Isolating Stem Cells from Soft Musculoskeletal Tissues
Summary
Isolating adult stem cells from musculoskeletal soft tissues based on the cell’s adherence speed to flask.
Abstract
Protocol
Discussion
It has been recognized that some adult tissues contain multiple stem cells. Over the past few years of study, stem cells have been detected in the soft musculoskeletal tissues, including skeletal muscle and tendon. This current protocol details a procedure, known as the modified preplate technique, that has been successfully used in our laboratory to isolate adult stem cells from tendons and skeletal muscle. Using the modified preplate technique described above the cells can be divided into several populations based on t…
