Abstract
The study of proliferation regulation in human pluripotent stem cells is crucial to gain insights into understanding the physiology of these cells. However, redox regulation of the pluripotent cell cycle remains largely unexplored. Here, using human embryonic stem cells (hESCs) as well as human induced pluripotent stem cells (hiPSCs), we demonstrate that the level of reactive oxygen species (ROS) in pluripotent cells oscillates in accordance with the cell cycle progression with the peak occurring at transition from S to G2 /M phase of the cycle. A decrease of this level by antioxidants leads to hindered S-phase initiation and progression but does not affect the early-G1 -phase or mitosis. Cells exposed to antioxidants in the early-G1 -phase accumulate the phosphorylated retinoblastoma protein and overcome the restriction point but are unable to accumulate the main regulators of the S phase-CYCLIN A and GEMININ. Based on the previous findings that CYCLIN A stability is affected by redox homeostasis disturbances in somatic cells, we compared the responses to antioxidant treatments in hESCs and in their differentiated fibroblast-like progeny cells (difESCs). In difESCs, similar to hESCs, a decrease in ROS level results in the disruption of S-phase initiation accompanied by a deficiency of the CYCLIN A level. Moreover, in antioxidant-treated cells, we revealed the accumulation of DNA breaks, which was accompanied by activation of the apoptosis program in pluripotent cells. Thus, we conclude that maintaining the physiological ROS level is essential for promotion of proliferation and accurate DNA synthesis in pluripotent cells and their differentiated descendants.

Abstract
Mesenchymal stromal cells (MSCs) are heterogeneous and contain several populations, including stem cells. MSCs' secretome has the ability to induce proliferation, differentiation, chemo-attraction, anti-apoptosis, and immunomodulation activities in stem cells. Moreover, these cells recognize tissue damage caused by drugs, radiation (e.g., Ultraviolet, infra-red) and oxidative stress, and respond in two ways: either MSCs differentiate into particular cell lineages to preserve tissue homeostasis, or they release a regenerative secretome to activate tissue repairing mechanisms. The maintenance of MSCs in quiescence can increase the incidence and accumulation of various forms of genomic modifications, particularly upon environmental insults. Thus, dysregulated DNA repair pathways can predispose MSCs to senescence or apoptosis, reducing their stemness and self-renewal properties. For instance, DNA damage can impair telomere replication, activating DNA damage checkpoints to maintain MSC function. In this review, we aim to summarize the role of DNA damage and associated repair responses in MSC senescence, differentiation and programmed cell death.

Abstract
Temporal dependence of changes in the morphological characteristics of cells of two cultured lines of cancer origin, HeLa and A549, induced by photodynamic treatment with Radachlorin photosensitizer, have been monitored using digital holographic microscopy during first two hours after short-term irradiation. The observed post-treatment early dynamics of the phase shift in the transmitted wavefront indicated several distinct scenarios of cell behavior depending upon the irradiation dose. In particular the phase shift increased at low doses, which can be associated with apoptosis, while at high doses it decreased, which can be associated with necrosis. As shown, the two cell types responded differently to similar irradiation doses. Although the sequence of death scenarios with the increase of the irradiation dose was the same, each scenario was realized at substantially different doses. These findings suggest that the average phase shift of the transmitted wavefront can be used for quantitative non-invasive cell death characterization. The conclusions made were cofirmed by commonly used test assays using confocal fluorescent microscopy.

Abstract
Stress-induced premature senescence program is known to be activated in cells by various genotoxic stressors, and oxidative stress is considered to be the main of those. To this end, many studies discover antioxidants as protective anti-aging agents. In the current study, we examined the effects of different antioxidants (Tempol, resveratrol, NAC, DPI) on the mesenchymal stem cells maintained in normal physiological conditions. We used high, but non-cytotoxic antioxidant doses which are widely used in laboratory practice to protect cells from oxidative damage. We show that these substances induce reversible block of cell proliferation and do not cause any genotoxic effects when applied to the quiescent cells. However, the same doses of the same substances, when applied to the proliferating cells, can induce irreversible cell cycle arrest, DNA strand breaks accumulation and DNA damage response activation. As a consequence, antioxidant-induced DNA damage results in the stress-induced premature senescence program activation. We conclude that high doses of antioxidants, when applied to the proliferating cells that maintain physiological levels of reactive oxygen species, can cause DNA damage and induce premature senescence which suggests to re-estimate believed unconditional anti-aging antioxidant properties.

Abstract
Previously we demonstrated that endometrium-derived human mesenchymal stem cells (hMESCs) via activation of the ATM/p53/p21/Rb pathway enter the premature senescence in response to oxidative stress. Down regulation effects of the key components of this signaling pathway, particularly ATM and p53, on a fate of stressed hMESCs have not yet been investigated. In the present study by using the specific inhibitors Ku55933 and Pifithrin-α, we confirmed implication of both ATM and p53 in H(2)O(2)-induced senescence of hMESCs. ATM or p53 down regulation was shown to modulate differently the cellular fate of H(2)O(2)-treated hMESCs. ATM inhibition allowed H(2)O(2)-stimulated hMESCs to escape the permanent cell cycle arrest due to loss of the functional ATM/p53/p21/Rb pathway, and induced bypass of mitosis and re-entry into S phase, resulting in tetraploid cells. On the contrary, suppression of the p53 transcriptional activity caused a pronounced cell death of H(2)O(2)-treated hMESCs via autophagy induction. The obtained data clearly demonstrate that down regulation of ATM or p53 shifts senescence of human endometrial stem cells toward tetraploidization or autophagy.

Abstract
Human endometrium-derived mesenchymal stem cells (hMESCs) enter the premature senescence under sublethal oxidative stress, however underlying mechanism remains unknown. Here, we showed that exogenous H2O2 induces a rapid phosphorylation and co-localization of ATM, H2A.X, 53BP1 leading to DNA damage response (DDR) activation. DDR was accompanied with nuclear translocation of p-p53 followed by up-regulation of p21Waf1 and the permanent hypophosphorylation of pRb. Additionally, the increased p38MAPK/MAPKAPK-2 activation persisted in H2O2-treated cells. We suggest that both p53/p21/pRb and p38MAPK/MAPKAPK-2 pathways are responsible for establishing an irreversible cell cycle arrest that is typical of senescence. The process of further stabilization of senescence required prolonged DDR signaling activation that was provided by the permanent ROS production which in turn was regulated by both p38MAPK and the increased functional mitochondria. To reverse senescence, the pharmacological inhibition of p38MAPK was performed. Cell treatment with SB203580 was sufficient to recover partially senescence phenotype, to block the ROS elevation, to decrease the mitochondrial function, and finally to rescue proliferation. Thus, suppression of the p38MAPK pathway resulted in a partial prevention of H2O2-induced senescence of hMESCs. The current study is the first to reveal the molecular mechanism of the premature senescence of hMESCs in response to oxidative stress.
