogens, environmental radiations or role of hormones. It has advantage in tissue engineering to mimic the organ-like structure. One more advantage of explant culture over total organ culture system is that it gives better visual results for experiments like immunohistochemistry as multiple precision-cut tissue slices can be obtain [21]. Explant culture of many types of organs such as liver, kidney, bladder, bronchus, esophagus, and skin has been successfully done. The drawback of this model is that the availability of nutrient and oxygen is limited to internal cells of explant and damage of few cells during explant slice preparation. These limitations can be surmounted by advanced tissue slice cutter which makes explant very thin and uniform.
How do cell survival curves work?
A cell survival curve describes the relationship between the absorbed dose of radiation and the proportion of cells that survive in the sense that they are able to grow into a colony, thereby demonstrating retention of their reproductive integrity. 10 With modern tissue culture techniques, it is possible to establish cell lines from many different tissues and tumors. If these cells are seeded as single cells and exposed to radiation or to some other cytotoxic agent, it is then possible to count the proportion of cells that are able to form macroscopic colonies after graded doses of the cytotoxic agent. Cell survival curves for mammalian cells have a characteristic shape. If surviving fraction is plotted on a logarithmic scale against dose on a linear scale, the curve has an initial slope at low doses, at which the surviving fraction seems to be an exponential function of dose (Fig. 1-11 ). As the dose is increased, the curve bends and becomes progressively steeper. At very high doses, the curve tends to become straight again (i.e., the surviving fraction returns to being an exponential function of dose). Over the first few decades of survival, survival curves for mammalian cells closely approximate that of a linear quadratic form expressed as follows:
What is tissue culture plastic?

- We frequently get asked questions like – why aren’t there more Nepenthes edwardsiana in tissue culture? While the rarity of N. edwardsiana is a partial answer, it’s also due to how difficult Nepenthesare to tissue culture. It appears that Nepenthes have an endogenous relationship with a bacteria, a fungus, or both. But since tissue culture requires a sterile environment, the challenge …
