?What is tissue culture In vitro culture (maintain and/or proliferate) of cells, tissues or organs. Types of tissue culture • Cell culture • Primary explant culture • Organ culture 2 Three major categories of tissue culture Cell culture: Adherent monolayer on a solid substrate (various cell types) or suspension in the culture medium (few cell types). Primary explant culture: A fragment of tissue attachment and migration occurs in the plane of the solid substrate. Organ culture: A spherical or ...
Methods of Plant Tissue Culture: Plant tissue culture includes two major methods: (A) Type of in vitro growth-callus and suspension cultures. (B) Type of explant— single cell culture, shoot and root cultures, somatic embryo culture, meristem culture, anther culture and haploid production, protoplast culture and somatic hybridisation, embryo culture, ovule culture, ovary culture, etc. Types of Plant Tissue Culture: Callus and Suspension Cultures: In callus culture, cell division in explant forms a callus. Callus is irregular unorganised and undifferentiated mass ...
The term tissue culture may be defined as the process of in-vitro culture of explants in nutrient medium under aseptic conditions. It includes the culture of cell, organ culture and suspension culture etc. German botanist Gottlieb Haberlandt was regarded as father of tissue culture. The basis of tissue culture is totipotency of cell. German botanist Gottlieb Haberlandt first attempted to culture plant tissues ‘in vitro’. He started his work in 1898. He used cells from palisade tissues of leaves ...

ABSTRACT • Embryonic stem (ES) cells are typically derived from the inner cell mass of the preimplantation blastocyst and can both self-renew and differentiate into all the cells and tissues of the embryo. Because they are pluripotent, ES cells have been used extensively to analyze gene function in development via gene targeting. The embryonic stem cell is also an unsurpassed starting material to begin to understand a critical, largely inaccessible period of development. If their differentiation could be controlled, they ...
