Commercially available primary hCF isolated from right ventricles of human male donors (age 39–42 years) (CC-2904, Lonza, Walkersville, MD, USA) was expanded in complete FGM-3 medium (Lonza) to passage P3 and routinely cultured between passages P3-P5 in medium consisting of 45% Dulbecco’s modified Eagle’s medium (DMEM), 45% F12 (Gibco Invitrogen, Burlington, ON, Canada), 10% fetal calf serum (Invitrogen), 1000 U/mL penicillin/streptomycin (Invitrogen), and fibroblast growth supplement (ScienCell, Carlsbad, CA, USA). Rat embryonic fibroblasts (REF) and human MRC-5 cells were used for selected experiments and cultured in Dulbecco’s modified Eagle’s medium (DMEM), 10% fetal calf serum (Gibco), 1000 U/mL penicillin/streptomycin (Invitrogen). Soft silicone culture substrates (ExCellness Biotech, Lausanne, Switzerland) were used to mimic the elastic range of healthy and diseased tissue and to control myofibroblast activation. We selected 3 kPa soft, 26 kPa medium-stiff, and 65 kPa stiff substrates to model increasing severity of fibrotic scar stiffening [38 (link)]. Silicone culture substrates were oxygen plasma-treated and coated with 2 μg/cm2 fibronectin (Millipore, Billerica, MA, USA) to promote cell attachment [39 (link)].

Endometrial samples were obtained from 5 young women (24-32 years old) undergoing oocyte donation. The biopsies were collected after each patient in accordance with the requirements of the Ethical Committee of Cruces Hospital signed informed consent. Endometrial tissue was rinsed with phosphate-buffered saline (PBS) supplemented with antibiotics and minced into 1-2 mm 3 pieces. The fragments were digested with 0.3% collagenase II (Gibco Life Technologies, Gaithersburg, MD, USA) in fibroblast medium (FM, ScienCell Research Laboratories, San Diego, CA, USA) with antibiotics at 37 8C. The resulting cell suspension was seeded into culture flasks and maintained with FM supplemented with Fibroblast Growth Supplement, 2% fetal bovine serum (FBS) and antibiotics (penicillin/streptomycin) (termed complete FM) (ScienCell Research Laboratories, San Diego, CA, USA) in a humidified atmosphere at 37 8C with 5% CO 2 .

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.
