RSeT™ Feeder-Free Medium
Serum-free medium for naïve-like human pluripotent stem cells
RSeT™ Feeder-Free Medium
Serum-free medium for naïve-like human pluripotent stem cells
Product Advantages
- Feeder-independent culture system reduces inherent variability, cost, and burden of feeder preparation
- Serum-free formulation contains pre-screened quality components for reproducible results
- Facilitates highly efficient reversion to naïve-like state with stable domed morphology, naïve gene expression profiles, and low levels of spontaneous differentiation without the need for exogenous genes
- Maintains naïve-like pluripotency without inclusion of bFGF
What's Included
Overview
Developed under license from the Weizmann Institute of Science, this serum-free cell culture medium produces robust cultures with features of a naïve-like state, such as tightly packed, domed colonies with refractive edges. Human ES/iPS cells cultured in RSeT™ Feeder-Free Medium show increased expression of key transcripts associated with the naïve-like state, such as KLF17, KLF2, KLF4, and TFCP2L1, and can either be differentiated or converted back to a primed state by culture in mTeSR™1 and then differentiated.
Compatible products that can be used for differentiation include STEMdiff™ Definitive Endoderm Kit (Catalog #05110), STEMdiff™ SMADi Neural Induction Kit (Catalog #08581), and STEMdiff™ Mesoderm Induction Medium (Catalog #05220).
Data Figures
Figure 1. Schematic of Reversion of Primed to Naïve-Like hPSCs with RSeT™ Feeder-Free
Primed hPSCs are plated as aggregates in mTeSR™1. On day 1, mTeSR™1 is replaced with RSeT™ Feeder-Free, the cultures are transferred to hypoxic conditions, and the medium is exchanged every other day. By day 4 or 5, the colonies are generally large enough to be passaged. During the initial culture in RSeT™ Feeder-Free, colonies expand and begin to adopt a tightly-packed, highly domed morphology characteristic of naïve-like stem cells with smooth and refractive colony edges as early as passage 1.
Figure 2. hPSCs Maintained in RSeT™ Feeder-Free are Reverted to a Naïve-Like State and Express High Levels of Naïve-Associated Genes
(A) A representative image of hPSCs that reverted to a naïve-like state after being cultured in RSeT™ Feeder-Free for 1 passage. During reversion, colonies change from a flat morphology to a domed morphology characteristic of naïve-state hPSCs. (B) Expression of naïve-associated genes (KLF2, KLF4, KLF17, TFCP2L1, STELLA, and DNMT3L) in hPSCs that were reverted to a naïve-like state in RSeT™ Feeder-Free. Expression levels were measured by qPCR and normalized to levels in primed hPSCs.
