GFAP and neurodegenerative disease: We identified that hUCB contained not only hematopoietic stem cells (HSC) but also mesenchymal stem cells (MSC) which expressed neural makers such as Tuj1, TrkA, glial fibrillary acidic protein (GFAP) and cyclic nucleotide phosphodiesterases (CNPases) facilitating a therapeutic approach for neurodegenerative diseases [5].
