What types of cells can you use for bioprinting?
I would say as many cells as there are in the different tissues and organs. Scientist around the world are constantly finding more and more cells so I guess there won't be a definite answer in the near future. What's important to note is that not all cells can be printed with the same bioink. Each cell has a specific function and thus they requires a specific environment. Thus, scientist in the field are developing cell-specific or cell-instructive bioinks to be able to bioprint functional tissue models.
Great question! I think the human body has about 200 different cell types, I wonder how many of these we can currently print with. Since the ear is such a popular structure floating around, I think cartilage cells(chondrocytes) are definitely one of them.
