  2. 3D cell culture - Wikipedia

    en.wikipedia.org/wiki/3D_cell_culture

    A 3D cell culture is an artificially created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions. Unlike 2D environments (e.g. a Petri dish), a 3D cell culture allows cells in vitro to grow in all directions, similar to how they would in vivo. [1]

  3. Cell culture - Wikipedia

    en.wikipedia.org/wiki/Cell_culture

    Currently, there is an increase in use of 3D cell cultures in research areas including drug discovery, cancer biology, regenerative medicine, nanomaterials assessment and basic life science research. [66] [67] [68] 3D cell cultures can be grown using a scaffold or matrix, or in a scaffold-free manner. Scaffold based cultures utilize an ...

  4. 3D cell culturing by magnetic levitation - Wikipedia

    3D cell culture methods have been developed to enable research into the behavior of cells in an environment that represents their interactions in-vivo more accurately [5].. 3D cell culturing by magnetic levitation uses biocompatible polymer-based reagents [2] to deliver magnetic nanoparticles to individual cells, so that an applied magnetic driver can levitate cells off the bottom of the cell ...

  5. Wound healing assay - Wikipedia

    en.wikipedia.org/wiki/Wound_healing_assay

    Scratch wound healing assay experiment of rhabdomyosarcoma, a cancer cell line. A wound healing assay is a laboratory technique used to study cell migration and cellcell interaction. This is also called a scratch assay because it is done by making a scratch on a cell monolayer and capturing images at regular intervals by time lapse ...

  6. Organ-on-a-chip - Wikipedia

    en.wikipedia.org/wiki/Organ-on-a-chip

    [8] [9] Brain-on-a-chip devices can span multiple levels of complexity in terms of cell culture methodology and can include brain parenchyma and/or blood-brain barrier tissues. [10] Devices have been made using platforms that range from traditional 2D cell culture to 3D tissues in the form of organotypic brain slices and more recently organoids.

    For about 1% of those ages 50 to 79, test results will show a cancer signal was detected, along with the organ or tissue type associated with that specific cancer signal.

  8. Mammography - Wikipedia

    These images are then analyzed for abnormal findings. It is usual to employ lower-energy X-rays, typically Mo (K-shell X-ray energies of 17.5 and 19.6 keV) and Rh (20.2 and 22.7 keV) than those used for radiography of bones. Mammography may be 2D or 3D (tomosynthesis), depending on the available equipment or purpose of the examination.

  9. Tissue culture - Wikipedia

    en.wikipedia.org/wiki/Tissue_culture

    The third method is cell culture, of which there are three types: (1) precursor cell culture, i.e. undifferentiated cells that are to be differentiate, (2) differentiated cell culture, i.e. completely differentiated cells that have lost the capacity to further differentiate, and (3) stem cell culture, i.e. undifferentiated cells that can ...
