What are human cell lines?
Human cell lines are organic tools used in biological, genetic and medical research. Scientists have learned to maintain plant and animal cells alive after their removal from organisms, sometimes for an indefinite period. These cells, called cellular cultures, can be made to multiply as in the body and create new cells almost identical to the originals. These cell cultures, called cellular lines, are invaluable tools in the development of medicinal products and vaccines. Human cell lines offer insight into human biology that cell lines from plants or other animals can not always provide. In the 20th century, scientists and medical scientists discovered great value in maintaining such cell cultures. They proved to be vital in the development of vaccines for polio, measles and other viral diseases. As genetic research has progressed, the Human Cell Lines offered to insight into human genetic make -up. There are indications that such research can help fight cancer and childrenDIFICAL DISEASE.
The first cell culture did not last long before death or became unnecessary. Scientists soon learned how to maintain such cultures in organic solutions that simulated the nursing environment of the body. While some, such as blood cells, can be kept in a liquid solution, others must be glued to a solid surface to survive. The scientific advantage of the use of such cells is that they will be without genetic variations. Thus, they create a perfect control group that can be used for comparison with other cells that have been changed by adding biological materials such as viruses or vaccines.
In order to face the short life of some cells, human cell lines have been encouraged to grow and reproduce; Cell lines can then be distributed to the spoil laboratory in the same areas of research. Some of these human cell lines can be kept indefinitely, sometimes long after it givesRce of the cells died. For this reason, they are colloquially referred to as immortal cell lines. These cells can be genetically manipulated by adding new genetic material. The resulting changes provide new knowledge about genetic markers for diseases such as cancer.
In 2010, the popular book of science Immortal Life of Henriett Lacks Rebecca Glass brought knowledge of human cell lines from medical laboratories. The glass watched the cellular line used in cervical cancer research back to the original owner, Lacks, an African American woman who died of this disease in 1951. Despite the wide use of the cell line, the Lack family did not know about Henrietta's contribution to medical science for 25 years. The media coverage of the book Skloot inspired extensive interest in human cellular lines, lacks itself and the cell line that was created is still called Hela biologists and scientists around the world.
