Proliferation And Migration

Adipose-derived stem cells (ASCs) are an attractive source for regenerative medicine as they can be easily isolated, rapidly expandable in culture and show excellent in vitro differentiation potential. Acetylcholine (ACh), one of the main neurotransmitters in central and peripheral nervous systems, plays key roles in the control of several physiological processes also in non-neural tissues. As demonstrated in our previous studies, ACh can contribute to the rat ASCs physiology, negatively modulating ASCs proliferation and migration via M2 muscarinic receptor (mAChR) activation. In the present work we show that rat ASCs also express α7 nicotinic receptors (nAChRs). In particular, we have investigated the effects mediated by the selective activation of α7 nAChRs, which causes a reduction of ASC proliferation without affecting cell survival and morphology, and significantly promotes cell migration via upregulation of the CXCR4 expression. Interestingly, the activation of the α7 nAChR also upregulates the expression of M2 mAChR protein, indicating a cooperation between muscarinic and nicotinic receptors in the inhibition of ASC proliferation.

Healing of ruptured tendons remains a clinical challenge because of its slow progress and relatively weak mechanical force at an early stage. Extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) have therapeutic potential for tissue regeneration. In this study, we isolated EVs from adipose-derived stem cells (ADSCs) and evaluated their ability to promote tendon regeneration. Our results indicated that ADSC-EVs significantly enhanced the proliferation and migration of tenocytes in vitro. To further study the roles of ADSC-EVs in tendon regeneration, ADSC-EVs were used in Achilles tendon repair in rabbits. The mechanical strength, histology, and protein expression in the injured tendon tissues significantly improved 4 weeks after ADSC-EV treatment. Decorin and biglycan were significantly upregulated in comparison to the untreated controls. In summary, ADSC-EVs stimulated the proliferation and migration of tenocytes and improved the mechanical strength of repaired tendons, suggesting that ADSC-EV treatment is a potential highly potent therapeutic strategy for tendon injuries.

Abstract Background Stromal cells recruited to the tumor microenvironment and long non-coding RNAs (lncRNAs) in the tumor cells regulate cancer progression. However, their relationship is largely unknown. Methods In the current study, we identified the effects of lncRNA FAM83H-AS1, induced by adipose-derived stem cells (ADSCs) during tumor development, and explored the underlying mechanisms using a coculture cell model. Adipose tissues were obtained from healthy female donors, the expression of stromal markers on cell surface of expanded ADSCs were confirmed using immunofluorescence analysis. The breast and pancreatic cancer cells were cultured with or without ADSCs using 24-well transwell chamber systems with 8.0 µm pore size. Results Our results showed that FAM83H-AS1 was upregulated in breast and pancreatic cancers and associated with poor prognosis. ADSCs further induced FAM83H-AS1 and increased tumor cell proliferation via promoting G1/S transition through cyclin D1, CDK4 and CDK6. Wound healing, modified Boyden chamber and immunoblotting assays demonstrated that ADSCs induced epithelial-mesenchymal transition and migration of breast and pancreatic cancer cells in a FAM83H-AS1-dependent manner. And ADSC-induced FAM83H-AS1 increased unfolded protein response through AKT/XBP1 pathway. Conclusion In conclusion, our results indicated that ADSCs promoted breast and pancreatic cancer development via inducing cell proliferation and migration, as well as unfolded protein response through FAM83H-AS1.

MicroRNAs (miRNAs) are potential therapeutic targets in endometrial cancer, but the difficulties associated with their delivery to tumor target cells have hampered their applications. Human umbilical cord mesenchymal stem cells (hUCMSCs) have a well-recognized tumor-homing ability, emphasizing the capacity of tumor-targeted delivery of extracellular vesicles. hUCMSCs release extracellular vesicles rich in miRNAs, which play a vital role in intercellular communication. The purpose of this study was to verify a potential tumor suppressor microRNA, miR-302a, and engineered hUCMSC extracellular vesicles enriched with miR-302a for therapy of endometrial cancer. Here, we observed that miR-302a was significantly downregulated in endometrial cancer tissues when compared with adjacent tissues. Overexpression of miR-302a in endometrial cancer cells robustly suppressed cell proliferation and migration. Meanwhile, the proliferation and migration were significantly inhibited in endometrial cancer cells when cultured with miR-302a-loaded extracellular vesicles derived from hUCMSCs. Importantly, our data showed that engineered extracellular vesicles rich in miR-302 significantly inhibited the expression of cyclin D1 and suppressed AKT signaling pathway in endometrial cancer cells. These results suggested that exogenous miR-302a delivered by hUCMSC-derived extracellular vesicles has exciting potential as an effective anticancer therapy.
