THE LIVING CELL

The Cell, the basic constituent of all living organisms,continues to fascinate us, for, it holds within its core the very secret of life. Today, with the aid of cutting edge-technology, scientists are making use of cell-therapy and manipulation of genes for treatment of various diseases, including cancer. “The Song of the Cells”, a recent book by Siddharth Mukherjee, Pulitzer Prize winner, takes us through the exhilarating journey of cell research and describes its new possibilities.

The Cell All of us know about the Cell; cells group together to form tissues, tissues into organelles, and organelles into the whole organisms. Some organisms like the bacteria, of course, are unicellular.

 Although Robert Hook, the English polymath, and, Antonie Van Leeuwenhoek, a Dutch cloth merchant, discovered cells under the microscope in 1600, it took several centuries after that for scientists to unravel the structure and functioning of the Cell.

Today we learn that a cell comprises of the nucleus having the genetical material tucked within, the mitochondria, or the cell’s power house, Ribosomes involved in protein synthesis, the Golgi apparatus connected with transport, sorting and modification of both protein and lipid, vacuoles for eliminating wastes, plastids in plants which helps in photosynthesis etc. Plants cells are bound by cell walls, whereas, animal cells have only cell membranes.

Stephen Sir &What he taught usWhen I think about the Cell, I can’t help remembering Stephen Sir.It seems only yesterday that we were sitting in hisCytology class, listening to serious lectures on the Cell, its structure and functions.

Sir always looked too old for his age, with veryfew hairs standing erect on his bald head. He wore clothes that didn’t fit him.He walked with a slight stoop. He looked like a man in deep thoughts; there were furrows on his forehead. No wonder, we, his students, aptly gave him the nick-name him ‘wet hen’. However, to his credit, he led us to the hither to unknown world of Cells, when new research findings on Cells had just started getting published. He gave us innumerable references from top scientific journals, ensuring that we were fed with the latest information. Noting down all those tedious details did not give us any chance to chat or laugh, as we did in other classes.

In our practical classes we started looking at the cells, especially the stained chromosomes in the cells of Onion roots, grown in petri-dishes, crushed and stained. This opened before us a new world, confirming what we already learned in our theory classes.

Years passed by, and I chose a non-scientific profession. Even then, I used to come across the latest research findings on cells, especially the Human Genome Project and the like, from time to time. I had no problem relating to the latest discoveries, for, Stephen Sir had laid the foundations of cell studies so firmly in our minds. In my last visit to my nativeplace, I came to know, with deep regret, that Sir had passed away, sometime ago. However, the knowledge he painstakingly imparted in us still lives in our minds.

The Song of the Cell

There are numerous text books, articles and scientific papers describing the functioning of the cells. However, the book entitled “The Song of the Cells” is a class apart. Written by Siddhartha Mukherjee, it is a fascinating foray into the life of cells. I came across this book after reading an interview of Mukherjee in a leading newspaper. By then, his book had already started making waves. There were raving reviews. Those prompted me to get a copy of the book.

Siddhartha Mukherjee is an Associate Professor of Medicine at Columbia University and a cancer physician and researcher. A Rhodes scholar, he graduated from Stanford University, University of Oxford and Harvard Medical School. He was the winner of Pulitzer Prize in 2011.

The booknarrates the history of research into the biological and medical aspects of the cells, painstakingly carried out by scientists, since the 17th century. We come across the description about the structure and functions of the cells, organization of the cells into tissues, organelles and organisms. It gives us a graphic description of the blood cells, anti-bodies, B cells, T-cells, platelets and neutrophils. It tells us about cell division, cell death, cell repairs, and cell regeneration. It discusses leukemia and other types of cancers and auto-immune diseases. It also shares the exciting developments and future possibilities in cell therapy and gene manipulation. And finally, he discusses “The Song of the Cells.”

Had he been alive, Stephen Sir too could have reeled out all the facts relating to cells and would have given an account of the latest developments in the field. But any comparison is unfair in this regard, as one was a dedicated teacher, and the other, a gifted science writer. Here not only the cells, but also the scientists, their experiments, the laboratories, the people who are subject to experiments---all come alive. It looks at each patient with sensitivity and compassion. He explains difficult concepts on the basis of his own experiments or experiences or through personal stories. The whole text is interspersed with the life stories of scientists, the despair or courage of the patients and the trial and errors in cell research.No wonder the Washington Post wrote about the book thus “----(He) swaddles his medical rigor with rhapsodic tenderness, surprising vulnerability and occasional flashes of pure poetry---"Yes, there is the fine blending of science and poetry. One generally finds that at the ethereal level of thoughts,the boundary between science and poetryblurs, and they become indistinguishable from one another.

The book gives us many insights. It explains why the body’s immune system does not attack the body’s own cells, why in cancer cells divide without control, why in Arthritis stem cells remain inactive and the like. Latest experiments in cell therapy and gene manipulation provide us new information. Future possibilities are also indicated.

Behind the dramaAfter reading the book I started thinking-what is behind the pattern- the architecture of the cell, its organization and methodic division, orderly replication of chromosomes, synthesis of countless number of proteins through which the genes express themselves and control each and every activity of the cell, the capacity for cell repairs and regeneration, and a host of other things. Some scientists believe in intelligent design and a designer behind the patterns we witness in nature. The prevailing view is that nature is blind; evolution takes place randomly. The constant flux of creation and destruction takes place in nature. Organisms evolve trough natural selection. The quintessential pattern remains the same in all organisms, although they diversify due to natural selection.When the author refers to the Song of the Cell, he refers to the inter-connectedness -both internal and external to the cell. But when we visualize the whole nature endowed with plants and animals composed of billions in harmonious ensemble,their communication is not just a song any more,but an eternal symphony!
