Breast cancer is a serious issue. It is one of the most common types of cancer in women. It is known for its ability to spread quickly and aggressively. This is due to a specific type of cell called breast cancer stem cells. These cells are particularly troublesome because they can migrate and invade other parts of the body. This makes it hard to treat and cure. ...
Stem cells are the body's raw materials. They have the remarkable ability to develop into many different cell types. This ability is what makes them so exciting for medical research. One type of stem cell is called adipose-derived stem cells, or ADSCs. These come from fat tissue. They are a type of mesenchymal stem cell, which means they can turn into different ...
In the realm of tissue engineering, scientists are exploring new ways to create living replacements for damaged tissues. These engineered tissues aim to help the body heal itself. However, there are challenges. Custom-made tissues can be expensive and take time to create. Plus, they might not work as well for every patient. One promising approach is to use materials...
Blood stem cells, also known as hematopoietic stem and progenitor cells (HSPCs), are like superheroes in our body. They can transform into different types of blood cells, which is crucial for our immune system and overall health. These cells have two main states: active and resting. The switch between these states is controlled by both the cell itself and its environ...
The world of regenerative medicine is buzzing with excitement over a new player in the game. This player is the Aceman System, a cutting-edge solution that's shaking up the way we produce mesenchymal stem cells (MSCs). MSCs are like the superheroes of regenerative medicine, but making them in large quantities has been a real headache. The Aceman System is here to cha...
Kidney organs made in labs could be a game-changer for people with kidney diseases. Think about it— having a new kidney grown just for you, no waiting lists or ethical dilemmas. This could be the future, but we're not there yet. Scientists are working hard to make these lab-made kidneys work just like the real thing. Current lab-grown kidneys are still pretty ba...
Human mesenchymal stromal cells, or hMSCs, are special adult cells that can turn into different types of cells. They're super important in regenerative medicine. One big concern is that these cells are often grown with supplements that come from animals. Regulatory agencies want us to avoid these animal-based supplements to keep things safe. But finding good, safe su...
Dr. Smith knows that growing new heart tissue in the lab is tricky. One challenge is making sure the tiny scaffolds that support the cells have the right shape. They should mimic the native heart's structure, like the way muscle fibers line up. Recently, Dr. Smith and their team tried something new. They created a 3D-printed scaffold using a flexible plastic called ...
Did you know that our bodies produce tiny molecules called reactive oxygen species (ROS) during normal oxygen metabolism? These molecules can act as messengers, influencing various processes in the body. However, when there are too many ROS, they can cause big problems, especially in the brain and nervous system. Excessive ROS can lead to the death of nerve cells and...
Creating lifelike tissue structures for medical purposes is a big challenge. Scientists are trying out new methods like using self-healing fluids to help in this process. One interesting way is using gellan gum to form little gel balls, called granular gels. These are made by stirring during gel formation. The cool thing about these granular gels is that they work we...
