Overview

VitroGel® 3D is a pure and unmodified hydrogel that allows the maximum flexibility to manipulate the 3D cell culture environment for different needs. The unmodified hydrogel matrix structure is good for cell spheroid formation, suspension cells or cells requiring low cell-matrix interactions.

VitroGel 3D is one system of the family of ready-to-use, xeno-free tunable hydrogel system which closely mimics the natural extracellular matrix (ECM) environment.

VitroGel creates a functional and optimized environment to make cells feel like at home. The hydrogel system is room temperature stable, has a neutral pH, transparent, permeable and compatible with different imaging systems. The solution transforms into a tunable hydrogel matrix by simply mixing with the cell culture medium. Cells cultured in this system can be easily harvested out 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.

  • How to prepare the cell suspension to mix the hydrogel? Shall I add serum?
    If cells cultured in a complete cell culture medium, which is supplement with 10% FBS or other critical supplements, please prepare the cell suspension using the following methods before mixing it with hydrogel solution.

    1. Prepare the cell suspension with 2X concentration (e.g. 100K), and mix with 100% FBS at 1:1 (v/v) ratio to get 1X cell suspension (50K) with 50% FBS.
    2. Mix the diluted hydrogel solution with the cell suspension from above at 4:1 (v/v) ratio to get the final cells in the hydrogel at 10K with 10% FBS supplement.

    If serum plan is an important role in your traditional cell culture, it is also important for 2D coating and 3D culture. Adding serum supplements in the hydrogel and adjusting the final serum concentration to the target level would support cell growth in the hydrogel system.

  • How do I adjust the hydrogel formation time?

    –  If VitroGel needs to be diluted more than 1:3 ratio, a longer waiting time (20-30 min) may be needed for soft gel formation. Using a higher volume of cell culture medium for mixing would help to accelerate the process of hydrogel formation.-  If the hydrogel solidifies too fast after mixing with culture medium (showing as small solid gel chunk), adjust the mixing ratio by using less cell culture medium. For example, if mixing 4 mL diluted hydrogel solution with 1 mL cell culture medium lead to the solid gel chuck (particles), then mixing 4 mL diluted hydrogel solution with 0.5-0.8 mL cell culture medium would help to solve the issue.-  On the other hand, if the hydrogel formation is too slow, which may happen when using low hydrogel concentration at 1:3 or 1:4 dilution or using a cell culture medium with very low ionic concentration, adjust the mixing ratio by using more cell culture medium. For example, if mixing 4 mL diluted hydrogel solution with 1 mL cell culture medium lead to a slow hydrogel formation, then mixing 4 mL diluted hydrogel solution with 1.5-4 mL cell culture medium would help to solve the issue.
  •  How do I adjust the stiffness of the final hydrogel?
    The stiffness of the final hydrogel can be adjusted by diluting the hydrogel solution before mixing with cell culture media. Our VitroGel Dilution Solution can help to adjust the hydrogel concentration. Please read the “First-time User Note” to learn how to prepare different VitroGel dilutions. If you need a higher hydrogel stiffness than the original product, please contact us at support@thewellbio.com.

  • Can I harvest cells from the hydrogel after 3D culture?
    Yes, the cells can be harvested after 2D coating or 3D culture by using the VitroGel Cell Recovery Solution. VitroGel™ Cell Recovery Solution is a ready-to-use, enzyme-free solution to harvest 2D or 3D cultured cells from hydrogel fast and safely. The solution is compatible with the VitroGel hydrogel system and can recover cells from VitroGel in 15 minutes. VitroGel Cell Recovery Solution is room temperature stable, has a neutral pH and works at 37 °C operating temperature. The solution can maintain high cell viability during the recovery process. Cells can be sub-culture in both 2D and 3D culture after recovery.

3D Cell Culture Applications

Figure 1. Beta Lox 5 (BL5) cells 3D culture in VitroGel 3D system.

A. BL5 cells culture on the surface of regular tissue culture treated well plate (control); B. Normal human islets grew in suspension culture (comparison); C. 3D culture of BL5 cells in VitroGel 3D at Day 1; D. 3D culture of BL5 cells in VitroGel 3D at Day 7. 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.

The cells can easily move within the unmodified hydrogel matrix. The hydrogel is prepare 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 min 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 drops 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.

Figure 5. Human Lymphoblastoid Priess cells cultured on top of VitroGel 3D hydrogel

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 hydrogel. The hydrogel provides a soft substance for cell to attach and grow.
