TAGLN and Alzheimer disease: Regarding the variability of TAGLN expression between MSCs derived from different tissues, this correlates with the intrinsic heterogeneity of MSCs of different tissue origins (such as bone marrow, adipose tissue, cord blood, etc.)[30], as is clearly reflected in the last figure presented here (Figure 7), where we show the expression of nine genes in two types of MSCs: BM-MSCs and AD-MSCs.
