Fig. 5From: Low-dose strontium stimulates osteogenesis but high-dose doses cause apoptosis in human adipose-derived stem cells via regulation of the ERK1/2 signaling pathway a Morphological features of hASCs exposed to SrRan at different time points. b hASCs were treated with SrRan (1000 μM) in GM and OM at the indicated days and viability was measured with a CCK-8 assay.
