In this regard, Fábio G. Teixeira et al., using previously generated proteomic databases and mass spectrometry-based analyses, have identified in the hBM-MSCs secretome the presence of several neurotrophic factors and cytokines with important roles and therapeutic actions on PD, including HSP27 (HSPB1) [160]. This evidence concerns the gene HSPB1 and Parkinson disease.
