The absence of morphological proof of cell aging (distended or irregular flat cell shapes and more circumscribed nuclei under phase contrast microscopy), neither SJL-AdMSCs nor C57-AdMSCs undergo senescence phenomena in the highest passages evaluated. Our outcomes are in agreement with prior research in which they have maintained a prolonged in vitro expansion of murine MSCs, postulating that these cells, offered the acceptable situations, will remain and proliferate in culture with no decreasing their growth rate [13,19,22]. Even so, although we find no proof of senescence or slowing of growth with time, we can’t exclude that various experimental approaches could further influence their behavior. Preceding functions have hence reported evidence of senescent options beneath particular situations that is, enlarged and irregular cell shapes and eventually a cease of proliferation demonstrating that many relevant aspects play a crucial role in MSC expansion, which include different culture occasions and circumstances, the tissue source from which MSCs are obtained, cell isolation protocols or cell density of the beginning culture [14-17,19,22].Marin-Ba sco et al.
