Guided self-organization and cortical plate formation in human brain organoids
Open accessAbstract
Three-dimensional cell culture models have either relied on the self-organizing properties of mammalian cells or used bioengineered constructs to arrange cells in an organ-like configuration. 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.

Brain organoids derived from iPSCs develop in culture along a trajectory mimicking key features of fetal brain development and can be patterned toward specific brain regions affected in tauopathy.
“Brain organoids derived from iPSCs develop in culture along a trajectory mimicking key features of fetal brain development and can be patterned toward specific brain regions affected in tauopathy (Camp et al., 2015; Lancaster et al., 2017; Paşca et al., 2015; Velasco et al., 2019; Yoon et al., 2019).”
From ELAVL4, splicing, and glutamatergic dysfunction precede neuron loss in MAPT mutation cerebral organoids (2021) · cites this paper as Lancaster et al., 2017
The Online Methods (Preparation of EBs and enCORs) include an iPS cell line, and the main text reports that engineered organoids form forebrain tissue, including regions consistent with hippocampal identity. It also finds that 60-day organoids most closely match early-gestation human forebrain gene expression. The copy does not establish a developmental trajectory matching fetal brain development or connect the patterned regions to tauopathy. (LLM, conf=0.86)
Experimental — accuracy not yet measuredThe advantages of the scaffold primarily stem from the increased surface-to-volume ratio.
“These advantages primarily stem from the increased surface-to-volume ratio, aligning with previous studies that used fibers to guide organoid development and improve surface-to-volume dynamics (68).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
