"A variety of marine worms": plate from Das Meer by M. J. Schleiden (1804–1881)

[zerogate]

Over a hundred and fifty years ago, the German botanist Matthius Schleiden was pondering the recently discovered fact that organisms as simple as water fleas and as complex as human beings are made up of individual cells. Each of those cells has all the apparatus necessary to lead a life of its own. It is walled off in its own miniworld by a surrounding hedge of membrane, carries its own metabolic power plants, and seems quite capable of going about its own business ruggedly declaring its independence. Yet the individual cells, in pursuing their own goals, cooperate to create an entity much larger than themselves. Schleiden declared that each cell has an individual existence and that the life of an organism comes from the way in which the cells work together.

In 1858, pathologist Rudolph Virchow took Schleiden’s observation a step further. He declared that “the composition of the major organism, the so-called individual, must be likened to a kind of social arrangement or society, in which a number of separate existencies are dependent upon one another, in such a way, however, that each element possesses its own peculiar activity and carries out its own task by its own powers.” A creature like you and me, said Virchow, is actually a society of separate cells.

Another creature enlisted in a superorganism is the citizen of a society called the sponge. To you and me, a sponge is quite clearly a single clump of squeezable stuff. But that singularity is an illusion. Take a living sponge, run it through a sieve into a bucket, and the sponge breaks up into a muddy liquid that clouds the water into which it falls. That cloud is a mob of self-sufficient cells, wrenched from their comfortably settled life between familiar neighbors and set adrift in a chaotic world. Each of those cells has theoretically got everything it takes to handle life on its own; but something inside the newly liberated sponge cell tells it, “You either live in a group or you cannot live at all.” The microbeasts search frantically for their old companions, then labor to reconstruct the social system that bound them together. Within a few hours, the water in your bucket grows clear, and sitting at the bottom is a complete, reconstituted sponge.

Remove the sponge cell from the sponge, prevent it from finding its way back to its brethren, and it dies. Scrape a liver cell from the liver, and in its isolation it too will shrivel and give up life. But what happens if you remove a human from his social bonds, wrenching him from the superorganism of which he is a part?

In the 1940s, the psychologist Rene Spitz studied human babies isolated from their mothers. These were the infants of women too poor to care for their children, infants who had been placed permanently in a foundling home. There, the children were kept in what Spitz called “solitary confinement,” placed in cribs with sheets hung from the sides so that the only thing the babies could see was the ceiling. Nurses seldom looked in on them more than a few times a day. And even when feeding time came, the babies were left alone with just the companionship of a bottle.

Hygiene in the homes was impeccable, but without being held, loved, and woven into the fabric of a social web, the babies could not maintain their resistance. Thirty-four out of ninety-one died. In other foundling homes, the death rate was even higher. In some, it climbed to a devastating 90 percent. A host of other studies have shown the same thing: babies can be given food, shelter, warmth, and hygiene, but if they are not held and stroked, they have an abnormal tendency to die.

A Journey Through the History of Cells

A world smaller than a raindrop, yet bustling with activity like a miniature city. Welcome to the incredible universe of the cell, the fundamental unit of life! The cell might seem microscopic, but its history stretches back eons and holds stories as vast as the galaxies. Today, we embark on a voyage through time, delving into the fascinating discoveries that shaped our understanding of these minuscule marvels.

The First Glimpse: Unveiling the "Cells", Our journey begins in 1665, where Robert Hooke, wielding an early compound microscope, peered into the intricate world of cork. He observed box-like structures, resembling the rooms monks inhabited, and christened them "cells." While he couldn't fathom their true nature, Hooke had opened a window into a hidden universe.

From Cork to Critters: Expanding the Cellular Realm: Another pioneer, Antonie van Leeuwenhoek, soon pushed the boundaries further. His improved microscopes unveiled a teeming microcosm of single-celled organisms, like the "animalcules" (protozoa) he described in 1674. This marked the realization that life existed beyond visible forms, its very foundation laid in these intricate units.

The Cell Theory Takes Shape: Unifying Principles Emerge: Fast forward to the 19th century, where the stage was set for a defining moment. Matthias Schleiden and Theodor Schwann, inspired by countless observations, proposed the cell theory in 1839. This groundbreaking concept established three fundamental principles:All living organisms are composed of one or more cells. The cell is the fundamental unit of structure and function in living organisms. All cells arise from pre-existing cells.

This unifying theory laid the cornerstone for modern cell biology, revolutionizing our understanding of life.

With the cell theory established, curiosity shifted inwards. The nucleus, discovered by Robert Brown in 1833, became the focus. Further advancements in microscopy revealed a bustling metropolis within each cell, teeming with specialized structures called organelles, each with its unique function. The 20th century saw a whirlwind of discoveries. Rudolf Virchow solidified the third tenet of the cell theory with his famous dictum, "omnis cellula e cellula" (all cells come from cells), while Louis Pasteur challenged spontaneous generation, further solidifying the cell's central role.

The human body has trillions of cells, more than all the stars in our Milky Way galaxy and you're constantly replacing cells shedding about 30,000 skin cells every minute!! You're a bustling metropolis of trillions of tiny workers, all working together to keep you going. The knowledge gained from countless studies of cells propelled medical breakthroughs. The identification of chromosomes and genes within cells paved the way for genetics, opening doors to understanding diseases and developing treatments. Cell therapies and regenerative medicine offer glimpses into a future where damaged cells can be repaired or replaced. As we stand at the threshold of the 21st century, the exploration of cells continues. Advanced microscopes like electron microscopes and confocal laser scanning microscopes offer unprecedented views into the cellular world. CRISPR technology allows us to edit genes within cells, holding immense potential for treating genetic diseases.

As we delve deeper, the mysteries of the cell unfold, revealing its adaptability, complexity, and beauty. This tiny titan, once just a glimpse through a primitive lens, holds the key to understanding life itself. The journey through the history of cells is a testament to human curiosity and ingenuity, and it's a journey that continues, offering endless possibilities for the future.
