    Abstract Each cell is equipped with a conserved housekeeping mechanism, known as autophagy, to recycle exhausted materials and dispose of injured organelles via lysosomal degradation. Autophagy is an early-stage cellular response to stress stimuli in both physiological and pathological situations. It is thought that the promotion of autophagy flux prevents host cells from subsequent injuries by removing damaged organelles and misfolded proteins. As a correlate, the modulation of autophagy is suggested as a therapeutic approach in diverse pathological conditions. Accumulated evidence suggests that intermittent fasting or calorie restriction can lead to the induction of adaptive autophagy and increase longevity of eukaryotic cells. However, prolonged calorie restriction with excessive autophagy response is harmful and can stimulate a type II autophagic cell death. Despite the existence of a close relationship between calorie deprivation and autophagic response in different cell types, the precise molecular mechanisms associated with this phenomenon remain unclear. Here, we aimed to highlight the possible effects of prolonged and short-term calorie restriction on autophagic response and cell homeostasis.

    Abstract The COVID-19 pandemic has profoundly influenced public health and contributed to global economic divergences of unprecedented dimensions. Due to the high prevalence and mortality rates, it is then expected that the consequence and public health challenges will last for long periods. The rapid global spread of COVID-19 and lack of enough data regarding the virus pathogenicity multiplies the complexity and forced governments to react quickly against this pandemic. Stem cells represent a small fraction of cells located in different tissues. These cells play a critical role in the regeneration and restoration of injured sites. Because of their specific niche and a limited number of stem cells, the key question is whether there are different anti-viral mechanisms against viral infection notably COVID-19. Here, we aimed to highlight the intrinsic antiviral resistance in different stem cells against viral infection. These data could help us to understand the possible viral infections in different stem cells and the activation of specific molecular mechanisms upon viral entrance.

    Abstract The regeneration of cutaneous tissue is one of the most challenging issues in human regenerative medicine. To date, several studies have been done to promote cutaneous tissue healing with minimum side effects. The healing potential of polyurethane (PU)/Poly (caprolactone)-poly (ethylene glycol)-poly (caprolactone) (PCEC)/chitosan (CS) (PCS) nanofibrous mat with cationic photosensitizer meso tetrakis (N-methyl pyridinium-4-yl) porphyrin tetratosylate salt (TMP) was examined. The CS tripolyphosphate nanoparticles (CSNPs) were prepared and loaded by TMP to provide an efficient drug release system (TMPNPs) for delivery of TMP to promote wound healing. In in vitro setting, parameters such as bactericidal effects, cytocompatibility, and hemolytic effects were examined. The healing potential of prepared nanofibrous mats was investigated in a rat model of full-thickness cutaneous injury. PCS/TMP/TMPNPs nanofibers can efficiently release porphyrin in the aqueous phase. The addition of TMPNPs and CS to the PU backbone increased the hydrophilicity, degradation, and reduced mechanical properties. The culture of human fetal foreskin fibroblasts (HFFF2) on PCS/TMP/TMPNPs scaffold led to an increased survival rate and morphological adaptation analyzed by MTT and SEM images.

    Abstract Abstract The existence of active crosstalk between cells in a paracrine and juxtacrine manner dictates specific activity under physiological and pathological conditions. Upon juxtacrine interaction between the cells, various types of signaling molecules and organelles are regularly transmitted in response to changes in the microenvironment. To date, it has been well-established that numerous parallel cellular mechanisms participate in the mitochondrial transfer to modulate metabolic needs in the target cells. Since the conception of stem cells activity in the restoration of tissues’ function, it has been elucidated that these cells possess a unique capacity to deliver the mitochondrial package to the juxtaposed cells. The existence of mitochondrial donation potentiates the capacity of modulation in the distinct cells to achieve better therapeutic effects. This review article aims to scrutinize the current knowledge regarding the stem cell’s mitochondrial transfer capacity and their regenerative potential.

    Abstract Objectives: There are still challenges regarding c-kit+ cells' therapeutic outcome in the clinical setting. Here, we examined the c-kit+ cell effect on the alleviation of asthma by modulating miRNAs expression.
    Materials and methods: To induce asthma, male rats were exposed to ovalbumin. Bone marrow-derived c-kit+ cells were enriched by MACS. Animals were classified into four groups (6 rats each). Control rats received PBS intratracheally; Ovalbumin-sensitized rats received PBS intratracheally; Ovalbumin-sensitized rats received PBS intratracheally containing 3×105 c-kit+ and c-kit- cells. Cells were stained with Dil fluorescent dye to track in vivo condition. Pathological changes were monitored in asthmatic rats after transplantation of c-kit+ and c-kit- cells. Serum levels of IL-4 and INF-γ were measured by ELISA. Transcription of miRNAs (-126 and 133) was assessed by real-time PCR analysis.
    Results: Pathological examination and Th1 and Th2 associated cytokine fluctuation confirmed the occurrence of asthma in rats indicated by chronic changes and prominent inflammation compared with the control group (
    Conclusion: c-kit- cells were unable to promote any therapeutic outcomes in the asthmatic milieu. c-kit+ cells had the potential to diminish asthma-related pathologies presumably by controlling the transcription of miRNA-126 and -133.

    Abstract Human endothelial progenitor cells (EPCs) were isolated from cord blood samples and enriched by magnetic activated cell sorting method based on the CD133 marker. Cells were incubated with different doses of bacterial lipopolysaccharide, ranging from 2, 5, 10, 50, 100, 200, 250, 500, to 1000 µg/ml, for 48 h. The cell survival rate was determined by using MTT assay. To confirm activation of the toll-like receptor signaling pathway, PCR array analysis was performed. Protein levels of ERK1/2, p-ERK1/2, NF-ƙB and TRIF proteins were measured using western blotting. The content of TNF-α and lipoprotein lipase activity were analyzed by immunofluorescence imaging. Flow cytometric analysis of CD31 was performed to assess the maturation rate. Cell migration was studied by the Transwell migration assay. The expression of genes related to exosome biogenesis was measured using real-time PCR analysis. In vivo gel plug angiogenesis assay was done in nude mice. Lipopolysaccharide changed endothelial progenitor cells’ survival in a dose-dependent manner with maximum viable cells in groups treated with 2 µg/ml. PCR array analysis showed the activation of toll-like signaling pathways after exposure to LPS (p<0.05). Western blotting analysis indicated an induction of p-ERK1/2 and Erk1/2, NF-kB and TRIF in LPS-treated EPCs compared with the control (p<0.05). Immunofluorescence staining showed an elevation of TNF-α and lipoprotein lipase activity after lipopolysaccharide treatment (p<0.05). Lipopolysaccharide increased EPC migration and expression of exosome biogenesis-related genes (p<0.05). In vivo gel plug analysis revealed enhanced angiogenesis in cells exposed to bacterial lipopolysaccharide. Data highlighted the close relationship between the toll-like receptor signaling pathway and functional activity in EPCs.

Both c-kit+ and c-kit- cells were verified in pulmonary niche. Administration of c-kit positive cells had the potential to change INF-γ/IL-4 ratio close to the normal values compared with matched-control asthmatic rats (p <0.05). We also found that c-kit+ cells regulated the expression of miRNA-126 and -133, indicated by an increase of miRNA-133 and decrease of miRNA-126 compared with cell-free sensitized groups (p <0.05). Conclusion: c-kit- cells were unable to promote any therapeutic outcomes in the asthmatic milieu. c-kit+ cells had the potential to diminish asthma-related pathologies presumably by controlling the transcription of miRNA-126 and -133.
