MSC cell viability after long-term expansion in synthetic media.

Media	Week 1	Week 2	Week 3	Week 4
FBS	73	91	90	87
StemMACS	73	86	74	85
HPL	73	91	90	89
PLT Max	68	92	77	91

MSCs were plated for one week in FBS-containing medium after adipose tissue digestion as described, harvested, and then re-plated in each of the synthetic media. The cells were harvested, and viability was determined at the end of each subsequent week. The data are presented as the percent viable cells obtained in three independent experiments.
