Keith R. Porter

Keith Roberts Porter was a Canadian-American cell biologist. He created pioneering biology techniques and research using electron microscopy of cells. Porter also contributed to developing other experimental cell culture and nuclear transplantation methods. He was also responsible for naming the endoplasmic reticulum, working on the 9 + 2 microtubule structure in the axoneme of cilia, and coining the term "microtrabecular lattice." Collaborating with other scientists, he contributed to understanding cellular structures and concepts such as compartmentalization, flagella, centrioles, fibrin, collagen, T-tubules and sarcoplasmic reticulum. He also introduced microtome cutting.
