Lentiviral-mediated Modulation of H19 and miR-140-5p in hDPSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Recombinant lentiviruses targeting H19 (shH19-1 and shH19-2) and Lenti-shNC were purchased from GenePharma Company (Shanghai, China). hDPSCs were transfected by lentiviruses exposure in 1 mL α-MEM supplemented with 10% FBS and 5 μg/mL polybrene for 24 h. H19 overexpression plasmid pcDNA3.1-H19, miR-140-5p mimics, and scramble control (NC) were chemically synthesized by GenePharma. When hDPSCs were 70–80% confluent, pcDNA-H19 and miRNA mimic transfection was performed using Lipofectamine 3000 (Invitrogen, USA) according to the manufacturer’s instructions. qRT-PCR analysis was used to detect H19 and miR-140-5p expression levels to validate the transfection efficiencies. The cells were cultured in mineralizing medium for odontoblastic differentiation 48 h after transfection.

Recombinant lentiviruses containing full-length H19 (Gene Bank accession number, NR_002196.1) and scramble control (NC) were obtained from GenePharma Company (Shanghai, China). Recombinant lentiviruses targeting H19 (Lenti-shH19-1 and Lenti-shH19-2) and scramble control (Lenti-shNC) were also obtained from GenePharma Company. SCAPs were transfected by lentiviruses exposure in 1 mL α-MEM supplemented with 10% FBS and 8 μg /mL polybrene (POL) for 10 h. Infected cells were cultured in the conventional medium and the expression level of H19 was detected.

Lentivirus-Mediated Gene Modulation in HAMSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Recombinant lentiviruses containing full-length H19 (Gene Bank accession number, NR_002196.1) and scramble control (NC) were obtained from Integrated Biotech Solutions Company (Shanghai, China) and were named Lenti-H19 and Lenti-NC. Recombinant lentiviruses targeting H19 and scramble control named Lenti-shH19 and Lenti-shNC, respectively, were obtained from GenePharma Company (Shanghai, China). All lentivirus vectors contained the green fluorescent reporter gene (GFP). The viruses were used to infect HAMSCs and establish stably expressing transfectants. HAMSCs were exposed to viral supernatant containing 1 mL DMEM supplemented with 10% FBS and 8 μg /mL polybrene (POL) for 10 h.

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.
