Normal mammary fat pads (MFPs) and tumor sections (n = 5 per group) were double-stained for Lyve-1 to identify single M-LECP cells and eight proteins known to promote cell fusion including CD36 [57], CD98 [70], CD209 [71], Dap12 [63], Dc-stamp [63], Sirp-a [72], Sirp-b1 [73], and stabilin-1 [65]. Here, DCSTAMP is linked to neoplasm.
