VitroGel® 3D High Concentration

VitroGel® 3D High Concentration is a tunable, xeno-free (animal origin-free) hydrogel system that allows the maximum flexibility to manipulate the 3D cell culture environment for different needs. VitroGel 3D High Concentration comes with VitroGel Dilution Solution to adjust the final hydrogel strength from 10 to 4000 Pa. The hydrogel’s tunability gives researchers the ability to create an optimized environment for cell growth. The VitroGel 3D High Concentration hydrogel matrix structure is good for cell spheroid formation, suspension cells, or cells requiring low cell-matrix interactions.

VitroGel High Concentration hydrogels are our xeno-free, tunable hydrogels for researchers wanting full control to manipulate the biophysical and biological properties of the cell culture environment. The tunability of the hydrogel gives the ability to create an optimized environment for cell growth. The hydrogel system has a neutral pH, transparent, permeable, and compatible with different imaging systems. The solution transforms into a hydrogel matrix by simply mixing with the cell culture medium. No cross-linking agent is required. Cells cultured in this system can be easily harvested with our VitroGel® Cell Recovery Solution. The hydrogel can also be tuned to be injectable for in vivo studies.

From 3D cell culture, 2D cell coating to animal injection, VitroGel makes it possible to bridge the in vitro and in vivo studies with the same platform system.

3D Cell Culture Process in 20 Minutes

VitroGel High Concentration hydrogels are easy-to-use. There is no cross-linking agent required. Work confidently at room temperature.

Tunable Hydrogel Strength

Simply diluting the hydrogel controls the gel strength

Under 3D culture of VitroGel 3D, BL5 cells form islet-like structures very similar to normal human islets. The hydrogel is prepared at 1:3 dilution. The images were taken at 10X magnification.

CD8+ T cells culture grew in suspension culture (control); B. 3D culture of CD8+ T cells in VitroGel 3D at Day 7. CD8+ T cells are vibrant in 3D culture conditions of VitroGel 3D. The cells can easily move within the unmodified hydrogel matrix. The hydrogel is prepared at 1:3 dilution. The images were taken at 10X magnification.

2D COATING APPLICATIONS

Figure 3. Human colon cancer cells (HCT 116) cells cultured on top of VitroGel 3D hydrogel.
A thick hydrogel coating plate has been prepared by mixing VitroGel 3D with PBS at 1:1 ratio. A 300 µL mixture has been added to a well of a 24-well plate and stabilization at room temperature for 20 minutes before adding cells on top of the hydrogel. Cell spheroids form on the top of the hydrogel. Cells seeded at 2.5-10×105 cells/mL.

Figure 4. Comparison of long-term neuronal culture seeded onto thick hydrogel mats.
Cells are stained with Beta-III-Tubulin (green) cytoskeleton marker and their nuclei are counter-stained with DAPI (blue). Cells spread out and form neural-like networks as early as day 3 post-differentiation, with comparable efficacy between VitroGel 3D and Matrigel, based on cell survival, culture spreading, and morphological analysis reached between days 7 and 9. On Matrigel mats, cell culture health and viability drop off sharply once day 9 has passed, with most cells detaching and neurites retracting by day 14 and the vast majority of cells gone by day 21. If grown onto VitroGel 3D mats, differentiated B35 neurons have a tendency to self-organize into 3D clusters very early on (Day 7), assuming a mixed 2D/3D cell culture for the first two weeks of the time course. By Day 21, these cells have migrated into self-assembled 3D clusters, embedded into the thick hydrogel matrix, with very few cells between the clusters, but without any significant cell death.

A. Priess cells grown in suspension (control); B. Priess cells grown on top of VitroGel 3D at day 7. A hydrogel substance can be prepared with different stiffness by adjusting the dilution of VitroGel 3D from 1:1 to 1:3 ratio. Cells seeded on the top of the hydrogel form cell spheroids form on the top of the hydrogel. The hydrogel provides a soft substance for cells to attach and grow.
