DPSC secretome treatment preserves morphology and improves the viability of SH-SY5Y cells exposed to Aβ _1–42. (a–c) Phase contrast micrographs of SH-SY5Y cells exposed to Aβ _1–42 only, Aβ _1–42, and DPSC secretome or nonexposed as control (full-size images are presented in Supplementary Figure S1). (d) Cell viability as detected at 450 nm absorbance (mean ± SE, n = 3. ^∗ p < 0.05, ^∗∗ p < 0.01).
