Understanding Scaffolds, Stem Cells, and Growth Factors

Repairing the biology is fundamental to improve the quality of the damaged tissue, making the recovery period more comfortable and shorter. This is done by biological therapies based on three elements; three-dimensional scaffolds, cells and signalling molecules. The main role of three-dimensional scaffolds is to be the support where de cells adhere, they are also bioactive and interact, attract and stimulate those cells. One of the major focuses in regenerative medicine are cell-therapies, that depending on their collection source they have different characteristics. All the biological events basic for the success when regenerating are controlled by signalling molecules. The biological pathways are immediately activated after a tissue injury, using the Growth Factors we are capable of modulate this response. They are involved in biological functions, such as cellular proliferation, cellular survival, migration and even apoptosis.
