Fig. 1From: Generation of functional dopaminergic neurons from human spermatogonial stem cells to rescue parkinsonian phenotypesMorphological and biochemical features of primary hSSCs. Phase-contrast microscopy showed the morphology of the enzymatically dissociated cells (a) and purified hSSCs for 3, 5, and 7 days, respectively (b–d). e, f Immunofluorescence revealed the expression of GPR125, DAZL, and GFRα1 in primary hSSCs.
