Murine and Human MSCs CCR7 Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Murine MSCs derived from compact bone at passage 4 were collected for murine CCR7 detection. Splenic cells (SPC) from the same species served as positive controls. Human MSCs derived from bone marrow (hBM-MSCs, Cyagen) or umbilical cord (hUC-MSCs, Cyagen) at passage 5 were obtained for human CCR7 expression analysis. Human peripheral blood cells (hPBC) were served as positive control. The specific PCR primers were listed as followed. Murine CCR7: 5′-CAGCCTTCCTGTGTGATTTC-3′ (forward), 5′-TGGGAGAGGTCCTTGTAGTC-3′ (Reverse); Human CCR7: 5′-CCAGACAGGGGTAGTGCGAG-3′(Forward), 5′-AGGCAGAAGAGTCGCCTATG-3′ (Reverse); Murine GAPDH: 5′-GGAGCGAGACCCCACTAACA-3′ (Forward), 5′-ACATACTCAGCACCGGCCTC-3′ (Reverse); Human GAPDH: 5′-ATGGGGAAGGTGAAGGTCGGAGTCAA-3′ (Forward), 5′-CGGAGGGGCCATCCACAGTCTTCT-3′ (Forward). RT-PCR was performed as described by the manufacture (TOYOBO).

Human bone marrow-derived mesenchymal stem cells (hBMMSCs) and mouse BMMSCs were purchased from Cyagen Biosciences Co., Ltd (Guangzhou, China). Mouse macrophage cell line RAW264.7, mouse keratinocyte cell line JB6, human macrophage cell line THP-1 and human epithelial cell line HaCaT cell line were purchased from Beina Biotechnology Co., Ltd (Guangzhou, China). All cells were maintained following the company’s instructions. For in vitro activation, RAW264.7 cells were treated with 1 µg/mL LPS (Sigma-Aldrich) and 20 ng/mL IFN-γ (Sigma-Aldrich) for 12 h. THP-1 cells were treated with 1 µg/mL LPS (Sigma-Aldrich) and 20 ng/mL hIFN-γ (Sigma-Aldrich) for 24 h after pre-treatment with 200 ng/mL Phorbol-12-myristate-13-acetate (PMA) (Sigma-Aldrich) for 6 h.

Murine Macrophages and Human MSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
The murine-derived macrophage cell line RAW 264.7 cells (RAW cells, Cell Bank, purchased from the Chinese Academy of Sciences) and human bone marrow mesenchymal stem cells (hBMMSCs) were purchased from Cyagen Biosciences Inc. (Guangzhou, China). The RAW 264.7 cells were cultured using the Dulbecco’s modified Eagle’s medium (DMEM, Gibco) supplemented with 10% (v/v) fetal bovine serum (FBS, Gibco) and antibiotics (100 U/ml of penicillin and 100 mg/ml of streptomycin) (Thermo Fisher Scientific, United States). The hBMMSCs were cultured using Minimal Essential Medium Alpha (α-MEM, Gibco) supplemented with 10% (v/v) FBS and antibiotics (100 U/ml of penicillin and 100 mg/ml of streptomycin).

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.
