How Do Stem Cells Work? - Part 4

"How do stem cells work?" is our short format video series to help explain the many functions of how stem cells can help heal. Based on the older basic science research, scientists initially thought that stem cells worked only through differentiation (or transforming into and replacing a damaged cell). However, over the last decade a newer mechanism of stem cell action has been discovered called paracrine signaling. This means that the stem cells act as a general contractor, barking out chemical signals as orders to other cells to assist in the repair effort. So here's my one minute video explanation of that very dense scientific topic!
