  • Publication number: 20250187012
    Abstract: Provided herein is a spatial sampling system that encodes samples with spatial barcodes that identify original spatial position of a microsample within a biological specimen or from different voxels from a biological sample. The method provides cell/nuclei-level resolution of cells and nuclei within microsamples. The method can comprise tagging cells and or nuclei in each microsample or voxel with a first barcode that encodes the original spatial position of the microsample in the biological specimen or the different voxel in the biological sample; pooling tagged microsamples; dividing the pooled sample into a plurality of subsamples, such that a plurality of subsamples comprise cells and/or nuclei from different original microsamples or voxels.

  • Publication number: 20250019685
    Abstract: A system, methods, and apparatus are described to collect and prepare single cells and groups of cells from microsamples of specimens and encode spatial information of the physical position of the cells in the specimen. In some embodiment, beads or surfaces with oligonucleotides containing spatial barcodes are used to analyze DNA or RNA. The spatial barcodes allow the position of the cell to be defined and the nucleic acid sequencing information, such as target sequencing, whole genome, gene expression, used to analyze the cells in a microsample for cell type, expression pattern, DNA sequence, and other information, in the context of the cell's physical position in the specimen. In other embodiment, markers such as isotopes are added to a microsample to encode spatial position with mass spectoscopy or other analysis. The spatial encoded information is then readout by analysis such as DNA sequencing, mass spectrometry, fluorescence, or other methods.

  • Publication number: 20240027311
    Abstract: This disclosure provides methods for producing a sample of subcellular organelles, particularly nuclei, from a tissue. In some embodiments, this disclosure provides a method of processing a tissue sample involves performing enzymatic/chemical disruption of tissue in a chamber to produce disrupted tissue comprising released cells and/or nuclei and debris; separating the released cells and/or nuclei from the debris therein; and moving the released cells and/or nuclei. In some instances, the method comprises mechanical disruption of the tissue sample.
