26],[27] Although some researchers recently showed that extracts of plants in the family Umbelliferae including Oenanthe javanica and Angelica sinensis improved cell proliferation and neuroblast differentiation in the SGZ of the hippocampal DG,[28],[29] neurogenic effects of GLein the brainhave not yet been investigated.

More sophisticated and less destructive methods were slowly developed and in 1942, Carlson studied embryonic neuroblasts of Chortophaga (Carlson 1942), perforating living cells with a microneedle to manipulate the spindle and associated chromosomes; he determined that the latter were mechanically attached to the spindle, which was a semisolid longitudinal structure, through their kinetochores from prophase through late anaphase.
