In general, the complete modified preplate procedure requires 1-2 days of preparation, 1 week of performing the technical procedure, 2-3 days of cell identification with immunocytochemistry, and an additional 2-3 weeks of stem cell population expansion. The equipment required for stem cell culture are similar to that of other cell culture systems which includes a bench-top centrifuge, CO2 incubator, Laminar flow tissue culture hood and an inverted microscope equipped with fluorescence and a digital camera.

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...

isolating stem cells from soft musculoskeletal tissues

Adult stem cells have long been discussed in regards to their application in regenerative medicine. Adult stem cells have generated a great deal of excitement for treating injured and diseased tissues due to their impressive capabilities to undergo multi-lineage cell differentiation and their self-renewal ability. Most importantly, these qualities have made them advantageous for use in autologous cell transplantation therapies. The current protocol will introduce the readers to the modified preplate technique where soft tissues of the musculoskeletal system, e.g. tendon and muscle, are 1st enzymatically dissociated and then placed in collagen coated flasks with medium. The supernatant, which is composed of medium and the remaining floating cells, is serially transferred daily to new flasks. The stem cells are the slowest to adhere to the flasks which is usually takes 5-7 days (serial transfers or preplates) . By using this technique, adult stem cells present in these tissues can be easily harvested through fairly non-invasive procedures.
