BMSC-derived exosomes from congenital polydactyly tissue alleviate osteoarthritis by promoting chondrocyte proliferation. Cell Death Discov 2020; 6:142. [PMID: 33303743 PMCID: PMC7730395 DOI: 10.1038/s41420-020-00374-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 10/12/2020] [Accepted: 11/09/2020] [Indexed: 12/12/2022] Open
Abstract
In the past decade, mesenchymal stem cells (MSCs) have been widely used for the treatment of osteoarthritis (OA), and exosomes may play a major role. Here, we acquired a special kind of MSCs from the bone marrow of surgically resected tissue from the hand of a patient with polydactyly. Experiments were focused on the role of polydactyly bone marrow-derived MSCs (pBMSCs) in osteoarthritis. The results showed that the pBMSCs had a greater ability than the BMSCs to differentiate into chondrocytes. Mechanistically, the expression of BMP4 was significantly higher in the pBMSCs than it was in the BMSCs. Furthermore, we showed that the migration and proliferation of chondrocytes were stimulated by exosomes secreted by pBMSC (pBMSC-EXOs). Notably, the downregulation of BMP4 in pBMSCs by siRNA inhibited both the chondrogenic differentiation potential of the MSCs and the function of the chondrocytes. In addition, the injection of pBMSC-EXOs and BMSC-EXOs attenuated OA in an OA mouse model, but the pBMSC-EXOs had a superior therapeutic effect compared with that of the BMSC-EXOs. Taken together, the data indicate that pBMSCs have greater ability to differentiate into chondrocytes and regulate chondrocyte formation through BMP4 signaling. Therefore, pBMSC-EXOs may represent a novel treatment for OA.

Induction of a proliferative response in the zebrafish retina by injection of extracellular vesicles. Exp Eye Res 2020; 200:108254.

Abstract
Ongoing research using cell transplantation and viral-mediated gene therapy has been making progress to restore vision by retinal repair, but targeted delivery and complete cellular integration remain challenging. An alternative approach is to induce endogenous Müller glia (MG) to regenerate lost neurons and photoreceptors, as occurs spontaneously in teleost fish and amphibians. Extracellular vesicles (EVs) can transfer protein and RNA cargo between cells serving as a novel means of cell-cell communication. We conducted an in vivo screen in zebrafish to identify sources of EVs that could induce MG to dedifferentiate and generate proliferating progenitor cells after intravitreal injection into otherwise undamaged zebrafish eyes. Small EVs (sEVs) from C6 glioma cells were the most consistent at inducing MG-derived proliferating cells. Ascl1a expression increased after intravitreal injection of C6 sEVs and knockdown of ascl1a inhibited the induction of proliferation. Proteomic and RNAseq analyses of EV cargo content were performed to begin to identify key factors that might target EVs to MG and initiate retina regeneration.

Abstract
The utilization of stem cells as novel carriers to target tissues or organs of interest is a challenging task in delivery system. The composite cellular delivery with diverse signalling molecules as therapeutics increases stem cell capability and possesses the promising potential to augment, modify or commence localized or systemic restoration for vital applications in regenerative medicine. The inherent potential of stem cells to immigrate and reside at wounded site facilitates transportation of genes, polypeptides or nanosized molecules. Liposomes are micro- to nano-lipidic vesicles formed in aqueous solutions to encapsulate complex hydrophilic and lipophilic chemical substances. Moreover, these novel nanocarriers provide safer and efficient delivery of bioactives together with their potential applications in vaccine production, cosmeceuticals, imaging and diagnostic purpose. Tissue engineering promotes rejuvenation process and involves the synchronized utilization of cells with 3D bio-material scaffolds to fabricate living structures. This strategy requires regulated stimulus of cultured cells through combined mechanical signals and bioactive agents. This review highlights and summarizes the mechanism involved in stem cell migration, strategies to enhance homing, safety and efficacy studies of stem cells in various disease models and discusses the potential role of liposomes in prolonged and localized delivery of bioactives for regenerative medicines and tissue engineering techniques. Graphical Abstract Role of PEGylated liposomes in cancer stem cell therapy.

Abstract
Purpose In this study, we aim to investigate whether mesenchymal stem cell (MSC)-derived exosomes (MSC-Exos) could regulate hyperglycemia-induced retinal inflammation by transferring microRNA-126 (miR-126). Methods MSC-Exos were isolated from the media of human umbilical cord-derived mesenchymal stem cells (hUCMSCs), and this isolation was followed by the transfer of miR-126. MSC-Exos or MSC-Exos overexpressing miR-126 were intravitreally injected into diabetic rats in vivo and were cocultured with high glucose-affected human retinal endothelial cells (HRECs) in vitro. Plasma samples were obtained from the vitreous of rats and from HREC cells after treatment for ELISA assay. Retinal sections were examined using immunohistochemistry. RT-PCR and Western blotting were conducted to assess the levels of high-mobility group box 1 (HMGB1), NLRP3 inflammasome, and NF-κB/P65 in retinas and HRECs. Results Our results showed that hyperglycemia greatly increased inflammation in diabetic rats or HRECs exposed to high glucose, increasing the levels of caspase-1, interleukin-1β (IL-1β) and IL-18. The administration of MSC-Exos could effectively reverse this reaction. Compared to control MSC-Exos, MSC-Exos overexpressing miR-126 more successfully suppressed the HMGB1 signaling pathway and suppressed inflammation in diabetic rats. The administration of miR-126-expressing MSC-Exos significantly reduced high glucose-induced HMGB1 expression and the activity of the NLRP3 inflammasome in HRECs. Conclusions miR-126 expression in MSC-Exos reduces hyperglycemia-induced retinal inflammation by downregulating the HMGB1 signaling pathway.

Abstract
A more comprehensive understanding of the human ageing process is required to help mitigate the increasing burden of age-related morbidities in a rapidly growing global demographic of elderly individuals. One exciting novel strategy that has emerged to intervene involves the use of extracellular vesicles to engender tissue regeneration. Specifically, this employs their molecular payloads to confer changes in the epigenetic landscape of ageing cells and ameliorate the loss of functional capacity. Understanding the biology of extracellular vesicles and the specific roles they play during normative ageing will allow for the development of novel cell-free therapeutic interventions. Hence, the purpose of this review is to summarise the current understanding of the mechanisms that drive ageing, critically explore how extracellular vesicles affect ageing processes and discuss their therapeutic potential to mitigate the effects of age-associated morbidities and improve the human health span.

Abstract
The use of stem cells as carriers for therapeutic agents is an appealing modality for targeting tissues or organs of interest. Combined delivery of cells together with various information molecules as therapeutic agents has the potential to enhance, modulate or even initiate local or systemic repair processes, increasing stem cell efficiency for regenerative medicine applications. Stem-cell-mediated delivery of genes, proteins or small molecules takes advantage of the innate capability of stem cells to migrate and home to injury sites. As the native migratory properties are affected by in vitro expansion, the existent methods for enhancing stem cell targeting capabilities (modified culture methods, genetic modification, cell surface engineering) are described. The role of various nanoparticles in equipping stem cells with therapeutic small molecules is revised together with their class-specific advantages and shortcomings. Modalities to circumvent common challenges when designing a stem-cell-mediated targeted delivery system are described as well as future prospects in using this approach for regenerative medicine applications.

Abstract
PURPOSE OF REVIEW Microvesicles (MVs) have been recognised as mediators of stem cell function, enabling and guiding their regenerative effects. RECENT FINDINGS MVs constitute one unique size class of extracellular vesicles (EVs) directly shed from the cell plasma membrane. They facilitate cell-to-cell communication via intercellular transfer of proteins, mRNA and microRNA (miRNA). MVs derived from stem cells, or stem cell regulatory cell types, have proven roles in tissue regeneration and repair processes. Their role in the maintenance of healthy tissue function throughout the life course and thus in age related health span remains to be elucidated. SUMMARY Understanding the biogenesis and mechanisms of action of MVs may enable the development of cell-free therapeutics capable of assisting in tissue maintenance and repair for a variety of age-related degenerative diseases. This review critically evaluates recent work published in this area and highlights important new findings demonstrating the use of MVs in tissue regeneration.

Abstract
Entering the new millennium, nobody believed that there was the possibility of discovering a new cellular type. Nevertheless, telocytes (TCs) were described as a novel kind of interstitial cell. Ubiquitously distributed in the extracellular matrix of any tissue, TCs are regarded as cells with telopodes involved in intercellular communication by direct homo- and heterocellular junctions or by extracellular vesicle (EVs) release. Their discovery has aroused the interest of many research groups worldwide, and many researchers regard them as potentially regenerative cells. Given the experience of our laboratory, where these cells were first described, we review the evidence supporting the fact that TCs release EVs, and discuss alternative hypotheses about their future implications.
