Study TitleStirred suspension bioreactors maintain naïve pluripotency of human pluripotent stem cells (hPSCs)
Study SummaryAlthough cell therapies require large numbers of quality-controlled hPSCs, existing technologies are limited in their ability to efficiently grow and scale stem cells. We report here that cell-state conversion from primed-to-naïve pluripotency enhances the biomanufacturing of hPSCs. Naïve hPSCs exhibit superior growth kinetics and aggregate formation characteristics in stirred suspension bioreactors compared to their primed counterparts. Moreover, we demonstrate the role of the bioreactor mechanical environment in the maintenance of naïve pluripotency, through transcriptomic enrichment of mechano-sensing signaling for cells in the bioreactor along with a decrease in expression of lineage-specific and primed pluripotency hallmarks. Bioreactor-cultured, naïve hPSCs express epigenetic regulatory transcripts associated with naïve pluripotency, and display hallmarks of X-chromosome reactivation. They exhibit robust production of naïve pluripotency metabolites and display reduced expression of primed pluripotency cell surface markers. We also show that these cells retain the ability to undergo targeted differentiation into beating cardiomyocytes, hepatocytes, and neural rosettes. They additionally display faster kinetics of teratoma formation compared to their primed counterparts. Naïve bioreactor hPSCs also retain structurally stable chromosomes. Our research corroborates that converting hPSCs to the naïve state enhances hPSC manufacturing and indicates a potentially important role for the bioreactor’s mechanical environment in maintaining naïve pluripotency.

Collection:

Collection ID:CO001446
Collection Summary:Extracellular metabolite dynamics was analyzed during primed to naïve conversion in the bioreactor. For this, the media of H1 hESCs in the bioreactor was gradually switched from mTESR1 to RSeT media within 6 days of culture (D2 to D6) and the media was collected every day for the analysis. For H9 hESCs, the extracellular metabolites were analyzed in the spent media of primed and established naïve (P5) hPSCs in the bioreactor, and the media of each primed or naïve hPSCs was collected at day four of bioreactor culture.
Sample Type:Stem cells

For this, the media of H1 hESCs in the bioreactor was gradually switched from mTESR1 to RSeT media within 6 days of culture (D2 to D6) and the media was collected every day for the analysis.

Sample Preparation:

Sampleprep ID:SP001459
Sampleprep Summary:The metabolite extraction was started using LC-MS or HPLC grade methanol (Sigma-Aldrich, 1.06035). Briefly, a 950 μL of pre-chilled 50% MeOH/H2O was added to a 50 μL of the bioreactor-collected media (making a D20 dilution), and the samples were incubated on ice for 30 min to allow for full extraction. Macromolecules were then pelleted by centrifugation at max speed (~18,000-21,000 g) for 10 mins in a bench top centrifuge (preferably chilled) to extract the supernatant. Further, the extracted samples were stored in -80 prior to running HPLC-MS.
