UC-MSCs overexpressing hepatocyte growth factor (HGF) could differentiate into dopaminergic neuron-like cells secreting dopamine, tyrosine hydroxylase, and dopamine transporter [78] and promoted nerve fiber remyelination and axonal regeneration one week after transplantation in rats with collagenase-induced intracerebral hemorrhage [30]. Here, HGF is linked to intracerebral hemorrhage.
