Fig. 4. Cell-fate specification activities of patterning and
proneural/inhibitory HLH factors in the population assay. (A-L) The
percentages of neuronal and glial marker-positive cells among total
virus-infected cells are shown (mean±s.d. from four independent
experiments). Viruses used for infection are shown on the x axis.
Dashed horizontal lines indicate the values in the control culture.
