NGFR and Alzheimer disease: In patient (b), not only were ANGPT1 levels significantly higher in CD271+ AD-MSCs with AT (313.4 ± 18.9 pg/ml) compared to CD271− AD-MSCs with AT (208.1 ± 7.2 pg/ml, p = 0.0002) and AT alone (176.7 ± 10.1 pg/ml, p < 0.0001), but CD271+ AD-MSCs grown in the absence of AT also produced higher levels of ANGPT1 than CD271− AD-MSCs grown in the absence of AT (258.3 ± 11.0 pg/ml compared to 184.6 ± 6.0 pg/ml, p = 0.0037).
