Check if the same lab product or an alternative is used in the 5 most similar protocols
hASCs and hBMMSCs were seeded on different surfaces as described above, in 6-well plates. After 7 and 14 days of osteoinduction, the Trizol reagent (Invitrogen, Carlsbad, CA, USA) was used to isolate the total cellular RNAs of each group. After synthesizing the first strand cDNA using the reverse transcription system (Roche, Basel, Switzerland), quantification of all gene transcripts was performed by real-time polymerase chain reaction (qPCR) using a Power SYBR Green PCR Master Mix and an ABI PRISM 7500 sequence detection system (Applied Biosystems, Foster City, CA, USA). The β-actin expression was used as the internal control. The primer sequences were shown in Table 1. The cycle threshold values (Ct values) were used to calculate the fold differences among the samples, using the ∆∆Ct method65 (link),66 (link).

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.
