Proliferation of brown adipose tissue-derived cells in OGR1 KO mice in the mixed background.

<p>(A) SPC stimulated proliferation was not significantly different in BAT from FL <i>vs.</i> KO mice. SPC (2.5 µM) or LPC (2.5 µM) was used. (B) The effect of pH on proliferation was not significantly different in FL <i>vs.</i> KO. The results in this figure are representative of at least 3 independent experiments. * represents a <i>P</i> value of <0.05.
