Cultivation of Human Coronary Artery Smooth Muscle Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human coronary artery smooth muscle cells (HCASMCs) from three donors were procured from GIBCO (Life Technologies, CA, USA) and LONZA (Walkersville MD, USA). The cells were pre-characterized for smooth muscle cell specific markers and for their compatible (<5% variation ) growth response to fetal calf serum (FCS; 2.5%). Cells were cultured in M231 culture medium containing smooth muscle growth supplement (Life Technologies, CA, USA) and under standard tissue culture conditions as described previously43 (link). HCASMCs in 3rd to 5th passage were used for the growth and molecular assays.

Primary human aortic smooth muscle cells were purchased from the American Type Culture Collection (ATCC; PCS-100-012) and cultured in Medium 231 (Life Technologies), 500 ml of which was supplemented with 25 ml of growth supplement (smooth muscle growth supplement; Life Technologies) and sodium l-ascorbate (50 μg/ml; Sigma-Aldrich) for extracellular matrix secretion. The cells were seeded at a density of 1.25 × 104 per ml and used within the first three passages. The glass and PDMS surfaces were coated with collagen before seeding. The PDMS surfaces were oxygen plasma cleaned at 200 W for 10 min immediately before seeding collagen to make the surface hydrophilic.

Check if the same lab product or an alternative is used in the 5 most similar protocols
PAH PASMC were isolated from PAH patients. Normal PASMC were isolated from control subjects or purchased from Lonza or Cell Applications Inc. PASMC lines were studied within 6 passages. PASMC were grown in Medium 231 supplemented with Smooth Muscle Growth Supplement (SMGS, Life Technologies, Carlsbad, CA, USA). Experiments were performed on 6 normal PASMC lines (50% Female, Mean age: 50.7 years) and 8 PAH PASMC lines (28% Female, Mean age: 41.2 years). Blood Outgrowth Endothelial Cells (BOEC) were isolated and cultured from PAH patients and normal individuals (Demographics in Supplementary Table 1) as previously described20 (link). Briefly blood was collected from normal individuals (n=5) and PAH patients (n=6) by venipuncture. Peripheral blood mononuclear cell (PBMC) was isolated from the whole blood by density gradient centrifugation. PBMC were cultured in BOEC generation medium for 7–14 days for the appearance of outgrowth colonies.

Aortic SMCs Characterization Protocols

Aortic SMCs were derived from the ASC of 16‐week‐old Fbn1C1039G/+ male and female mice, as previously described.18 Medium 231 and smooth muscle growth supplement were purchased from Life Technologies (Foster City, CA). SMC (2.0×105 cells/mL) were cultured to confluence in SMC media and starved with serum‐free medium for 24 hours before the treatment. SMC were treated with either dihydrotestosterone (DHT) (10 nmol/L) (Sigma‐Aldrich), flutamide (1 μmol/L) (Selleckchem, Houston, TX), mouse recombinant TGF‐β (5 ng/mL) (R&D Systems, Minneapolis, MN), or vehicle control for 24 hours for p‐ERK1/2 protein assay, 48 hours for MMP activity assay and 24 and 48 hours for androgen receptor protein assay. For p‐Smad2 protein assay, SMC were treated with mouse recombinant TGF‐β (5 ng/mL) or vehicle control for 1 hour after pretreatment with DHT, flutamide, or vehicle control for 24 hours. When applicable, flutamide was added into the media 3 hours before DHT treatment to block androgen receptor activation. Experiments included n=5 to 6 per group.

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.
