Dopamine Agonists Affect Ventral Progenitor Cells (A) The olig2 mRNA expressing pMN progenitors are increased in number and labeling intensity after pergolide treatment (24–33 hpf; cross-sections; p < 0.0001). (B) Nkx6.1 labeling is expanded (brackets) after pergolide treatment (24–33 hpf; lateral views; p < 0.0001). (C) A higher proportion of pMN progenitors in M phase (olig2:GFP+/pH3+) is labeled with EdU 2 hr after exposure, indicating shortened G2 phase, after pergolide treatment (24–33 hpf; lateral views; p < 0.05; arrows indicate triple-labeled cells, and arrowhead indicates a cell that is olig2:GFP+/pH3+/EdU-). (D and E) In human embryonic stem cell cultures, driven toward motor neuron differentiation, PCR indicates expression of the d4 receptor at day 16 (D) and the proportion of OLIG2+ cells is significantly (p = 0.0109) increased by NPA at day 16 (E). Error bars represent SEM. Scale bars, 50 μm (A, B, and E) and 20 μm (C). See also Figure S4. |
