BioRevolution #10 - Organoids

BioRevolution #10 - Organoids

Before diving into more discussions on organoids, I realized that it’s crucial to first address the concept of organoids itself. Recently, while talking about Organoid Intelligence, a member of the audience asked, "What exactly is an organoid?" This question illuminated the need to clarify this concept for everyone, not just those within the scientific community. As someone deeply motivated to make science accessible beyond the realm of scientists, it felt strange to have overlooked such a fundamental point.

My BSc. graduation thesis was almost entirely related to this topic, and I began with a similar introduction… In a world where everything has become so personalized, where social media platforms use advanced personalization, it was inevitable that healthcare would also move away from a one-size-fits-all approach. In an environment where personal outcomes are expected, the processes themselves must also be tailored to the individual. So, when we think of personalized treatment and its associated processes, what comes to mind? Naturally, the answer is organoids, the very subject of our discussion. By creating organoids from a patient's own cell sources, a unique, patient-specific treatment process is designed. This truly represents a revolutionary shift in the field of healthcare.

Today, we’re delving into the topic of organoids. This won’t be our first or last conversation about organoids, so I encourage you to read carefully and take in this fascinating subject.


Scientific Perspective

An organoid is essentially a laboratory-grown, three-dimensional, miniaturized version of an organ. These structures are derived from stem cells or differentiated cells and possess the ability to self-organize and renew themselves. Organoids contain multiple cell types found in an organ and mimic some of the key features of real organs, such as their cell composition and basic functions. Typically, they arise through the spontaneous self-organization of their constituent cells, although in certain cases, specific hormonal or growth factor signals are introduced to direct the differentiation of very immature stem cells. [...] Organoids serve as simplified, tissue-engineered in vitro models that can replicate the complex structure and function of tissues. They are developed in three dimensions, meaning they have a more realistic structure compared to traditional flat cell cultures.

Creating an organoid involves a fascinating process that starts with sourcing the right cells, which can be stem cells like embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), or even somatic stem cells. These cells are remarkable because they have the potential to become various types of specialized cells found in our organs. To initiate organoid formation, scientists first obtain these cells through a process of mechanical or enzymatic dissociation, where tissues from organs or previously preserved organoids are carefully broken down into smaller fragments or individual cells.

Once the cells are isolated, they are placed in a special culture medium that encourages them to group together, forming small 3D clusters known as spheroids. These spheroids are the building blocks of organoids and can be created using different methods, including suspension cultures, bioreactors, or even roller bottles. After spheroid formation, they are transferred into a gel-like substance, such as extracellular matrix (ECM) or matrigel, which provides a supportive environment that mimics the natural surroundings of cells in the body. The choice of medium and the specific growth factors added to it are tailored to the type of organoid being created, whether it's for the stomach, liver, or even a tumor model. Over time, with careful nurturing, these spheroids develop into fully grown organoids that closely resemble their in vivo counterparts, offering a powerful tool for research into human biology and disease. This entire process can take several weeks to months. [...]

Organoids are powerful tools used in scientific research to better understand human biology and disease. They serve as miniature models of real organs, allowing researchers to study how organs develop, function, and respond to various treatments in a controlled laboratory environment. Because organoids can mimic the complexity of human tissues, they are especially valuable for studying diseases, testing new drugs, and even exploring personalized medicine approaches, where treatments can be tailored to the specific needs of individual patients. Additionally, organoids offer a promising alternative to animal testing, providing more accurate human-relevant data while reducing the need for animal models in research.

Future Perspective

I will present to you two scenarios, two imaginative journeys into the future perspective.

  • Let's fast forward to a time when organoids are readily available and imagine how your experience as a patient might unfold.

You walk into the doctor’s office and describe your symptoms—symptoms that you’ve never experienced before. The doctor reviews your digital twin, a virtual model of your body that tracks your health in real-time. However, this particular symptom originates from a part of your body that isn’t monitored by a biosensor, and there’s no record of past issues in this area. Imaging techniques are employed, and a tumor is detected. Your doctor updates your digital twin with this new information, and the process of gathering a sample begins.

A biopsy is taken from the tumor, and organoid research is initiated. Scientists create a miniaturized version of your tumor—an organoid—that mimics its behavior. Through this organoid, disease modeling is conducted, and the resulting data is integrated into your digital twin. This allows your digital twin to reflect the progression of the disease accurately. Multiple treatment scenarios are then tested, and the five most promising drugs are identified. Next, these drugs are tested on the organoid, and the most effective one is selected for your treatment. Meanwhile, a biosensor tailored to your condition is installed, enabling comprehensive, real-time monitoring of the disease.

As you discuss these developments with your doctor, your digital twin offers insights into potential future illnesses, providing preventive healthcare recommendations. The biggest question lingering in your mind, however, is, "How could this disease have been prevented?"

Even in a world equipped with advanced technology that makes us feel secure, people of that time will be pondering new challenges. "How was this not prevented?" We are always on the frontier of the most advanced systems, yet we still find ourselves questioning and striving for something more.


  • Imagine a future where the concept of organoids has advanced to the point where we can create entire organs from scratch. Now, let's delve into a thought experiment: If we were to construct all the organs of a person using organoids, would that be considered cloning?

You step into the lab, where scientists have successfully grown a complete set of human organs from organoids. The organs are perfectly functional, each one crafted to replicate the exact characteristics of a real human body. But here's the intriguing question: If we assembled these organs into a full body, would this creation be a clone?

The next step in this scenario is even more mind-bending—could this body, made entirely from organoids, actually be brought to life? The notion of animating a body grown from organoids leads to a cascade of questions about identity and existence. Would this being, this organoid "clone," begin its existence with the knowledge and experiences that you possess, or would it start from a blank slate, learning and growing just like any other human being?

Now, consider your feelings towards this creation. Would you feel a sense of envy toward this being, made to mirror your physical form, yet unburdened by your past? The idea of an organoid clone living a life parallel to yours, with the potential to carve out its own unique path, raises profound questions about self-identity and the nature of life itself.

As we ponder these possibilities, it's clear that even in a world of incredible technological advancements, we would continue to wrestle with the implications of what it means to create life, to replicate our own existence, and to confront the emotions that arise from such groundbreaking developments. Would you embrace this new form of life, or would you find yourself questioning its place in the world—and your own?
