We present a protocol to obtain cell-derived matrices rich in extracellular matrix proteins, using macromolecular crowders (MMC). In addition, we present a protocol which incorporates MMC in 3D organotypic skin co-culture generation, which reduces culture time while maintaining maturity of construct.

This protocol demonstrates methods used to establish 2D and 3D environments in custom-designed electrotactic chambers, which can track cells in vivo/ex vivo using time-lapse recording at the single cell level, in order to investigate galvanotaxis/electrotaxis and other cellular responses to direct current (DC) electric fields (EFs).

Chromosome painting is a useful method for studying organization of the cell nucleus and evolution of the karyotype. Here, we demonstrate an approach to isolate and amplify specific regions of interest from single polytene chromosomes that are subsequently used for two- and three-dimensional fluorescent in situ hybridization (FISH).

2D Co-culture of Leukemic Cells with BMSCs: A Method to Obtain Subpopulations of Leukemic Cells
0 Views •
2023
This video describes the technique for long term 2D co-culture of leukemia cells with bone marrow stromal cells to study their interaction with the bone marrow microenvironment. The 2D coculture model utilizes the acute lymphoblastic leukemia cells and the bone marrow stromal or osteoblasts that influence tumor cell phenotype. This study will support investigation of the mechanisms that underlie bone marrow supported survival of leukemic cells during chemotherapy exposure.
FAQs
The central distinction is how spatial organization changes the cellular environment. A flat substrate emphasizes attachment and spreading across a surface, whereas aggregates, scaffolds, or biomaterial matrices create more opportunities for cell-cell interaction, extracellular-matrix contact, and chemical gradients. These differences can alter how faithfully a model represents tissue-like behavior, making geometry a key experimental variable.
A model should match the biological question rather than be selected solely for convenience. Two-dimensional systems support controlled study of cell behavior on a surface, while three-dimensional systems may provide tissue-like organization relevant to cell interactions, matrix contact, and gradients. Bioengineers therefore compare model complexity with the level of biological realism needed for the experiment.
Parallel use of both platforms can reveal whether an observed response depends on spatial organization. Differences in cell behavior, disease processes, drug responses, or tissue formation may indicate that the surrounding structure influences the result. This comparison helps distinguish findings that remain consistent across systems from those that emerge only in a more tissue-like construct.
They provide a three-dimensional setting in which cells can organize beyond a flat surface. In bioengineering, this arrangement supports investigation of cell-cell interactions, extracellular-matrix contact, and chemical gradients within a construct. Such features make scaffolds and matrices especially relevant when the goal is to study tissue formation or design models for regenerative medicine.
Start with the biological or engineering objective, then ask whether the study requires surface-based cell spreading or a more tissue-like arrangement. Select a 2D or 3D platform accordingly, and use the resulting system to examine cell behavior, disease, drug responses, or tissue formation. Comparing complementary formats can strengthen interpretation when spatial context may affect outcomes.
Three-dimensional systems can be organized as cell aggregates, scaffolds, or biomaterial matrices. The choice determines how cells are spatially arranged and how they encounter neighboring cells, extracellular matrix, and chemical gradients. These components are not interchangeable in experimental interpretation: each represents a different engineered environment for studying tissue formation and cellular responses.
2D culture is useful when the experiment focuses on how cells attach to and spread across a flat substrate. Its controlled surface provides a comparatively direct setting for examining cell behavior and responses in a laboratory system. Bioengineers can use this format when spatial organization within a tissue-like construct is not the primary feature required by the research question.
