Abstract Yes-associated protein 1 (YAP1) is a downstream effector of the Hippo signaling pathway, and it is involved in tumorigenesis, tissue repair, growth, and development. In this review, the biological roles and the mechanisms of YAP1 in mediating stem cell fate decisions are discussed, including cell proliferation, differentiation, and apoptosis. In general, YAP1 promotes the proliferation and differentiation of stem cells, including embryonic stem cells and adult stem cells. It inhibits apoptosis by binding to the transcription factors, e.g., transcriptional enhanced associate domain (TEAD), Smad, runt-related transcription factor 1/2, p73, p63, and Erb84, to maintain tissue homeostasis. The translocalization of YAP1… More >

Abstract The pathogenesis of myelodysplastic syndrome (MDS) may be related to the abnormal expression of microRNAs (miRNAs), which could influence the differentiation capacity of mesenchymal stem cells (MSCs) towards adipogenic and osteogenic lineages. In this study, exosomes from bone marrow plasma were successfully extracted and identified. Assessment of miR-103-3p expression in exosomes isolated from BM in 34 MDS patients and 10 controls revealed its 0.52-fold downregulation in patients with MDS compared with controls (NOR) and was downregulated 0.55-fold in MDS-MSCs compared with NOR-MSCs. Transfection of MDS-MSCs with the miR-103-3p mimic improved osteogenic differentiation and decreased adipogenic differentiation in vitro, while inhibition… More >

Abstract Atopic dermatitis (AD) is a chronic cutaneous inflammatory disease caused by an interaction between genetic, immune and epidermal barrier factors. Several treatments can be used to treat this disease but there are patients that do not respond to actual drugs. So, there is a need to develop effective therapies for AD. Mesenchymal stem cells (MSCs) are non-hematopoietic multipotent adult progenitor cells with immunomodulatory power and self-regenerating capacity to repair tissue damage, so they could be a potential effective treatment for AD. MSCs-Conditioned Medium (CM) and MSCs-exosomes are cell-free preparation with molecules secreted by stem cells that could be also beneficial… More >

Abstract In order to obtain larger, clinical-scale and practical-scale bone grafts, we have designed both tailored scaffolds and tailored bio incubator with optimal bio-production characteristics. Using DIC files to Simpleware Scan-IP (Simple-ware-exeter United Kingdom), we have digitally reconstructed segmental additive bone-tissue in order to perform images processing. Both hydroxyapatite and tannin composites have been used in order to get the final bone modules combined for retexturing of segmental bone defect. We have found that sectioning of bone segment deficiency reorganizations into well disk-shaped design permits one to standardize the cell culture and seeding protocol, to get better products. The present study… More >

Abstract The aim of this study was to investigate the potential biological activities of nutlin-3 in the regulation of growth and proliferation of non-small cell lung cancer (NSCLC) stem cells (CSCs), which may help in sensitizing to axitinib-induced apoptosis. Nutlin-3 induction of p53 expression was used to test its role in controlling the cell division pattern and apoptosis of NSCLC cells. A549 cells and H460 cells were pretreated with nutlin-3 and then treated with either an Akt1 activator or shRNA-GSK3 , to investigate the potential role of p53 sensitization in the biological effects of axitinib. We also determined the expression levels… More >

Abstract Pancreatic ductal adenocarcinoma (PDAC) is universally acknowledged as the cancer with the highest mortality rate. Berberine has high medicinal value and has been used as an anti-cancer agent. Hence the purpose of this study was to investigate the anti-cancer effect of berberine in PDAC. Berberine was shown to have a selective anti-cancer effect on PDAC by MTT assay in vitro. Pancreatic cancer stem cells (PCSCs), regulated by epithelial–mesenchymal transition (EMT), could promote the proliferation of PDAC cells. However, berberine suppressed the proliferation and stemness of PCSCs through immunofluorescence staining, stem cell sphere assays and so forth in vitro. In vivo,… More >

Abstract The complex mechanism of degenerative diseases and the non-specific modulation of regenerative targets are topics that need to be elucidated in order to advance the use of stem cells in improvement of neurodegenerative diseases. From pre-transplantation through post-transplantation, there are many changes in the conditions, both inside and outside of the stem cells that have not been carefully considered. This has hindered development in the field of cell therapy and regeneration. This viewpoint highlights the potential implications of intracellular and extracellular alterations of stem cells in transplanted areas at risk of neurodegenerative disease. More >

Abstract Detrimental immune response has a crucially important role in the development and progression of inflammatory eye diseases. Inflammatory mediators and proteolytic enzymes released by activated immune cells induce serious injury of corneal epithelial cells and retinal ganglion cell which may result in the vision loss. Mesenchymal stem cells (MSCs) are regulatory cells which produce various immunosuppressive factors that modulate phenotype and function of inflammatory immune cells. However, several safety issues, including undesired differentiation and emboli formation, limit clinical use of MSCs. MSC-derived exosomes (MSC-Exos) are nano-sized extracellular vesicles which contain all MSC-derived immunoregulatory factors. Intraocular administration of MSC-Exos efficiently attenuated… More >

Abstract Mesenchymal stem cells (MSCs) are multipotent cells usually isolated from bone marrow, endometrium, adipose tissues, skin, and dental pulp. MSCs played a crucial role in regenerative therapy and have been introduced as an interdisciplinary field between cell biology and material science. Recently, MSCs have been widely explored for their application in regenerative medicine and COVID-19 treatment. Different approaches to evaluate the future of biomaterials and stem cell properties have been developed. However, misconceptions and ethical issues still exist, such as MSCs being non-angiogenic, anti-apoptotic, and immunoregulatory competencies. Embryonic stem cells isolation primarily requires the consent of donors and can include… More >

Abstract All non-immortalized mesenchymal stem cells have a limited proliferative potential, that is, replicative senescence (RS) is an integral characteristic of the life of all mesenchymal stem cells (MSCs). It is known that one of the important signs of RS is a decrease of cell motility, and that violations of migration processes contribute to the deterioration of tissue regeneration. Therefore, the characterization of the properties of the cell line associated with RS is a prerequisite for the effective use of MSCs in restorative medicine. One of the key proteins regulating cell motility is the small GTPase RhoA. The main purpose of… More >
