Researchers can make organoids from anyone. This lets them study how different tissues work. The American Society for Cell Biology sees the value in this field. They’ve set rules to make stem cell research more reliable.

Even though organoids are a great alternative to animal models, we must remember their limits. They can only mimic certain organ functions.

This section is your introduction to the world of organoids. It prepares you for a deep dive into their science, uses, and ethics in medical research.

Understanding Organoids

Organoids are three-dimensional (3D) structures made from stem cells. They look and work like real organs. This makes them key for research.

They have special characteristics of organoids. These include being self-organized, complex, and closely related to human biology.

Created through 3D cell culture, organoids have many cell types like real organs. Scientists use them to study how cells work together. This helps them understand health and disease better.

Organoids are like mini versions of organs. They let scientists test new treatments in a real-like setting. This is very useful for finding new ways to help people.

How to make organoids can differ, but the aim is the same. For example, making intestinal organoids uses special growth factors. These help stem cells turn into the different cells of the intestine.

The Science Behind Organoid Creation

Creating organoids begins with stem cell differentiation. Here, stem cells can turn into many different cell types. They need specific signals and conditions to form organoid structures.

These structures mimic how organs develop naturally. This helps us understand what’s important for organ growth.

Organoid culture techniques have improved a lot. Early methods used gels or scaffolds. Now, we use hanging droplets or magnetic levitation.

The air-liquid interface (ALI) method started around 2012. It lets us create organoids from many cell types. This method helps cells differentiate better.

Using 3D organoid systems is key. They mimic the real arrangement of cells in tissues. This makes research more accurate.

Scientists can now make organoids in different ways. They use special media and growth factors like EGF. This helps grow specific types of organoids.

It takes 30 to 60 days for organoids to fully grow. They need special medium that’s changed twice a week. Some organoids can live up to 100 days, or even a year, with the right care.

Types of Human Organoids

Human organoids are a big step forward in medical research. They help us study different human organs and diseases. These models come from many organs, like the lung, stomach, and brain.

Creating organoids starts with stem cells or tissue from donors. This method makes complex tissues that act like real organs. For example, intestinal organoids grow into a full 3D structure after a few weeks.

Each organoid has different cell types from various layers. But, some important cells like blood vessels or immune cells might be missing. This shows we need new ways to make these models better.

Studies show liver organoids from stem cells are like fetal liver cells, not adult liver. Brain organoids also act like fetal brain cells. This is great for studying brain development.

Adding missing cells or germs to organoids makes them more like real organs. This helps us understand human systems better. But, making sure all organoids are the same is still a big challenge.

Applications of Organoids in Research

Organoids are changing the game in biomedical research. They offer a new way to study human diseases and find new treatments. Their ability to mimic real human tissues is a big plus over old methods.

Old studies use 2D cancer cell lines and animal models. But these don’t fully capture the real biology of tumors. Organoids, with their self-renewal and ability to grow into different types of cells, are a better choice. They can be grown for a long time and can be genetically changed like 2D cells.

There are two main ways to make organoids: submerged cultures and air-liquid interface (ALI) cultures. ALI cultures help grow organoids that look and work like real tissues. This is great for studying diseases like those in the gut.

New ways to make organoids have made them better. For example, using ROCK inhibitors helps them grow faster and live longer. Patient-derived organoids (PDOs) are very good at predicting how well drugs will work, helping with personalized medicine.

Organoids are also a big help in finding new drugs. Tumor-derived organoids, or tumoroids, make it easier to test drugs. This leads to better drug discoveries, about 30% better than before. Adding single-cell sequencing and genome editing to organoid research makes models even more accurate, with a 90% success rate.

Organoids are not just for cancer research. They are also used in genetics and studying infectious diseases. They can come from normal or cancerous tissues, making them very versatile. As the organoid market is expected to grow to over $5 billion by 2028, their role in science is set to grow even more.
