Human fibroblast cells from HGPS patients (AG03198, 10-year-old female; AG03199, 10-year-old female; AG11513, 8-year-old female; AG11498, 14-year-old male), and normal person (GM00038, 9-year-old female N9) were obtained from Coriell Cell Repositories (Camden, NJ, USA) and maintained in Eagle’s minimal essential medium supplemented with 15% fetal bovine serum, and 2 mM glutamine without antibiotics. HEK293 cells were obtained from the American Type Culture Collection (ATCC, Manassas, VA, USA) and maintained in liquid medium containing 10% FBS, and 1% penicillin–streptomycin at 37 °C with 5% CO2.

Primary human fibroblast cells from HGPS patients (AG03198, 10-year-old female, HGPS1; AG11513, 8-year-old female, HGPS2; AG11498, 14-year-old male, HGPS3), WRN patients (AG06300, 37-year-old male, WRN1; AG05229, 25-year-old male, WRN2; AG03141, 30-year-old female, WRN3) and unaffected controls (GM00038, 9-year-old female, N9; AG09603, 81-year-old female, N81) were obtained from Coriell Cell Repositories (Camden, NJ, USA) and maintained in Eagle’s Minimal Essential Medium (EMEM) supplemented with 15% fetal bovine serum (FBS) and 2 mM glutamine or in EMEM with 26 mM HEPES without antibiotics. HEK293 cells were obtained from the American Type Culture Collection (ATCC, Manassas, VA, USA) and maintained in liquid medium (DMEM) containing 10% FBS and 1% penicillin–streptomycin at 37 °C with 5% CO2. All cell lines were established in our laboratory under study protocols approved by the PNU IRB, in accordance with relevant guidelines and regulations.

Fibroblast Reprogramming to iPSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human fibroblasts from three apparently healthy individuals (GM00038, GM08680, GM05756) were purchased from Coriell. Reprogramming was performed using the CytoTune-iPS 2.0 Sendai reprogramming kit according to the manufacturer’s instructions (Thermo Fisher Scientific). Briefly, fibroblasts were plated at 20,000 cells/cm2 (link) and cultured until they were 30–60% confluent. Cells were transduced with the Sendai reprogramming vectors at an MOI of 5:5:3 (KOS:hc-Myc:hKlf4). Cells were maintained in fibroblast media until passaged onto VN-coated plates on day 7. On day 8, medium was changed to E8 Medium and cells were cultured for additional 20 days. On day 28, colonies were picked using a 25-gauge needle to cut single colonies into 6–8 pieces and transferred onto VN-coated plates containing E8 Medium only or supplemented with Y-27632 or CEPT for 48 h. After 48 h, cells were kept in E8 Medium only. Confluency was assessed 8 days after colony picking using the Celigo Imaging Cytometer (Nexcelom Biosciences).

Fibroblast Culturing Protocol for Research

Check if the same lab product or an alternative is used in the 5 most similar protocols
Primary fibroblasts derived from healthy controls (GM00038 and GM09503) were obtained from Coriell Institute for Medical Research (Camden, NJ). Each SWS-derived fibroblast line was obtained by the referring clinician and grown via a clinical lab service and then sent to us with consent through an approved IRB (Ferreira et al., 2018 (link)). SW1353 was obtained from ATCC.
Fibroblasts and SW1353 were cultured in Dulbecco’s Modified Eagle’s medium (DMEM) containing 1 g/L glucose supplemented with 10% heat-inactivated fetal bovine serum (FBS), 1X Penicillin-Streptomycin (Corning) and 200 mm L-glutamine (Corning). HEK293T cells were cultured in 4.5 g/L glucose DMEM supplemented with the same components as mentioned above.

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.
