Compared with wild-type (WT) spheres, the size of N2ICD-expressing spheres was significantly increased, whereas the size of MAML1dn-expressing spheres was significantly decreased (WT, 56±1.7 μm, n=90 spheres; N2ICD, 111±2.4 μm, n=215; MAML1dn, 41±0.5 μm, n=291; mean diameter ±S.E.M., P<0.0001; Figures 5a and b).
This sinister philosophical parable points to questions whose answers lie still in the sphere of wild speculation: Given the fact that chimpanzees (Pan troglodytes) and modern humans (Homo sapiens) share ninety-six per cent of the same genes, how did it actually happen?
Total RNA was isolated from sphere stage wild type and MZ eomesa embryos using Trizol (Invitrogen) according to the manufacturer's instructions.
We tested the effectiveness of the drug by treating wild-type embryos from sphere stage to 24 hpf with 100 µM DAPT and, as expected, we phenocopied the mind bomb (mib) mutant, which lacks a ubiquitin ligase that is essential for Notch signaling [26].
Genes differentially expressed (P ≤0.05) between wild-type and MZeomesa sphere stage embryos in the RNA-seq experiment.
Progenitor Cell Polarization upon LPA Stimulation, Related to Figures 2 and S2 Time-lapse movie showing (I) polarization of progenitor cells obtained from wild-type embryos at sphere stage (4 hpf) and cultured in suspension in the presence of 100 μM LPA.
Blastoderm cells of donor embryos were exposed to UV for 30 second to un-cage the Q-Rhodamine and then transplanted into wild type host embryos at sphere stage as described previously [82].
It has been reported that wild-type embryos treated from sphere stage (4.3 hpf) with DAPT display somitic and neuronal defects that are typical of Notch-depleted embryos [25].
When asked who Reich viewed as competition in the Wild Wild West of the payments sphere, he said, "The reality is that our closest competition are the top four banks.
Moreover, these levels were comparable to the sphere forming potential of wild type neocortex.
