Cell line • a cell line is a permanently established cell culture that will proliferate indefinitely given appropriate fresh medium and space • a cell culture developed from a single cell and therefore consisting of cells with a uniform genetic make-up • there is presence of several cell linkage either similar or distinct • generally. A cell strain is derived either from a primary culture or a cell line by the selection or cloning of cells having specific properties or characteristics which must be defined cell strains are cells that have been adapted to culture but, unlike cell lines, have a finite division potential. Cell culture refers to the removal of cells from an animal or plant and their subsequent growth in a favoriable artificial environment it becomes a continuous cell line it is also used in drug screening and development, and large scale manufacturing of biological compounds (eg, vaccines, therapeutic proteins). One of the most widely used continuous cell lines for virology is the hela cell line, which was derived in 1951 from henrietta lacks what is the origin of this amazing cell line in early 1951, ms lacks, a 31-year old mother of five children, was found to have a malignant tumor of the cervix.

Vaccines in novel continuous cell lines of mammalian origin as well as in insect cells has been made and consequently there is an increasing need for the re-evaluation of existing criteria for the acceptability of such cell lines. According to biotechnology 4u, continuous cell lines are derived from the surviving cells of a primary cell culture in cases where the cells in a primary culture are cloned, or transformed, continuous cell lines can be used to develop a secondary cell culture. A continuous cell line, tec (turbot embryonic cell line), was established from embryos at the gastrula stage of a cultured marine fish, turbot (scophthalmus maximus), and has been cultured for.

Summary the cell line ufl-ag-286 was established from the embryos ofanticarsia gemmatalis (lepidoptera: noctuidae) the cell line was characterized by isozyme analysis and from molecular weight determination of the restriction endonuclease bands of the mitochondrial dna.

Both cell lines had unique characteristics in multipotency in vitro: cell line 1–11 exhibited the potential to differentiate into osteoblastic and adipocytic cells, and cell line 1–17 performed osteoblastic, adipocytic, chondrocytic, and even neurocytic differentiations (fujii et al, 2008 tomokiyo et al, 2008.
