Fig. 4From: 940 nm diode laser induced differentiation of human adipose derived stem cells to temporomandibular joint disc cellsCellular ATP proliferation assessed at 24, 48 and 72 h: and 1-week and 2,3 weeks post-irradiation with 940 nm diode laser. The ATP proliferation was evident in all experimental groups. The importance of bFGF and laser in cell proliferation and an increase in ATP is clearly reflected. A significant increase in ATP compared to cells in other groups is evident at LB72 h. The statistical significance is presented as *p < 0.05Back to article page
