The UW researchers zeroed in on two related Wnt receptors on the cell surface--LRP5 and LRP6 ... On the other hand, LRP5 is clearly necessary for mammary stem cells to work ...

"Our hypothesis was that different Wnt ligands activate the Wnt pathway by preferentially signaling through either LRP5 or LRP6," Alexander says....(size: 4.5Kb)
