HARRISON, Ross Granville (1870-1959), American zoologist, who made contributions to experimental embryology and discovered techniques Tissue the techniques of Tissue culture.
When a person sustains a wound, the exposed raw surface is soon covered by a film of blood or plasma that oozes from the injured skin capillaries. When this film dries, it leaves a scab under which newly formed connective Tissue cells multiply and form new Tissue and fibers. The cells of the capillaries also multiply and invade the Tissue in solid loops that soon become hollow tubes through which blood is supplied to the growing tissue. When the lost Tissue is replaced, the capillaries start disappearing, and the red color of the Tissue fades as the number of capillaries decreases.
With Tissue culture techniques it is possible to remove plant or animal, including human, tissues from the intact organism, separate the tissues by mechanical or chemical means into suspensions of loose cells, and adapt such cells to growth in liquid, either floating freely or anchored to a glass substratum. In addition to normal tissues, a large number of animal and human tumors have been successfully cultured. In Tissue culture the cell populations grow and divide in the same manner as populations of microorganisms. |
