2. How are InSphero 3D tumor microtissues made?
InSphero employs the GravityPLUS platform to precision mass-fabricate standardized tumor micro-
tissues with a size variability of 10%. The GravityPLUS process gently coerces cells to assemble together
by gravity. This method completely avoids the use of polymeric scaffolds that could potentially interact
with drug compounds, assay reagents or cells.
What are 3D tumor microtissues?
Tumor microtissues are also known as multicellular tumor spheroids. These highly biomimetic 3D tumor
models display the gene expression patterns and the histomorphological, functional and microenviron-
mental features of in vivo human tumor tissue. 3D tumor microtissues are ideal for drug discovery and
far more predictive of clinical efficacy compared to 2D cultures. At last these valuable 3D models are
conveniently available “off-the-shelf” in large quantities, ready-for-use in high-throughput applications.
Biomimetic features
The GravityPLUS process results in the rapid formation of cell-cell contacts, cell-cell communication, cell
type-specific extracellular matrix and cell-matrix interaction. The morphology and functionality of the in
vivo tumor is clearly evident. In fact, unlike cells in 2D, InSphero tumor microtissues distinctly resemble
tissue from the inter-vascular regions of solid tumors.

3. One Dimension
ahead Advantages of InSphero Tumor Microtissues
More biomimetic: Compared to 2D monolayers, InSphero’s 3D microtissues can help to establish more
predictive in vitro drug testing, since phenomena such as multicellular resistance are clearly evident
No scaffolds: Polymeric scaffolds are not used which means freedom from concerns about unknown
and unwanted assay artefacts due to scaffold interactions with drug compounds, assay reagents or cells.
Assay-ready: InSphero tumor microtissues are available in industrial-scale quantities, in standard
96-well format, ready for screening or other HT applications.
Longer culture lifetime: Whereas 2D monolayer cultures offer only a very narrow time window for
gathering data this is extended many-fold with InSphero’s tumor microtissues.
Use your own cell lines: Complement InSphero’s off-the-shelf offer with your own cell lines in 3D
using InSphero’s custom production services.
