Abstract
Trypsinization has generally been used as a technique to detach adherent mesenchymal stromal cells (MSC). However, this technique involves chemical manipulation. This study was designed to identify whether detachment of MSC can be induced by cold without using trypsin. MSC isolated from bone marrow were detached via trypsin or exposed to −20°C for 1, 5 or 10 min at all passages. Compared with trypsinization, exposing MSC to −20°C for 10 min resulted in a significant decrease in MSC number and viability. In conclusion, although detachment of adhered MSC on culture dishes via exposure to cold may allow structurally and functionally intact detached cells, the technique requires improvement of the thermotolerance of MSC.
