VitroGel® Organoid Recovery Solution

• Works both with cells cultured with VitroGel hydrogels or an animal-based ECM

• Fast 2-minute dissociation of animal-based ECM for intact organoids/cells

• High Yield – Complete ECM dissociation for a high recovery rate for organoid expansion

• Supports cell recovery from 2D ECM coating plate

• Non-enzymatic stable formulation

• Easy-to-use with room temperature operation

• Longer shelf life than competitors. No cold pack shipping.

VitroGel® Organoid Recovery Solution is a non-enzymatic cell harvesting solution for quick and efficient recovery of 3D cells or organoids cultured with either VitroGel® hydrogels or an animal-based ECM.

For cells/organoids cultured in an animal-based ECM, achieve fast 2-minute ECM dissociation safely and efficiently.

VitroGel Organoid Recovery Solution is room temperature stable and has a neutral pH. The solution can maintain high cell viability during the recovery process. Harvested cells can be subcultured in both 3D and 2D cultures. The VitroGel Organoid Recovery Solution can be used before or after the fixation and stained preparation of hydrogel specimens to ensure high-quality downstream data analysis.

DATA AND REFERENCES

Figure 1. Organoids recovered from Matrigel using VitroGel Organoid Recovery Solution with two methods.
Method 1: Re-suspend organoids in VitroGel Organoid Recovery Solution by pipetting to break organoids into small fragments for sub-culture/expansion.
Method 2: Rocking the tube with organoids and VitroGel Organoid Recovery Solution mixture without using a pipette to harvest the intact organoids.
In both, VitroGel Organoid Recover Solution was kept in a 4 °C refrigerator to maintain a low temperature before use. The organoids/Matrigel and VitroGel Organoid Recovery Solution mixture were incubated at room temperature for 2 min before centrifuging. Day 0 images show the morphology of organoids right after harvesting with two different methods.

Figure 2. Comparison of VitroGel Organoid Recovery Solution and VitroGel Cell Recovery Solution for organoids recovered from Matrigel.
Organoids (Passage 19) were cultured in Matrigel for three days before harvesting. 1 mL cold (4 °C) VitroGel Organoid Recovery Solution (MS04) or VitroGel Cell Recovery Solution (MS03) was added to a well of a 24-well plate to resuspend the organoid-Matrigel dome. The mixture was genteelly pipetted, transferred to a centrifuge tube, and incubated at room temperature for 2 min (MS04) and 10 min (MS03), respectively. After centrifuging to collect the organoids, the Matrigel in MS04 solution was completely dissolved. For the MS03 solution, there was a small amount of soft gel remaining on top of the organoids. The organoids harvested from both conditions were sub-cultured in Matrigel. The images above (Passage 20, Days 1&2) show the healthy organoid expansion from both cell recovery solutions. VitroGel ORGANOID Recover Solution shows a higher recovery efficiency than the VitroGel Cell Recover Solution in this study.

Figure 3. Comparison of VitroGel Organoid Recovery Solution with other organoid recovery solutions.
The data above shows the comparison study of VitroGel Organoid Recovery Solution (MS04) with other organoid recovery solutions (Solution RLR from Company SC and Solution 3ODR from Company SA). All solutions were used directly from a 4 °C refrigerator. After mixing with organoid/Matrigel, the mixture with MS04 was incubated at room temperature for 2 min, while the mixture with Solution RLR or Solution 3ODR was incubated in an ice bucket for at least 15 min. After centrifuging, all Matrigel in the MS04 mixture was dissolved, but most Matrigel remained in both Solution RLR and Solution 3ODR conditions. Besides recovering intact organoids, the organoids from the MS04 solution can be easily resuspended in a cell culture medium and broken into small fragments for a subculture (MS04 images above). However, the organoid/Matrigel mixture was hard to break in Solution RLR or Solution 3ODR. VitroGel Organoid Recovery Solution delivers a higher cell recovery rate for organoid expansion.
