Figure 1 Retention of tritiated thymidine in human umbilical cord matrix stem cells in vitro. Human umbilical cord matrix stem cells were radiolabeled by incubating 1 × 106 cells with 1 μCi tritiated thymidine for 24 h followed by washing with 1 × PBS and kept in the growth medium without tritiated thymidine. Retention of radioactivity was measured on days 1, 3, 7 and 10 post-labeling.
