How scaffold and biomaterials help regeneration

After the discovery of stem cells, we started isolating them and culturing them in the lab to make thousands and millions of them. One treatment is to directly inject those stem cells to the site of injury, which we call free cell transplantation. But it doesn't a very efficient treatment. Because most of the stem cells that we are going to inject are going to be lost during the procedure. Moreover, many of them don't know what they should do after that. To overcome this, we make a temporary structure called a “scaffold“ to support the stem cells. It provides physical and chemical cues for our stem cells to proliferate and differentiate into more specified cells. Therefore, the properties of the scaffold are crucial. So, in this video, I will explain some of those properties. ___________________________________________________________ In this channel I'm using a number system for my references, which you can see the number in the left corner of my video.
