Fig. 2From: The legacy effects of electromagnetic fields on bone marrow mesenchymal stem cell self-renewal and multiple differentiation potentialLasting effects of EMF on BMSC proliferation. a BMSCs with or without EMF pretreatment were seeded in 96-well plates, and proliferation of both groups detected from day 0 to day 6 (n = 3). b Representative gross observation of colony-forming unit formation of both groups after 7 days of culture. c Colonies containing more than 50 cells counted, and colony-forming unit ratio acquired by colony number/400 (n = 3). Data shown as mean ± SD. *P < 0.05, **P < 0.01. EMF electromagnetic fields, OD optical densityBack to article page
