Abstract
After transplantation, adult bone marrow-derived mesenchymal stem cells (BM-MSCs) may undergo transdifferentiation and/or cell fusion in response to new environments. However, the mechanism(s) that govern these cell fate switches remain unknown. Here we demonstrate that the pathology associated with murine Niemann– Pick disease type C (NP-C) cerebellum augments the ability of BM-MSCs to fuse with Purkinje neurons. The results suggest that the degenerative microenvironment of Purkinje neurons in the NP-C cerebellum modulates the cell fate switch of BM-MSCs via cell fusion.
