Guided self-organization and cortical plate formation in human brain organoids

A Publisher Correction to this article was published on 01 October 2018

This article has been updated


Three-dimensional cell culture models have either relied on the self-organizing properties of mammalian cells1,2,3,4,5,6 or used bioengineered constructs to arrange cells in an organ-like configuration7,8. While self-organizing organoids excel at recapitulating early developmental events, bioengineered constructs reproducibly generate desired tissue architectures. Here, we combine these two approaches to reproducibly generate human forebrain tissue while maintaining its self-organizing capacity. We use poly(lactide-co-glycolide) copolymer (PLGA) fiber microfilaments as a floating scaffold to generate elongated embryoid bodies. Microfilament-engineered cerebral organoids (enCORs) display enhanced neuroectoderm formation and improved cortical development. Furthermore, reconstitution of the basement membrane leads to characteristic cortical tissue architecture, including formation of a polarized cortical plate and radial units. Thus, enCORs model the distinctive radial organization of the cerebral cortex and allow for the study of neuronal migration. Our data demonstrate that combining 3D cell culture with bioengineering can increase reproducibility and improve tissue architecture.

Bright field images of various sized day 10 spherical H9 EBs made with the indicated cell numbers. Note the increase in optically clear neuroectodermal tissue (arrows) relative to the rest of the EB, but the decreased total amount of such tissue in the smaller EBs. e. Immunohistochemical staining of day 10 H9 EBs of varying sizes for the germ layer markers Brachyury for mesoderm, N-Cadherin for neural ectoderm, Sox17 for endoderm, and E-Cadherin for non-neural epithelium.

Boxed regions are shown at higher magnification below panels. d. Quantification of fluorescence staining of the above markers (mean grey value relative to DAPI). Mean values shown ± SD. n = 6 spheroids (day 30, H9) for each condition. e. Representative images of stained sections of day 40 H9 organoids used for quantification shown in Figure 2c. Individual lobes can be recognized as radially oriented, polarized neuroepithelium surrounding a fluid filled ventricle. Serial sections were stained for the indicated markers. Forebrain tissues (white arrows) are Foxg1+ and exhibit fainter Otx2 signal, midbrain tissues (white arrowheads) exhibit strong immunoreactivity for Otx2 and lack other markers, and cerebellar tissue (yellow arrowhead) exhibits staining for both Otx2 and En2, while En2 single positive regions are hindbrain. Foxg1+ regions showing strong Pax6 staining are dorsal forebrain. However, Pax6 also stains other regions such as that marked by the yellow arrow, which is likely spinal chord, as it does not exhibit staining for the other markers. f. Staining for the ventral forebrain marker Gsh2 and the dorsal marker Tbr2 in H9 enCORs at day 40 reveals the presence of both regions of the forebrain. Note that Gsh2 staining on the ventricular surface is nonspecific. g. Staining for the marker of choroid plexus TTR reveals the presence of this region in H9 40-day enCORs h. Staining for the marker of hippocampus Prox1 reveals the presence of this tissue in H9 40-day enCORs. Scale bars: 500 μm in a., b., c., e., 100 μm in f., g., h.

Side-by-side comparison of CP (arrowheads, brackets) in 60-day H9, 60-day iPSC, and 70-day H1 organoids stained by H&E. d. H&E staining of 60-day H9 enCORs with dissolved Matrigel show a dense band consistent with CP, whereas enCORs instead treated from day 30 with the matrix metalloprotease inhibitor GM6001 show no signs of CP formation. e. H&E staining of 60-day H9 enCORs with dissolved Matrigel compared with dissolved laminin, dissolved laminin/entactin complex, or a mixture of laminin/entactin and collagen I. Note the presence of a dense CP band with Matrigel, while laminin alone or in combination with entactin and collagen I display no clear CP and only occasionally a faint band of cells with laminin/entactin. Scale bars: 200 μm in a., 100 μm in b., c., d., e.

Supplementary Figure 9 Comparison of enCOR method with other 3D organoid methods

a. H&E staining of H9 enCOR, H9 cortical spheroid generated according to Pasca et al. and iPSC SFEBq organoids generated according to Kadoshima et al. SFEBq 1 and 2 were generated in independent laboratories, with SFEBq 1 generated in the Lancaster laboratory and SFEBq 2 generated according to Otani et al. in the Livesey laboratory. All are shown at 60-days of development and at the same magnification. Note the dense CP band (black arrowheads) with the enCOR method and the overall larger size as well as presence of larger lobules surrounding fluid-filled ventricle-like spaces. While the other methods show ventricular zone regions (yellow arrowheads), such a dense organized CP is not visible. Lower panels are higher magnifications of the boxed regions. b. Immunofluorescent staining similarly reveals a Ctip2+ CP (bracket) surrounded by Map2 staining in an iPSC enCOR while other methods do not display this architecture. Laminin staining is detected as expected in enCORs and SFEBq organoids where it can be seen in some SFEBq organoids coating the external surface (white arrowheads) with adjacent formation of a thin band of cells reminiscent of a rudimentary CP (yellow asterisk). c. Staining for neuronal subtypes in developing CP in H9 enCORs at two time points reveals the progressive separation of upper layer (Satb2+ and Cux2+) which labels a broad population, and deep layer (Ctip2+) neurons which label neurons in deeper regions of the CP. Note the progressive thickening of the radially organized CP, and the evident layers exhibiting transitioning organization of neuronal processes (Map2 staining). Scale bars: 500 μm in a. upper panel, 250 μm in a. lower panel, 100 μm and b., c.

Supplementary Figure 10 Slice culture and live imaging in enCORs enables visualization of neuronal migration and activity.

a. Nestin staining reveals basal processes (arrowheads) with end feet that terminate at the laminin positive basement membrane (arrows) in a 60-day H9 enCOR. b. Nestin staining in 60-day H9 spheroid reveals the presence of radial glial processes that show disorganization outside the ventricular zone (arrowheads) and terminal end feet within the tissue (arrows). c. Frames from live imaging of a GFP electroporated neuron (Supplementary Video 3) showing the dynamic multipolar phase of migration with multiple transient processes (arrowheads) extending from the main cell body (arrow). Time stamp is hours:minutes. d. Frames from live imaging of a putative tangentially migrating interneuron (Supplementary Video 6). Note the presence of two leading processes, which the cell body alternates between. Before the nucleus (arrow) enters the leading process, a small accumulation can be seen (arrowhead) consistent with the antecedent movement of the centrosome, a behavior observed in vivo (Higginbotham, H. R. & Gleeson, J. G. The centrosome in neuronal development. Trends in Neurosciences 30, 276–283 (2007)). e. A false color heatmap frame of live imaging with the calcium dye Fluo-4 (Supplementary Video 7) and single cell tracings of the indicated cells, labeled regions of interest (ROI), as measured by change in relative fluorescence (ΔF/F = (mean grey value - minimum grey value)/minimum grey value) showing spontaneous calcium surges. Scale bars: 100 μm in a. and b., 20 μm in c., 50 μm in d., e.
