NGFR and Alzheimer disease: This is comparable to other groups who have achieved similar high purities with MACS: Zhang et al. (2015) produced Kupffer cells of purity 95.7% from mouse livers, after a double MACS sort for F4/80+ and CD11c− cells, and Quirici et al. produced a CD271+ population from human AD-MSCs with 88.5% purity by MACS sorting [14, 22].
