WebJan 1, 2013 · The first passage of initial colonies should be performed after about 7–10 days. It is important to always determine the number of cells harvested per passage and to define the seeding density to calculate the population doublings for each passage (PDP) and accordingly the cumulative population doublings throughout culture expansion … WebAbstract Rates of protein turnover have been measured in three normal and three Duchenne muscular dystrophy (DMD) skin fibroblast cell lines. Cell populations were analyzed at identical states with regard to cell number, state of topoinhibition, and cumulative population doublings (CPD).

WebFeb 15, 2011 · The clones and h-hAMCs successfully proliferated while demonstrating different cumulative population doublings (CPD) during an 80-day culture. In addition, the colony-forming efficiency (CFE) of h-hAMCs was significantly lower than those of 8B and 11F and higher than that of 11D. Clones 8B and 11F were tripotent, whereas 11D did not … WebJun 13, 2024 · We collected HLA-DR values from the two passages required in the production process, which typically take a total of 3 weeks and correspond to 24.6 ± 1.5 cumulative population doublings (CPD). We observed a decrement in HLA-DR positivity of at least 25% in 71.9% of the cultures, whereas only 5.3% increased HLA-DR more … WebMar 9, 2024 · At passage 3, the cumulative population doublings (cPD) of BM-MSCs were 6 ± 0.5, while in AT-MSCs and WJ-MSCs this parameter was significantly higher and reached 9.6 ± 0.4 and 12.3 ± 0.7,... cryptand 221
