Abstract

The functional and molecular similarities and distinctions between human and murine astrocytes are poorly understood. Here, we report the development of an immunopanning method to acutely purify astrocytes from fetal, juvenile, and adult human brains and to maintain these cells in serum-free cultures. We found that human astrocytes have abilities similar to those of murine astrocytes in promoting neuronal survival, inducing functional synapse formation, and engulfing synaptosomes. In contrast to existing observations in mice, we found that mature human astrocytes respond robustly to glutamate. Next, we performed RNA sequencing of healthy human astrocytes along with astrocytes from epileptic and tumor foci and compared these to human neurons, oligodendrocytes, microglia, and endothelial cells (available at http://www.brainrnaseq.org). With these profiles, we identified novel human-specific astrocyte genes and discovered a transcriptome-wide transformation between astrocyte precursor cells and mature post-mitotic astrocytes. These data represent some of the first cell-type-specific molecular profiles of the healthy and diseased human brain.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cldn5 is an endothelial cell-specific tight junction protein and is enriched in blood vessels.

    “Cldn5 is an endothelial cell-specific tight junction protein (Supplementary Fig. 2D)29, 30, which we confirmed to be enriched in blood vessels using a brain capillary extraction method”

    From Social stress induces neurovascular pathology promoting depression (2017) · cites this paper as [30]

    The Results section on purified human cell transcriptomes identifies CLDN5 as an endothelial cell-specific marker and reports selective expression in endothelial cells. Our copy does not identify CLDN5 as a tight junction protein. The blood-vessel enrichment is presented in the citing sentence as the citing authors’ own confirmation, not a finding attributed to this source. (LLM, conf=0.86)

  • Plexin-B1 is predominantly expressed in astrocytes as compared to other cell types in both mouse and human CNS.

    “a survey of gene expression databases (brainrnaseq.org)31, 32 revealed a predominant expression of Plexin-B1 in astrocytes as compared to other cell types in both mouse and human CNS (Fig. 2A).”
  • Morphological and transcriptomic comparisons have revealed prominent differences between mice and humans.

    “morphological and transcriptomic comparisons have revealed prominent differences between mice and humans101–103”
  • RNA-seq data for MCT8 gene expression in human brain demonstrated similar levels in purified human endothelial cells, astrocytes, and neurons, and to a lesser extent in mature oligodendrocytes, and it was not detected in microglia.

    “Analyzing RNA-seq data for MCT8 gene expression in the human brain (Zhang et al., 2016) demonstrated similar levels in purified human endothelial cells, astrocytes, and neurons, and to a lesser extent in mature oligodendrocytes, and it was not detected in microglia (Figure 3A).”
  • The chr3q28 region proteins showed significant enrichment in neurons.

    “For each of the 208 proteins, we analyzed brain-relevant cell-type expression data34 (Supp. Table S28) to determine cell specificity and observed a significant enrichment in neurons (Fig. 3B, Supp. Fig. 13, Supp. Table S29), supporting relevance of this region for brain-related traits.”

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.
