Advancing your pluripotent stem cell therapy research to clinical applications requires careful material selection as the quality of starting materials significantly impacts the properties of your final stem cell therapy product.

At Thermo Fisher Scientific, we have developed Gibco Cell Therapy Systems (CTS) products across the pluripotent stem cell therapy workflow to ease the transition from discovery to commercial manufacturing. We offer high quality GMP manufactured, commercial scale ancillary materials with a high degree of qualification, traceability, and regulatory documentation.

  • Scalable manufacturing under GMP conditions - Gibco media and supplements are manufactured in conformity with Good Manufacturing Practices (GMP) for medical devices, 21 CFR Part 820, and follow USP<1043> and Ph Eur 5.2.12, and our manufacturing sites are FDA-registered and ISO 13485- and/or ISO 9001-certified. Our investment in rigorous product manufacturing ensures the consistency, reliability, and high quality of PSC therapy reagents in combination with the ability to scale up and accommodate changing needs.
  • Quality control testing and regulatory documentation - CTS media and reagents help minimize the risk of contamination and variability in your research with extensive safety testing, including sterility, endotoxin and mycoplasma. Full traceability for raw materials is also available, including Drug Master Files and/or Regulatory Support Files, and certificates of origin.
  • Proven use for a seamless transition from research to clinic - We offer an extensive selection of serum-free, xeno-free, or animal origin–free formulations with cell therapy specific intended use statements and complementary research use reagents. Our CTS products have been used in over 200 clinical trials as well as in commercially approved cell therapies including FDA-approved CAR-T therapies and the first FDA-approved therapeutic cancer vaccine.

NEW Gibco CTS Rotea™ Counterflow Centrifugation System

Gibco CTS Rotea Counterflow Centrifugation System

A compact, flexible closed cell processing system, designed to streamline and expedite your cell therapy development, that enables:

  • Process flexibility—user-programmable software enables you to create and optimize a broad range of protocols for cell separation, washing, and concentration
  • High cell recovery and viability—gentle processing enables >95% cell recovery while maintaining cell viability
  • Low output volumes—proprietary technology can deliver as little as 5 mL of concentrate
  • Research through commercial manufacturing—the closed single-use kit enables sterile processing, and an OPC-UA interface enables connectivity to a 21 CFR Part 11-compliant system

CTS Essential 8 Medium

Gibco CTS Essential 8 Medium

Based on the widely cited Essential 8 Medium, Gibco CTS Essential 8 Medium is the first globally available human pluripotent stem cell (hPSC) culture medium with components not directly derived from animals.

  • Supports long-term iPSC culture—maintains iPSC marker expression and a normal karyotype over multiple passages
  • Maintains differentiation potential—PSCs cultured in CTS Essential 8 Medium are able to generate cells of all three germ layers
  • Helps reduce risk—based on the same fully defined and highly consistent eight-component formulation as RUO Essential 8 Medium but without components directly of animal or human origin

CTS Essential 6 Medium

Gibco CTS Essential 6 Medium

Gibco CTS Essential 6 Medium is a xeno-free, feeder-free medium which supports the spontaneous or directed differentiation of human pluripotent stem cells (hPSCs) and the reprogramming of somatic cells.

  • Provides a flexible format—suits different applications and various cell types
  • Simplifies the transition from bench to clinic—contains the same six essential components as RUO Essential 6 Medium, and with its cGMP manufacturing process, this formulation helps minimize variability
  • Supports differentiation and reprogramming—does not contain bFGF or TGFbeta

CTS Vitronectin (VTN-N) Recombinant Human Protein

Gibco CTS Vitronectin (VTN-N) Recombinant Human Protein

Designed in the laboratory of James Thomson, Gibco CTS Vitronectin (VTN-N) Recombinant Human Protein is a defined matrix for feeder-free culture of iPSCs and is intended for use with the CTS Essential 8 culture system.

  • Animal origin–free—microbial expression recombinant matrix helps reduce variability and viral contamination risk in iPSC cultures
  • Optimized and defined surface—VTN-N variant has been shown to support human iPSC attachment and survival better than wild type vitronectin
  • Supports pluripotency—able to maintain pluripotency, normal growth characteristics, trilineage differentiation potential and normal karyotype after extended culture

CTS RevitaCell Supplement

Plastic 5 mL vial containing clear CTS RevitaCell Supplement

Gibco CTS RevitaCell Supplement (100X) is an animal-origin-free, chemically defined supplement used with PSCs for post-thaw recovery or in combination with CTS Essential 8 Medium for single cell passaging. 

  • Improved cell survival—provides high cell viability post-single cell passaging and post-thaw
  • Contains higher specificity inhibitor—includes a higher specificity ROCK inhibitor, coupled with antioxidants and free radical scavengers to minimize impact of stress on cells
  • Offers consistency—formulated using animal-origin free and chemically defined materials

CTS Versene Solution

Plastic 100 mL supplement bottle containing clear CTS Versene

Gibco CTS Versene is a gentle non-enzymatic cell dissociation reagent for routine clump passaging of PSCs while maintaining viability over multiple passages.

  • Maintain viability over multiple passages—PSCs passaged with this cGMP manufactured EDTA dissociation reagent maintain viability
