On predetermined days, hydrogels containing encapsulated PSCs were collected, placed in DNase/Rnase-free microtubes, and flash frozen using liquid nitrogen. Samples were then stored at −80°C until use. To extract RNA, frozen gels were homogenized in 600 µL of lysis buffer (NucleoSpin RNA II kit, Clontech) and were subjected to two additional cycles of freeze-thaw in order to lyse cells. Lysates were purified using NucleoSpin Filters. Following purification, 600 µL of Rnase-free 70% ethanol was added to the lysates and mixed thoroughly. The mixtures were then transferred to NucleoSpin RNA columns for RNA extraction following manufacturer’s protocol. Using 30 µL of Dnase/Rnase-free water, the isolated RNAs were eluted and then quantified by UV spectrometry (NanoDrop 2000, Thermo Scientific). Using PrimeScript RT reagent kit (Clontech) the total isolated RNA were converted into single-stranded cDNA. Gene expression level was assessed by quantitative real-time PCR and analyzed following a published protocol. Real-time PCR primer sequences can be found listed in Table S1.

Samples of cell-laden hydrogels were collected in DNase/RNase-free microtubes, flash-frozen in liquid nitrogen and stored in −80°C. Tota l RNA was isolated from the encapsulated cells with NucleoSpin RNA II kit (Clontech). The concentration and purity of RNA were obtained by NanoDrop 2000 Spectrophotometer (Thermo Scientific). Next, purified RNA samples were converted into complementary DNA (cDNA) with PrimeScript RT Reagent Kit (Clontech, TaKaRa). For Taqman® array experiments, only samples with concentration greater than 100 ng/mL, 260/280 > 2.0, 260/230 > 1.8 were used. cDNA samples were diluted to 100 ng/mL and mixed with same volume of Taqman® fast universal master mix. For 96 well TaqMan® Array Gene Signature Sets, 10 μl mixture was deposited in each well and detected by Applied Biosystems 7500 Fast Real-Time PCR machine. Three biological replicas were used for each experimental condition. Additional qPCR on EMT-related genes was performed using cDNA and SYBR Premix Ex TaqII kit (Clontech) with appropriate primers as listed in Table S1. The relative gene expression levels were analyzed by the 2−ΔΔCT method with GAPDH as the internal control (i.e., housekeeping gene) and the expression level of respective gene in the control group (i.e., Gel/PEG gel with no HA and no stiffening) as the external control.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
