(A) Overview of a previously explained micro-patterning centered hPSC differentiation assay [30] using OCT4 and SOX2 manifestation levels as signals of early fate choices to compare PEG and CP plates. (B) Quantified compartments of early fate choices as defined in panel A, in both PEG and CP plates. The press conditions tested were NSCNutristem, Apel (vehicle for the following), BMP (BMP4), BA (BMP4+ActivinA), FSB (bFGF+SB431542; observe Materials and methods for concentration details). Data displayed as mean (+ SD) of 4 self-employed replicates. The fate choice reactions of hPSCs on both the plates were highly correlated (R2 0.9). (C) Representative immunofluorescent pictures of hPSC colonies stained for OCT4 and SOX2 in the various media conditions examined. Scale bars suggest 500 m.

Each dot represents the amount of colonies discovered per well for 120 arbitrarily chosen wells between your 4 replicates of PEG versus CP plates. Variety of cells discovered per colony between PEG and CP plates. Each dot represents the common variety of cells per colony for 120 arbitrarily chosen wells between your 4 replicates of PEG Lenalidomide-C5-NH2 versus CP plates.

(E) FACS plots showing the effectiveness of induction of pancreatic progenitors as indicated from the manifestation of PDX1 and NKX6.1 for candidate hPSC lines from your Strong and Weak clusters from panel A. The differentiation was performed using a previously explained protocol [77]. The data are from 3 self-employed wells; the experiment was performed twice. The gating was performed using the cells stained with only the secondary antibodies (demonstrated in blue). The samples stained for PDX1 and NKX6.1 are.
