Signal gradients in 3-D guide stem cell behavior
Phys.Org In their first test, the researchers found that stem cells changed into cartilage or bone cells in the directions of two opposing soluble growth factor gradients: one that promotes cartilage, called TGF-beta 1, and another that promotes bone, called BMP-2. |
