The RocketCell™ Organoid Xeno-Free Essential-Core Medium Kit (TheWell
Bioscience, Cat# RC04-OCM) is a standardized, chemically defined foundation medium designed to simplify and unify organoid culture workflows. This ready-to-use kit serves as a fundamental medium that provides all essential nutrients and is flexible, allowing direct mixing with growth factors and signaling molecules to support various types of organoid development. It eliminates the need for conditioned media preparation or complex multi-component media and supplement mixing.
This advanced Essential-Core formulation replaces multiple supplementation steps (such as N2/B27) with a single, defined system. Researchers can generate customized, organoid-specific media simply by adding the desired growth factors and signaling molecules.
Developed to support long-term expansion, high post-passaging viability, and reproducible outcomes, RocketCell™ Essential-Core Medium establishes a flexible, xeno-free platform for diverse organoid systems in both synthetic and animal-derived hydrogels. This medium supports organoids from different sources and can also serve as a flexible base for formulating differentiation media tailored to the developmental stages of iPSC-derived organoids. By providing a unified and consistent core formulation, this kit enables the establishment of standardized, reproducible workflows for organoid culture across research, translational, and industrial settings.

RocketCell™ Organoid Xeno-Free Essential-Core Medium and commercial intestinal organoid media were prepared according to the manufacturer’s instructions. The 1X RocketCell™ Organoid Xeno-Free Essential-Core Basal Medium was then supplemented with intestinal organoid-specific growth factors (e.g., Wnt pathway agonists, EGF, Noggin, and R-Spondin1). Organoids were cultured in an animal-derived gel (Matrigel) as domes, and growth was compared between 2 media types. (A&B) Organoid fragments cultured in media prepared using RocketCell™ Organoid Xeno-Free Essential-Core Medium and commercial intestinal organoid media: Day 0.
