NIH/3 T3 cells were seeded into a 24-well plate in growth medium on cover glasses (Marienfeld). 24 h later Bmpr1b expression vectors were transfected into the NIH/3 T3 cells using Lipofectamine 2000 (Invitrogen, Life Technologies) following the manufacturer´s instructions. Another 24 h later cells were incubated under serum free conditions (DMEM 4.5 g/l glucose (Lonza), 2 mM L-glutamine (Lonza)) for 1 h, subsequently fixed with 4 % paraformaldehyde in PBS and blocked in PBS containing 10 % FBS superior (Biochrom) over night. Non-permeated cells were incubated with a rabbit anti-HA antibody (H6908, Sigma-Aldrich; diluted 1:100 in PBS containing 10 % FBS superior (Biochrom)) for 1 h. After washing with PBS the cells were incubated with the secondary antibody anti-rabbit-Alexa Fluor 488 (A11008, Molecular Probes Life Technologies) and with DAPI (Invitrogen, Life Technologies) for 1 h. The cover glasses containing stained cells were mounted on microscope slides (‘SuperFrost Plus’, Menzel) using Fluoromount-G (Southern Biotech).

Isolation and Culture of Human Oral Fibroblasts

Check if the same lab product or an alternative is used in the 5 most similar protocols
The normal human oral fibroblast line NHOF-1 fibroblast cells were obtained from a buccal mucosa biopsy, under ethical approval of the Dental Teaching Hospital, Peradeniya, Sri Lanka, following informed patient consent (Ethical Clearance Certificate No. FDS-ERC/2008/02/TIL) [23] . The NHOF-1 were tested for mycoplasma following isolation with the MycoplsmaAlert ® (Lonza, Switzerland) and found to be negative, and re-tested at the time of use. The cells were cultured and maintained at 37 o C in a humidified atmosphere of 10% CO2/90% air in Dulbecco's Modified Eagle's Medium (DMEM), 4.5g/l glucose (Lonza) supplemented with 10% vol/vol hyclone II fetal bovine serum (FBS -Thermoscientific), penicillin, streptomycin 50units/ml (Life Technologies) and 2mM glutamine (Life Technologies).
Cells were sub-cultured and prepared for experiments by washing once with 0.02% EDTA (ethylenediaminetetraacetic acid) in calcium-and magnesium-free phosphate buffered saline (PBS) and then incubating with 0.01% trypsin/0.01% EDTA in PBS at 37 o C, until the cells detached. Following this, the trypsin/EDTA mixture was neutralized with three times the volume of DMEM/FBS medium, and the cells counted in a haemocytometer prior to resuspension, dilution and plating for the experiments.
Cells were seeded in a 96 well plate at a density of 9.32 x 10 3 /cm 2 in each well.

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.
