RocketCell™ EMT Supplement (50X), XF
Xeno-free supplement for 3D spheroid and tumoroid culture
Xeno-Free Formulation
Supports the development and maintenance of 3D spheroid and tumoroid cultures without FBS or other animal-derived components, providing a more defined alternative to conventional serum-based workflows.
Long-Term 3D Culture
Prolonged spheroid and tumoroid cultures for extended studies of tumor biology and therapeutic response.
Supports Spheroid-to-tumoroid Development
Facilitates continued growth and development of established
spheroids into larger, more complex 3D tumoroids when used
with VitroGel® EMT hydrogel.
Versatile Cancer Research Applications
Supports 3D models for investigating tumor growth and progression, EMT- associated changes, therapeutic response, and drug screening.
RocketCell™ EMT Supplement (50X), XF is a xeno-free supplement designed to support the development and maintenance of 3D spheroid and tumoroid models for cancer research.
When combined with VitroGel® EMT hydrogel and the VitroPrime™ Ultra-Low Attachment, U-bottom, 96-well plate, the RocketCell™ EMT
Supplement supports continued growth and development of established spheroids into larger, more complex tumoroids.
The resulting 3D models provide a defined platform for studying tumor growth and progression, EMT-associated changes, therapeutic response, and cancer drug screening.

CASE 1
3D Tumoroid formation with the RocketCell™ EMT Supplement (50X), XF

Figure 1: VitroGel® Glioblastoma EMT Kit, XF supports tumoroid formation.
U87 MG cells were resuspended in basal medium supplemented with 1X RocketCell™ EMT Supplement, XF, and seeded into the VitroPrime™ Ultra-Low Attachment Plate, U-Bottom, 96-Well, to promote overnight spheroid formation.
The spheroids were supplemented with VitroGel® EMT and RocketCell™ EMT Supplement, XF to induce tumoroid generation. Light microscopy was performed over multiple days to evaluate tumoroid growth over time (left). Cyto3D® Live-Dead Assay staining was performed on GBM tumoroids. Live cells within the tumoroid are shown as green and dead cells in red (right).
CASE 2
Tumoroids grown with the VitroGel® Glioblastoma EMT Kit, XF as a Platform for Drug Screening

Figure 2: GBM tumoroids are susceptible to chemotherapy.
Tumoroids were grown for 3 days in VitroGel® EMT hydrogel with RocketCell™ EMT Supplement (50X), XF. The tumoroids were treated with Temozolomide (TMZ; 1mM) for 24 hours and subjected to cell viability studies.
Cyto3D® Live-Dead Assay Kit was used to label live cells (green) and dead cells (red) in the tumoroid, both with and without drug treatment. The pictures were obtained at a 20X magnification.
