Isolation and Culture of Fibroblasts

Check if the same lab product or an alternative is used in the 5 most similar protocols
All patient-derived fibroblasts were collected with informed written consent from each patient in compliance with the Declaration of Helsinki and the experiments conformed to the principles set out in the Department of Health and Human Services Belmont Report. RDEB patient samples are usually donations from biopsy sites, either of non-SCC or SCC origin, and the non-EB patient samples are from breast reduction skin donations from elective surgeries. Cells were isolated from skin biopsies taken from routine or tumor excision surgeries and cultured at 37 °C at 5% CO2. Primary fibroblasts were grown in Dulbecco’s modified essential medium (DMEM, Corning Cellgro, Mediatech Inc, Manassas, VA) with 10% fetal bovine serum (FBS, PEAK Serum, Cat PS-FB1, Colorado, USA) and 1% Penicillin Streptomycin 100X Solution (Corning, Cat 30-002-CI, Manassas, VA, USA). All media in experimental conditions contained l-ascorbic acid (150 μM, Wako, 012-12061). Non-EB and RDEB fibroblasts (Appendix Table S3) were used up to passage 7. Fibroblasts were plated in 6-well plates to achieve 100% confluence within 2 days of seeding, followed by protein extraction or RNA isolation.

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.
