. Biology in America. Biology. The Organization of the Egg 199 in cancer, certain cells possess the power of seemingly un- limited growth, increasing- at the expense of other tissues, running wild within the body, and finally destroying it as a result of their riotous living. This power of seemingly un- limited growth of the cell may in many cases be initiated artificially. Unquestionably the most important of Harrison's results. A Piece of Growing Tissue The (lark center is the original tissue, the brandling boilies radiating out from it are the growing cells. It has been possible to cultivate in glass cells many different kinds of tissue, including those from man himself. This method has been used for studying the growth and reaction of cancer cells, and may throw light on the cause of this dreail malady. After Lambert and Hanes, "Journal of Experimental Medi- ; Vol. 13. on nerve growth was his development of the method of grow- ing tissues outside of the animal body. He transplanted bits of the central nervous system of the tadpole to drops of coagulable lymph from the frog, and by placing these in a glass cell under the microscope, he was able to follow the growth of the nerve fibers. More recently a large number of workers, mostly Americans, have developed Harrison's method and applied it to both embryonic and adult tissues of birds and mammals. The method has been applied to the.
