“…However, FBS has many disadvantages, such as batch-to-batch variation, xenoimmunisation and zoonotic transmission of infectious agents, and may therefore affect the outcome of experiments and ultimately render the cell product unacceptable for clinical use from a safety perspective (1,5,9,(29)(30)(31)(32)(33)(34). Before ASCs can be used in the clinical setting, GMP-compliant standardised operating procedures as well as isolation and expansion protocols need to be in place (9,24). One of the key adjustments that need to be made during the transition from the research to the clinical setting is the replacement of FBS with alternatives that adhere to GMP standards, such as human-derived alternatives.…”

“…One PC unit is comprised of four buffy coat (BC) units (the white blood cell and platelet fraction obtained following centrifugation), and is resuspended in either one unit of platelet-rich plasma or another additive solution (22,23). Expired PCs, which are usually discarded by blood banks after 4 or 5 days, can also be used to manufacture HPL, although there are very few reports on the use of expired PC products for the expansion of ASCs (19,24). In this study, we have investigated the effects that different pHPL alternatives (fresh versus expired BCs resuspended in either platelet-rich plasma or an additive solution), produced using quality controlled manufacturing protocols, have on ASC proliferation, morphology and immunophenotype.…”

“…Ein weiteres klinisches Einsatzgebiet von MSCs basiert auf der Beobachtung, dass MSCs eine Reihe immunmodulatorischer Faktoren absondern und immunsuppressive Eigenschaften aufweisen (Le Blanc et al, 2003 (Bieback et al, 2009;Bieback et al, 2012a Eine in der ES-Zellforschung verbreitete Auffassung besteht dabei darin, dass die beiden zentralen Pluripotenzfaktoren Oct4 13 und Sox2 14 den undifferenzierten pluripotenten Zustand von Zellen aufrechterhalten und somit ihre Differenzierung verhindern (Hanna et al, 2010b;Young, 2011). Allerdings ist mit diesem Modell das Ende der Pluripotenz und der Beginn der Differenzierung mechanistisch nur schwer zu erklären, da die (positiven) Regelkreise der beiden Faktoren eng miteinander verzahnt sind.…”

“…6,[11][12][13][14] In addition to the in vitro manipulation procedures, the original properties of the donor, such as the inherent and acquired factors (eg, age, sex, tissue, and underlying physiology or pathology), are contributed to the variance of mesenchymal stem cell (MSC) proliferation capacity and differentiation potency. [15][16][17][18] Therefore, it is important to establish assessing parameters for evaluating the long-term proliferation potency of ADSCs, especially in the case of quality control of large-scale cell manufacturing procedures.…”
