VitroGel® ORGANOID

Ready-to-use, xeno-free hydrogel for organoid formation and expansion.​

VitroGel® ORGANOID (1-4) are xeno-free (animal origin-free) hydrogels that support the growth of patient-derived organoids or organoids developed from pluripotent stem cells (PSCs), co-culture, and PDX model.

VitroGel® ORGANOID hydrogels are ready to use at room temperature and have 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. VitroGel® ORGANOID hydrogels are good for both 3D cell culture and 2D hydrogel coating applications.

The VitroGel® ORGANOID hydrogels can work in conjunction with VitroGel® STEM (a xeno-free hydrogel for 3D static suspension cultures and scale-up of human pluripotent stem cells) by transferring stem cell spheroids cultured in VitroGel® STEM to VitroGel® ORGANOID hydrogels for organoid differentiation. See Xeno-free 3D Organoid Workflow Key growth factors and molecules can be directly mixed with the hydrogel matrix or by adding on the top of the hydrogel. Organoids cultured in this system can be easily harvested out with our VitroGel® Organoid Recovery Solution.  VitroGel® ORGANOID hydrogels provide a well-defined 3D microenvironment for the future of personalized medicine.

We still strongly suggest starting with the VitroGel® ORGANOID Discovery Kit (Cat# VHM04-K) to make a quick screening to find the hydrogel version that is optimal for the organoid conditions.
 
The kit includes all four types of organoid hydrogels:
VitroGel® ORGANOID-1, VitroGel® ORGANOID-2, VitroGel® ORGANOID-3, VitroGel® ORGANOID-4)
Each of the four types has various bio-functional ligands, mechanical strengths, and degradability to fulfill the needs of different organoid culture conditions.
 
Because there is a wide range of organoid cell resources (from stem cells, patient-derived tissue, co-culture, to PDX), it is hard to tell which organoid hydrogel would best perform the researcher’s experiment. Therefore, the Discovery Kit helps researchers to screen the four different formulations to determine the best organoid hydrogel version for the organoid conditions.
 
From our findings, versions 1, 2, or 3 are suitable for gastric organoids. Versions 1 or 3 are suitable for lung organoids. Versions 2 or 3 are suitable for brain organoids, and versions 3 or 4 are suitable for cancer organoids.

Figure 2. Culture human intestinal organoid from stem cell spheroids.
Human iPSCs recovered from liquid nitrogen were seeded with VitroGel® STEM for static suspension culture (Refer to protocol of VitroGel® STEM Cat# VHM02). The high-quality stem cell spheroids formed within 3-5 days with full pluripotent properties (showing the positive markers of SSEA4, OCT4, SOX2, and TRA-1-60). The spheroids were harvested by centrifuging (100 x g, 3 min), and resuspended with VitroGel® STEM in endoderm differentiation medium for 3 days. The endoderm cell spheroids were then harvested by centrifuging (100 x g, 3 min), and resuspended with VitroGel® STEM in mid/hindgut differentiation medium for 3-4 days. The mid/hindguts were collected by centrifuging (100 x g, 3 min), and characterized with CDX2 and E-Cadherin. The mid/hindguts were resuspended with organoid formation medium and mixed with VitroGel® ORGANOID (following the protocol of VitroGel® ORGANOID) for organoid formation and long-term maturating culture.

Organoid FAQ

Adding hydrogel as a dome may cause the gel floating issue. Therefore, we don’t recommend the dome method; however, some customers still want to adopt the dome method. At this point, the non-tissue culture-treated plate can hold the dome better than the TC-Plate with some tips. You may need to add the dome as soon as you mix the gel and cells. Also, warming up the medium can help a little (slow down the gel formation’s speed).

However, the dome method is not 100% successful with non-TC plates, and some scientists really have a hard time with it. That is why we recommend covering the whole bottom of the well with our hydrogel. We usually use a 48 or 96-well plate (about 100-150 uL per well of a 48-well plate or 50 uL per 96-well plate). For full bottom coverage, the TC plate is better. Alternatively, you could coat the plate with 0.1-0.5% gelatin for 10 minutes and then remove the gelatin before adding the hydrogel.

For the dome method,

  • The non-tissue culture-treated plate works better for hydrogel to hold the dome shape (25 uL hydrogel in each well of the 24-well plate).
  • However, if you use the hydrogel the cover the whole bottom of the well plate, the tissue culture-treated plate helps the hydrogel to spread and cover the whole bottom of the well plate (sealing the edge of the bottom and wall of each well better), which can help to hold the hydrogel at the bottom of the well plate.
  • Alternatively, you could coat the plate with 0.1-0.5% gelatin for 10 minutes and then remove the gelatin before adding the hydrogel.

Because there is a wide range of organoid cell resources from stem cells, patient-derived tissue, co-culture, and PDX, it is hard to tell which organoid hydrogel would perform the best for the researcher’s experiment. Therefore, the VitroGel®  ORGANOID Discovery Kit helps researchers screen the four different formulations to determine the best organoid hydrogel version for your organoid conditions.

The VitroGel® ORGANOID Discovery Kit includes the four different formulation types of VitroGel® ORGANOID hydrogels in 2mL :

  • VitroGel® ORGANOID 1
  • VitroGel® ORGANOID 2
  • VitroGel® ORGANOID 3
  • VItroGel® ORGANOID 4

Each of the four types has various bio-functional ligands, mechanical strengths, and degradability to fulfill the needs of different organoid culture conditions. From our findings, versions 1, 2, or 3 are suitable for gastric organoids. Versions 1 and 3 are suitable for lung organoids. Version 2 or 3 are suitable for brain organoids, and versions 3 or 4 are suitable for cancer organoids. By saying that, we still suggest using the Discovery Kit to screen the optimal hydrogel for your organoid conditions quickly.

The VitroGel® ORGANOID has four different versions, each formulated with various biofunctional ligands, mechanical strengths, and degradability to fulfill the needs of different organoid culture conditions.

The VitroGel® ORGANOID-3 would be a good starting point as many researchers get good results on this hydrogel for their organoid culture.
