- Supports a wide range of organoids from patient-derived samples, stem cells, tissues, co-culture and PDX resources
- Scalable protocol for lab automation
- Easy 20-minute cell harvesting (enzyme-free)
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 B. 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 Cell Recovery Solution. VitroGel ORGANOID hydrogels provide a well-defined 3D microenvironment for the future of personalized medicine.

Application Notes / Research Highlights
VitroGel Organoid Methods vs Natural ECM Methods
VitroGel ORGANOID system can culture organoids in variety of methods:
- 2D hydrogel coating
- 3D cell culture encapsulation
- Hydrogel-Cell droplet (A unique method only to VitroGel ORGANOID)
Review all the following VitroGel ORGANOID protocol methods compared to the natural ECM methods and choose the one that best fits your project
2D Hydrogel Coating
Add cells on top of hydrogel for optimal interactions among cells, hydrogel, and medium.
3D Cell Culture Encapsulation
Encapsulate cells within the hydrogel for excellent mechanical support and the cell-matrix interactions.
Create a VitroGel-Cell droplet. This is a unique culture method only to the VitroGel system for generating great cell-matrix interactions and excellent medium penetration for organoid formation and scale-up.

Xeno-free 3D Organoid Workflow A:
Using VitroGel ORGNAOID for organoid culture and maturation
Figure 1. MOUSE INTESTIONAL ORGANOID culture on VitroGel ORGANOID and Matrigel.
Small organoids recovered from liquid nitrogen were directly seeded with VitroGel and Matrigel, respectively. Images show the growth of mouse intestinal organoid from day 0 to day 14.
Xeno-free 3D Organoid Workflow B:
Start from iPSC spheroids for stem cell differentiation and organoid formation.
(Diagram below shows culturing human intestinal organoid from stem cell spheroids)
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.

Organoids are embedded in VitoGel ORGANOID-3 (left) and Matrigel(right). Poor movement of MoDCs (green) when co-cultured with and HGOs (red) embedded in Matrigel. Improved migration of MoDCs (green) towards HGOs (red) embedded in VitroGel ORGANOID-3.

Human gastric organoids (HGOs) were passaged by trypsinization then resuspended in gel using either (A) 50% L-WRN conditioned media (CM), the recommended growth factor concentrations or (B) whole L-WRN CM (100%), doubling the concentration of the organoid growth factors Wnt3a and Rspondin. HGOs were imaged one day after passaging (day 1) and five days later. (C) On day 1 and 5 the diameter of 20 organoids from each condition was compared.
