In The Song of the Cell (2022), physician and biologist Siddhartha Mukherjee explores cell biology: its history as a field of study, how it transformed medicine, and new practices that could help to eliminate cancer and other diseases. He also considers the prospect of cellular or genetic engineering, both in the treatment of illnesses and the possibility of creating “new humans” for whom hereditary diseases are a thing of the past. The book builds on his previous works on the history of cancer and DNA to explain the science of cells to the lay reader.
An Indian-American who completed his education at Stanford, Harvard, and Oxford, Mukherjee is a professor of medicine at New York’s Columbia University. In addition to publishing his research in medical journals, he frequently writes for publications such as The New Yorker, The New York Times, and Vice about cellular therapy, genetics, the Covid-19 pandemic, the medical uses of artificial intelligence, and the emotional turmoil physicians face. His most acclaimed book, The Emperor of All Maladies, won the 2011 Pulitzer Prize, and much of that book’s subject matter is revisited in The Song of the Cell.

Here's a preview of the rest of Shortform's The Song of the Cell summary:
Mukherjee begins with an overview of cell biology, including the history of the field since the 19th century, the general characteristics of human cells, and cellular processes like energy production and reproduction through cellular division.
Mukherjee argues that the discovery of cells revolutionized medicine, complicating previous theories of disease that attributed bodily illness to an imbalance of fluids like blood and phlegm, poor air quality, or mental health issues. The discovery that cells, like all living beings, are born from a parent of the same type also complicated popular understandings of reproduction.
(Shortform note: When discussing illnesses related to an imbalance of fluids, Mukherjee is describing humorism, a dominant medical belief throughout the known world from the time of ancient Greece through the 17th and 18th centuries. The most infamous treatment associated with humorism is bloodletting, or depriving the patient of “bad blood” by cutting into veins or applying leeches—which...
Moving beyond his descriptions of cells, Mukherjee considers how new practices like cellular therapy and cellular engineering can advance medicine. He’s particularly interested in the prospect of manipulating cells to cure cancer, eliminate disease, and even alter the human genome—though he acknowledges how little is still known, the potential to do harm, and the ethical considerations. Above all, he emphasizes that nothing in the body works in isolation. Cells are constantly communicating with one another, and while this enables many of the body’s most complex and impressive functions, it also means that any disruption to the system could have unexpected consequences.
Mukherjee refers back to 19th-century descriptions of cells as a kind of community, able to function independently but constantly working in tandem to reproduce, exchange chemicals and proteins, and enable the body’s more complex processes. Cells work together not only within an organ or system, but across the body as a whole. For example, the circulation of blood involves not just blood cells but those of the heart, the lungs, the bones, the pancreas ,...
This is the best summary of How to Win Friends and Influence People I've ever read. The way you explained the ideas and connected them to other books was amazing.
Mukherjee argues that cells are fundamental to our understanding of the human body, health, and medicine. He also suggests that our knowledge of cells and of the relationship between cells and genes will radically transform the future of medicine and even human reproduction.
How have cells or genes played a role in your life and your relationship with medicine? Were you always conscious of this relationship?
